1. About 





QuakeSpasm
is a modern, cross-platform Quake 1 engine based on 
FitzQuake.


It includes support for 64 bit CPUs and custom music playback, a new
sound driver, some graphical niceities, and numerous bug-fixes and other improvements.


Quakespasm utilizes either the SDL or SDL2 frameworks, so choose which one works best for you.
SDL is probably less buggy, but SDL2 has nicer features and smoother mouse input - though no CD support.



2. Downloads 












3. Hints 




Visit the 
FitzQuake homepage for a full run-down of the engine's commands and variables.








3.1 Music Playback




Quakespasm can play various external music formats, including MP3, OGG and FLAC.






3.2 Controller Support




The SDL2 variant of Quakespasm supports Xbox 360 style game controllers.


The default configuration uses the left analog stick for movement and the right for looking.


If your controller doesn't work you can try placing 
this file in your Quake directory, it is a community-maintained database that adds support for more controllers to SDL2.



Cvars










Buttons



Some of the controller buttons are hardcoded to allow navigating the menu:








These buttons can be bound normally:






quakespasm.pak contains a default.cfg which has been updated to give some default bindings. L/R shoulder buttons are bound to weapon switching, and L/R triggers are jump and attack.


The controller support started as Jeremiah Sypult's implementation in Quakespasm-Rift and also uses ideas and code from LordHavoc (DarkPlaces).



4. Compiling and Installation




Quakespasm's (optional) custom data is now stored in the file quakespasm.pak. This file should be placed alongside your quakespasm binary and id1 directory.


To checkout the latest version of QuakeSpasm, do:
svn co svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm


4.1 Linux/Unix 




After extracting the source tarball, browse the Makefile and edit the music streaming options, then



make
cp quakespasm /usr/local/games/quake (for example)






Compile time options include




Streaming music playback requires "libmad" or "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG files.


The project can also be built with Codeblocks (project files included).


4.2 Windows 




The QuakeSpasm developers cross-compile windows binaries using 
MinGW and 
Mingw-w64.


The project can also be built using Visual Studio 2005 (or newer).


4.3 Mac OS X 




A Quakespasm App (including program launcher and update framework) can be made using the Xcode template found in the MacOSX directory.


Alternatively, have a look at Makefile.darwin for more instructions on building from a console.


5. Known Bugs 



Brightness issues should be fixed with GLSL gamma in 0.90.1, if your system supports OpenGL 2. For reference on older systems:

 
Some versions of Xorg and SDL have brightness issues.

Try setting "export SDL_VIDEO_X11_NODIRECTCOLOR=1", or if you have Xorg >= 7.5 and broken brightness,
these patched libSDL binaries may help.

Fitzquake version 0.85, Feb 12, 2009

Fitzquake is a modified glquake based on the source code released by id 
Software. My primary focus is fixing a lot of the rendering bugs which made 
glquake inferior to the software renderer. My secondary focus is adding 
conveniences for mappers and general users. I am also slowly adding support for
new modding or mapping features such as skyboxes, fog, and colored light. 

While I have made extensive changes to the code, I pretty much use the same 
OpenGL features that the original glquake uses. Therefore, if you can run 
glquake, you can probably run Fitzquake. 

I am not finished working on this project, so bug reports and feature requests
are welcome.

History
================================================================================

changes in 0.85
---------------
	- increased limits		
		- added a network protocol 666, which supports higher limits, entity alpha, and more (see command "sv_protocol")
		- can load and play all known limits-breaking maps, including masque, warpspasm, indian summer, sickbase, 768_negke, digs04, omlabx, and bod.
		- increased MAX_MODELS from 256 to 2048 (and MAX_MOD_KNOWN from 512 to 2048) (requires the new protocol)  Prints a warning if you exceed the old limit.
		- increased MAX_SOUNDS from 256 to 2048 (requires the new protocol)  Prints a warning if you exceed the old limit.
		- increased the upper limit for the "max_edicts" cvar to 32000 (requires the new protocol for entities past 8192 to play sounds)
		- models with more than 256 frames can now actually use those frames (requires the new protocol)
		- fixed crash when marksurfaces > 32767, raising the effective limit to 65k. Prints a warning if you exceed 32767.
		- fixed crash or other weird behavior when faces > 32767, raising the effective limit to 65k. Prints a warning if you exceed 32767. 
		- fixed crash when nodes > 32767, raising the effective limit for leafs+nodes to 65k. Prints a warning if you exceed 32767. 
		- increased clipnode capacity from 32k to 65k. Prints a warning if you exceed 32767.
		- increased MAX_MAP_LEAFS from 8192 to 32k (these are visleafs, not total leafs.) Prints a warning if you exceed the old limit.
		- increased MAX_STATIC_ENTITIES from 128 to 512. Prints a warning if you exceed the old limit. 
		- increased MAX_VISEDICTS from 256 to 1024, which should fix static entities flickering in large maps. Prints a warning if you exceed the old limit.
		- increased MAX_EFRAGS from 640 to 2048.  Should reduce the "Too many efrags!" messages.  Prints a warning if you exceed the old limit.
		- increased MAX_LIGHTMAPS from 64 to 256, meaning you can load 4 times as much lightmap data before getting an "Allocblock:full" error.  Prints a warning if you exceed the old limit.
		- increased MAX_GLTEXTURES from 1024 to 2048
		- increased MAX_BEAMS from 24 to 32 and MAX_TEMP_ENTITIES from 64 to 256, so you can have more lightning bolts now
		- increased increase MAX_DLIGHTS from 32 to 64
		- eliminated "packet overflow" errors in single-player mode on all known maps, by increasing MAX_DATAGRAM from 1024 to 32000 (NET_MAXMESSAGE and MAX_MSGLEN were also increased accordingly.) In multiplayer (including COOP,) the MAX_DATAGRAM size is 1400 because the MTU on most internet routers is ~1450, and anything above this could get fragmented and lost since datagram packets use UDP.  Prints warning when packetsize exceeds the standard datagram size.
		- increased signon buffer capacity, should eliminate sz_getspace  errors (example: hard mode coop crash on Travail's qte2m1.bsp.)  Prints a warning when signon buffer is too big for standard servers.
		- "no free edicts" error now spits you back to the console instead of crashing
	- visual improvements
		- added model interpolation for animation and movement.  See cvars r_lerpmodels, r_lerpmove, r_nolerp_list.
		- added interpolation on the gun kick motion, and ability to disable gun kick entirely (see cvar "v_gunkick")
		- disabled torches/bolts casting shadows
	- more content support
		- added support for per-entity alpha, and it works even without a custom progs.dat, works on static entities too, and both bsp and mdl models.  Set values directly in the map and/or control it with quakec. When setting alpha, a value of "0" is interpreted as "default", which means 1.0 for most things, but for water polygons it t means obey the value of r_waterwarp.  A value greater than 0, up to 1.0, will explicitly set the alpha, and override r_wateralpha for water polygons.  A value of -1 will explictly set the alpha to 0 (invisible), and override r_wateralpha.  (requires the new protocol, except for alpha -1, which makes things invisible even with protocol 15)
		- can playback protocol 15 demos containing the nonstandard U_TRANS bit, as recorded by nehahra, joequake, and aguirre's engine.  When the server says it is running protocol 15, and the U_TRANS bit is encountered, fitzquake will assume it's the Nehahra protocol and parse it accordingly.
		- added support for -quoth command line switch. Loads quoth content regardless of current gamedir, and enables hipnotic statusbar layout.  This allows you to load a mod that requires quoth, but is in a separate directory (i.e. fitzquake.exe -quoth -game warp)
		- fullbrights now use additive blending instead of alpha blending. This allows me to support external glowmaps, and entity transparency with fullbrights/glowmaps.  In some cases, additive fullbrights are rendered using multitexture, but only if GL_EXT_texture_env_add is available.  The command line option -nocombine will disable the use of GL_EXT_texture_env_add.
		- added support for external glowmaps (names must end in _luma or _glow)
		- added support for external liquid textures (name your files #water instead of *water)
		- added support for map-specific texture directories (put textures in /textures/mapname/)
	- interface improvements
		- improved crosshair accuracy somewhat for protocol 15, and improved it a lot in protocol 666
		- rearranged scorebar so that map titles as long as 40 chars can be displayed without scrolling
		- statusbar displayed values now cap at 999 rather than displaying truncated numbers (1001 will be displayed as 999 instead of 001)
		- tab completion cycle order now alphabetized as a whole rather than grouped by type
		- added scr_conscale cvar (see below)
		- added scr_crosshairscale cvar (see below)
		- added scr_sbaralpha cvar (see below)
		- scr_showfps and scr_clock display now use same scale as console (scr_conscale, scr_conwidth)
		- video menu now shows aspect ratio of selected video mode
		- added aguirRe's trick of making the window perfectly cover the screen with no titlebar/borders, if you create a windowed mode with height/width equal to the desktop size. (not tested on dual monitors, though.)
	- developer features
		- added ability to monitor various stats that change dynamically, such as packet size, temp entities, and visedicts. (see cvar "devstats")
		- restricted spammy messages "packet overflow", "beam list overflow", and "too many efrags" to repeat at most once every 3 seconds
		- r_showbboxes now draws point entities too
		- "mcache" command now gives you a total number of models (note, this is a list of all loaded models, not just the current level's model precaches)
		- "soundlist" command now gives you a total number of sounds (note, this is a list of all loaded sounds, not just the current level's sound precaches)
		- "give" command can now give armor values above 200
		- added imagedump command (see below)
		- "x is not a field" message is now shown only if developer = 1
	- bugfixes
		- added Baker's fixes for Intel display adapters
		- fixed tab completion cycle never reaching certain commands/cvars in list
		- fixed -dinput mouse doesn't work after vid_restart
		- fixed rotated alias models incorrectly culled
		- fixed sky animation on brush models
		- fixed "invalid pixel format" error when switching between two video modes with the same bit depth, on certain chipsets (Baker had this problem)
		- fixed alt-tab fullscreen trashed window on some nvidia, intel cards (from Baker)
		- fixed some TGAs load upside down
		- fixed non-square PCX loading appears interlaced
		- fixed PCX loading from inside pakfiles appears as random noise
		- fixed player skin corruption bug (thanks aguirRe)
		- fixed improperly trying to colormap the playermodel before a map is loaded, after switching games (could cause a crash or discolored textures)
		- fixed too-dark fog on world/brushmodels with -nomtex
		- fixed overbright models too light with fog and -nocombine
		- fixed r_wateralpha support on brush entities
		- fixed grenade shadows spinning wildly instead of staying on the ground
		- fixed solid fogged sky was not quite the same color as solid fogged geometry, for certain colors of fog
		- fixed trigger_changelevel with missing map causes apparent hang
		- fixed hang when r_stereo and r_lightmap are both enabled
		- fixed "W_GetLumpinfo" crash when a graphic is missing from gfx.wad. Prints a console message instead.  Missing graphics will be drawn as a checkerboard image. Note: conchars is the one graphic that must be in the gfx.wad, since the console won't even function without it.
		- fixed accidentally stripping -hipnotic and -rogue directories when switching games
		- fixed give command doesn't update currentammo
		- fixed changing gamedirs while a skybox is loaded sometimes corrupts textures/lightmaps in the next map loaded
		- fixed unnecessary creation of "glquake" subdirectory
		- fixed 0Hz/0bpp showing up in video menu sometimes
		- fixed -aliases triggered on alt-tab
		- fixed con_logcenterprint considering identical messages to be duplicates even though the map has changed in between
		- fixed hang in proxmap2, when going through one of the teleporters (thanks spirit, mh)
		- fixed lightning bolt memory corruption crash (rare)
	- source cleanup
		- removed all ASM code from source, and removed gas2masm project
		- cleaned up unnecessary library dependencies in source release
		- renamed local variable "errno" to fix a compiling problem on visual c++ express edition
		- added dxsdk folder to source release

cvars:

	- devstats. default 0.  If 1, prints various the current and peak values of various stats that change over time, such as packetsize, and edicts. Note: even if devstats is set to 0, fitzquake will keep track of peak values so when you turn it on, the peaks are accurate.  Devstats display scale follows console text scale.

	- r_lerpmodels. default 0. If 1, do interpolation on model animations, with exceptions for torches (r_nolerp_list) & muzzleflares (interpolation is suspended for two frames if EF_MUZZLEFLASH is encountered, on the assumption a muzzleflare happens at the same time.) If 2, lerp all animations, without exception.  If 0, disable interpolation (to mimic standard quake.)

	- r_lerpmove. default 0. If 1, do movement interpolation on MOVETYPE_STEP entities (i.e. monsters.)  If 0, disable interpolation (to mimic standard quake.)  I recommend that you use r_lerpmove and r_lerpmodels together, or turn them both off, otherwise monsters will move strangely.

	- r_nolerp_list. Contains a comma-separated list of filenames of models to exclude from lerping. Filename must include the relative path and extension, for example "progs/flame.mdl".  The default is "progs/flame.mdl,progs/flame2.mdl,progs/braztall.mdl,progs/brazshrt.mdl,progs/longtrch.mdl,progs/flame_pyre.mdl,progs/v_saw.mdl,progs/v_xfist.mdl,progs/h2stuff/newfire.mdl". This should include all torches in id1, quoth, and bastion, which look bad when lerped, and the zerstorer chainsaw and xmen fist, which also look bad lerped.

	- r_skyfog. default 0.5.  Controls how much the sky is obscured by the fog.  0 = sky is completely unfogged, 1 = sky is completely fogged.

	- scr_conscale. default 1.  Scales the console text larger, but only has an effect when scr_conwidth is 0.

	- scr_crosshairscale. default 1. Scales the crosshair larger. 1 = normal, 10 = maximum enlargement

	- scr_sbaralpha. default 1.  Controls the transparency of the statusbar background. 0 = invisible, 1 = opaque (original quake behavior), in-between values give different levels of transparency.  Pro tip: set it to 0.99 and it will still appear opaque, but the 3D view will expand to fill the area on both sides of the statusbar.

	- v_gunkick. default 1.  If 1, standard quake view kick when you fire your gun.  If 2, interpolates the view kick.  If 0, disables view kick entirely.

commands:

	- imagedump. Dumps all loaded textures from opengl into tga files.  This shows the textures as they exist in opengl texture memory. Texture names containing '*' will be renamed with '#' instead.

	- sv_protocol. Sets the network protocol used by the server.  Default is 666.  Possible values are 15 (standard netquake protocol) or 666 (new fitzquake protocol.)  Changes to the protocol will not take effect until the next time you load/reload a level.  When running protocol 666, standard clients won't be able to connect to your server, and they won't be able to play any demos you record.  When running protocol 15, only 256 models and 256 sounds can be sent to the client, which means you would see invisible entities and not hear some sounds, when running a map or mod that has more than 256 models or sounds.  There is also some other data the server will suppress in protocol 15, such as per-entity alpha.  Also note, dzip's special demo compression does not work on demos that use modified protocols, so you will get a compression ratio no better than standard zip compression.

changes in 0.80
---------------

	- map loading is about four times faster.  This is due to some optimizations in the texture loading code.
	- video mode can now be changed in-game.  You can change resolution, color depth, refresh rate, and switch between windowed and fullscreen modes.  This can be accomplished easily using the video options menu, and is also available at the console using cvars. Note: if you launch fitzquake with -width, -height, -window, or -bpp in the command line, Fitzquake will use the command line settings and ignore whatever it reads from the config files at startup. However, you will still be able to change the video mode from the menu or the console as you like. Also note: to change video modes by execing a config file, the config file must include "vid_restart" after the other vid_ cvars have been set. (see cvars "vid_width," "vid_height," "vid_fullscreen," "vid_bpp," "vid_refreshrate," and commands "vid_restart," "vid_test")
	- added control of entity count limits (MAX_EDICTS.)  The default maximum has been increased from 600 to 1024.  It can be raised even higher (up to 8192 -- this is a limit set by the network protocol) using a cvar. (see cvar "max_edicts")
	- added control of vertical sync.  (see cvar "vid_vsync")
	- added control of anistropic filtering.  Anisotropic filtering is a method to improve texture clarity on surfaces when viewed at steep angles.  (see cvar "gl_texture_anisotropy")
	- console buffer size can now be set.  The command line option "-consize" allows you to specify the buffer size in kilobytes.  For reference, fitzquake's default buffer size is 64k, and glquake's is 16k.  16k is also the smallest size fitzquake will allow you to set.  Note: this buffer lives in the heap, so if you want to have a HUGE buffer, you might need to increase -heapsize also.
	- increased max surface extents from 256 (the software quake maximum) to 2000.  For reference, the glquake maximum is 512.  This should eliminate the "bad surface extents" crash when running some maps that could be played in glquake, but not fitzquake or winquake.
	- increased max vertices in an alias model from 1024 (the glquake maximum) to 2000 (the software quake maximum.)
	- increased MAX_CHANNELS from 128 to 512 and MAX_DYNAMIC_CHANNELS from 8 to 128
	- screenshot filenames are now in the format "fitz0000.tga", increasing the maximum number of screenshots per folder from one hundred to ten thousand.
	- vid_describemodes output cleaned up; now displays a list of valid refresh rates for each mode
	- added a more intuitive cvar control of slow motion/fast-forward for demos and live gameplay.  (see cvar "host_timescale")
	- "reset to defaults" option in the menu now executes the "resetall" command before loading default.cfg
	- game command now writes config.cfg to current gamedir before switching
	- +mlook is now saved to config.cfg
	- changed smallest allowed window size from 320x240 to 320x200
	- console cursor images are now hard-coded, and the insert mode cursor is now a vertical bar instead of an underscore. This was prompted by several popular mods (OUM, Xmen TC) using nonstandard cursors, which are incompatible the fitzquake console enhancements.
	- gl_farclip now defaults to 16384.  This should be high enough to handle even the largest open areas without unwanted clipping.  The only reason you'd want to lower this number is if you see z-fighting.
	- added cvar r_drawworld (see below)
	- added cvar r_showtris (see below)
	- added cvar r_showbboxes (see below)
	- added a command to cycle a cvar through a list of values. (see command "cycle")
	- mapname command now works on dedicated server.
	- added a hack to fix those white edges on the bottom of the large box of shells.  I feel dirty, but they look better, now.
	- changed stuffcmds behavior to allow hyphenated map names, config file names, etc. in the command line. (example: "fitzquake.exe +exec my-config.cfg +map my-map")  However, you still can't load a map or config file when the first character in the filename is a hyphen.
	- skybox loader now reverts to scrolling sky if all 6 skybox faces failed to load.
	- tweaked circular particles to match the apparent size of the square particles.
	- fixed crash when loading mods with large player skins (like the chainsaw mod, and PerQuake.)  Colormapping can now handle any size player texture (limited to the heapsize, of course.)
	- fixed bug where a replacement model in a mod is messed up becuase a matching .ms2 file in id1/glquake is present.  The fix is simply to disable all mesh caching, which slows down model loading a little.
	- fixed freeze when gl_overbright is 1 and either texture_env_combine or multitexture is disabled or not supported.
	- fixed "numgltextures == MAX_GLTEXTURES" crash when viewing multiplayer->setup menu.
	- fixed "numgltextures == MAX_GLTEXTURES" crash when playing large maps (nesp09,) due to frequent model recaches.
	- fixed bug where entities and water were not being drawn any frame in which a model had to be recached.
	- fixed skybox texture showing up in the place of other textures/skins/lightmaps, when the previous loaded map had a skybox.
	- fixed missing polygons on edges of screen when underwater and r_waterwarp is 1.
	- fixed missing polygons on edges of screen when r_stereo is enabled.
	- fixed long mapnames that scroll are truncated to be shorter than what appears in the console.  Well, sort of.  What I did was increase the maximum length from 39 to 127.  A mapname longer than 127 will still be truncated, but these are pretty rare.
	- fixed rogue's teamplay skin showing up as an all-white texture.
	- fixed checkerboard texture shows up sometimes when an animated texture has fullbright pixels on some frames, but not others (reactor core in junk.bsp)
	- fixed color 255 is not fullbright
	- fixed fuscia dots appearing in corners of resampled textures
	- fixed mapname command crashes when client is disconnected.
	- fixed cl_nolerp 1 screws up speed of demo playback
	- fixed annoying client-side step-up smoothing when in noclip mode (except on nonlocal servers.)
	- fixed scr_clock 2 displays hour twelve as "0" instead of "12"
	- fixed skip textured surfaces still drawn even after running tyrann's skip utility
	- fixed crash when loading a map with a sky texture where the "sky" in the texturename is not lowercase
	- fixed hang in e2m2 on easy skill, where you can shoot one of the buttons at the beginning and then trick-jump through the open gate.  Now it prints a warning message ("SV_TouchLinks: null link") and lets you keep playing.
	- fixed bug when viewsize < 100, and r_oldwater is 0, where you can see the water textures overlaying part of the brown frame around the viewport.
	- fixed bug where imagelist and r_speeds2 would report the same megabyte counts in both 16bpp and 32bpp mode, even though texture bpp should match (and does match) framebuffer bpp.  The numbers are now different and accurate for each bit depth.
	- removed cvars "vid_config_x," "vid_config_y," "vid_wait," "vid_nopageflip," "_vid_wait_override," "_vid_default_mode," "_vid_default_mode_win," and "vid_stretch_by_2," none of which glquake ever used.
	- removed cvar "vid_mode" and commands "vid_describemode" and "vid_nummodes," because of the new video mode handling.
	
cvars:

	- gl_texture_anisotropy. Controls the amount of anisotropy in texture filtering.  If 1 or less than 1, texture filtering is normal (isotropic.)  If greater than 1, increasing degrees of anisotropic filtering are used, up to the hardware maximum. Set value to 2 for 2x anisotropic, 4 for 4x, etc. Default 1.

	- host_timescale.  Scales the passage of time on client and server. Set to 0 or 1 for normal speed, less than 1 for slow motion, and greater than 1 for fast-forward.  If greater than 0, overrides host_framerate.  Default 0.
	
	- max_edicts. Sets the maximum number of entites on both the client and server. Default 1024. Acceptable values range from 256 to 8192. Set to 600 to mimic standard quake. Changes won't take effect until the next time a map is loaded. Note: if a client connects to a server, and the client's maximum is lower than the server's, the client will probably crash if it ever sees an entnum higher than its local max_edicts. Warning: you may need to increase -heapsize if you want a high max_edicts value.
	
	- r_drawworld. If 1, draw world as usual.  If 0, don't draw the world.  Default 1. (compare r_drawentities)
	
	- r_showbboxes. If 1, draw a wireframe bounding box around each entity.  Note that these are the server-side per-edict physics bounding boxes, not the client-side per-model rendering bboxes. If 0, disable this feature. Default 0.
	
	- r_showtris. If 1, draw wireframe outlines for every triangle in the scene. Like in Quake 3, the lines will be visible even through solid geometry.  If 2, draw the outlines only on visible surfaces (like r_showtris 2 in Medal of Honor.) If 0, disable wireframe overlay.  Default 0.
	
	- vid_bpp. Sets the color depth of the screen in fullscreen mode. Windowed mode ignores this setting. Can be 16 or 32. Default 16. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_fullscreen. If 1, fitzquake will run fullscreen. If 0, fitzquake will run in a window. Default 1. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_height. Sets the vertical screen/window resolution. Default 480. In windowed mode, cannot be less than 200. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_refreshrate. Sets the refresh rate of the screen in fullscreen mode. Windowed mode ignores this setting. Possible values include 60, 70, 72, 75, 85, etc.  Default 60. (Changes won't take effect until the next call to vid_restart.)

	- vid_width. Sets the horizontal screen/window resolution. Default 640. In windowed mode, cannot be less than 320. (Changes won't take effect until the next call to vid_restart.)

	- vid_vsync.  Set to 1 to enable vertical sync, which eliminates tearing, but caps your framerate at the monitor refreshrate.  Set to 0 to disable vertical sync, which allows tearing but doesn't cap your framerate. Default 0.  Note: If fitzquake detects that your driver settings have forced vsync to be disabled, it will post a message to the console saying so, and this cvar will have no effect.

commands:

	- "cycle   [ [ ...]]" to cycle a cvar through a list of values..  Note: this command will get stuck on a list that contains the same value more than once, such as "cycle blah 1 2 1 3". If you're doing anything that complex you can just use aliases.

	- vid_restart.  Tries to set a video mode that matches the values of vid_width, vid_height, vid_fullscreen, and, if vid_fullscreen is 1, vid_bpp and vid_refreshrate.
	
	- vid_test. Like vid_restart, except that after switching to the new mode pops up a confirmation dialogue.  This is useful if you are not sure what modes your monitor can handle, so you don't get stuck with a blank screen.  The dialogue has a time limit so that if you don't press a key within 5 seconds, it will revert to the previous mode.

changes in 0.75
---------------

	- totally rewritten bsp drawing code.  The new code combines the advantages of the gl_texsort 1 and gl_texsort 0 codepaths from glquake into one codepath that uses texture sorting and multitexture.  In my tests, i've found that it's about the same speed as glquake in low poly scenes (like the original quake levels,) but as you get into the thousands of wpolys, it's faster and faster.
	- 2x overbright lighting.  Lighting now looks like software quake.  Just like overbright lighting on models, overbright on world polys requires GL_EXT_texture_env_combine (TNT and later, voodoo4 and later.)  Without it, FitzQuake will be use two passes to render overbright world polys.  So if you don't have that extension, you might disable it for performance reasons.  (see cvar "gl_overbright")
	- colored lighting support using .lit files.
	- totally new water surface animation.  The new method requires no surface subdivision, isn't plagued by tearing and sparklies caused by tjunctions, and looks almost identical to software quake's water, and doesn't slow down on very large sheets of water. (see cvars "r_waterquality" and "r_oldwater")
	- old water aninmation fixed so that it doesn't look bad when gl_subdivide_size is 32 or lower.
	- can load external textures (currently targa and pcx) if they match the texture name in the bsp and are located in the id1/textures, or /textures directory.  At the moment no other images (skins, menu, etc.) can be replaced.
	- gamma correction now goes back to normal when Fitzquake loses focus.
	- tab completion now adds a space after the completed command/cvar if the cursor is at the end of the editline.
	- increased the max length of the video mode list from 30 to 80.  This should alleviate the problems people with newer cards were having trying to use some 32-bit modes -- there were so many 16-bit modes that they filled up the list before all 32-bit modes could be detected.  The video menu will still only list a certain number of modes due to space constraints, but you can see the complete list by using the console command "vid_describemodes"
	- number of listed video modes in the "video options" menu increased from 27 to 36.
	- added alpha control for the front sky layer. (see cvar "r_skyalpha")
	- clock can now display time in 24-hour or "military" time.
	- added an "mtex" counter to the r_speeds 2 readout.  This measures the number of megabytes of texture memory used each frame to draw the scene. Note: this doesn't count textures used to draw the console, menu, or statusbar.
	- added optional drawing of surfaces inside sky leaves, for compiler/map testing purposes.  (see cvar "r_oldskyleaf")
	- sky surfaces on bmodels are now visible, though drawn incorrectly.
	- fixed multiple textures in bsp with same name or no name get overwritten/not loaded. (example: rd1m3)
	- fixed some nasty texture loading bugs that were especially hounding 3dfx users (wrong texture, no texture, or unnecessarily low-res textures displayed on models and world.)  These bugs would also occur in conjunction with nonzero values of gl_max_size or gl_picmip.
	- fixed bug where changing gl_max_size or gl_picmip in-game would screw up alias model texture coordinates.
	- fixed bug where if -gamma is specified at the command line, the "gamma" cvar would be ignored.
	- fixed model more than 2048 units above floor us unlit by static lighting.
	- fixed crash with con_logcenterprint when centerprint message was too long.
	- fixed crash when changing to a nonexistant gamedir and then trying to write a file (screenshot, etc.)  Fitzquake now creates the directory as needed.
	- fixed "bad surface extents" error when sky or water surface is missing from bsp file.
	- fixed alias model shadows write to z-buffer.
	- fixed underwater intermission camera has warp, but no screenblend.
	- fixed console buffer still scrolled back after using the "clear" command.
	- fixed console command history (the list of previous commands) not being rewound after toggling the console.
	- removed cvar gl_texsort. New bsp drawing code always sorts by texture.
	- removed cvar gl_ztrick. The depth buffer is now cleared every frame.
	- removed cvar gl_keeptjunctions.  Extra verts created by qbsp to eliminate tjunctions are now always kept.
	- removed "sliding on monsters' heads" fix, becuase I decided I don't like the idea of changing gameplay, even if the original behaviour is clearly a bug.  Since this bug can be fixed in quakec also, I feel safer leaving it as it was.
	
cvars:

	- gl_overbright. default 1. This variable controls overbright lighting on the world polygons.  (For lighting on models, use gl_overbright_models.)  If 1, overbright will be enabled and lighting will resemble software Quake.  If 0, overbright will be disabled and lighting will resemble GLQuake.
	
	- r_oldskyleaf. default 0.  If 0, surfaces inside sky leaves will be skipped by the renderer.  If 1, they will be drawn whenever they are in your PVS, just like any other surface.
	
	- r_oldwater. default 1. If 1, use the old GLQuake method of subdividing the water surface to enable a warping animation.  If 0, use the new render-to-texture method.  Note: in general, r_oldwater 0 looks better and runs slower.  So experiment to see if the performance hit is acceptable to you.

	- r_skyalpha. default 1.  Sets the alpha of the front sky layer. Note that if sky alpha is less than 1.0, the sky will be drawn in two passes even if you have multitexture.

	- r_waterquality. default 8. Sets the quality of the water when r_oldwater is 0. Can be anywhere from 1 to 64.  Lower values give better performance, higher values look better.  A value of 4 will provide water that looks at least as good as glquake can get, and 32 is close enough to software quake for all but the most picky.  To control the quality of water when r_oldwater is 1, use gl_subdivide_size instead.

	- scr_clock. default 0. If 1, game time is displayed. If 2, system time is displayed in 12-hour format. If 3, system time will be displayed in 24-hour or "military" time.

Changes in 0.70
---------------

	- added anaglyph stereo rendering.  Note that this will cut your framerate in half, as it is rendering the scene once for each eye.  You might want to turn off r_drawviewmodel as it is hard to focus on becuase it is so close.  (see cvars "r_stereo", "r_stereodepth")
	- now uses ARB_multitexture if present, otherwise tries to use SGIS_multitexture.  This should fix various blending bugs on some cards, such as weird cloud layers, all-black models, and inverted torches. (only ARB guarantees that GL_DECAL blending will work)
	- overbright models now uses GL_EXT_texture_env_combine if supported (TNT and later, voodoo4 and later,) which saves one or two passes on model rendering when gl_overbright_models is 1. The command line option -nocombine will disable this.
	- gl_overbright_models now defaults to 1
	- custom palettes are now correctly loaded when you use the "game" command.
	- RecursiveLightPoint is now lerped for smoother lighting of slow-moving models.  Check out the ogre in e3m3 for an example.
	- dynamic lighting (rockets, etc) has been moderately sped up. (some lightmaps were being uploaded even though they weren't actually touched by a dynamic light.)
	- overhauled 2d drawing to allow independent scaling of console, menu, and sbar (see cvars "scr_conwdith," "scr_menuscale," and "scr_sbarscale")  command line switches "-conwidth" and "-conheight" removed.  cvar "scr_stretch_menus" removed.
	- user control of max framerate. (see cvar "host_maxfps")
	- improved the accuracy of the FPS counter a bit, but it still seems suspect.
	- particles can now be drawn as quads or triangles. (see cvar "r_quadparticles")
	- opengl information (vendor, renderer, version, extensions) is no longer printed during initialization. (see command "gl_info")
	- rewrote texture management.  Now instead of quake's memory usage going up and up forever (becuase textures were uploaded to the opengl.dll and never freed,) all textures will get flushed when you switch games, bringing you back down to where you were when fitzquake first launched.
	- gl_texturemode command will now accept a number (1 through 6) as well as the name (gl_linear_mipmap_nearest, etc.)
	- gl_describetexturemodes will list all texturemodes.
	- the inside of sky leaves are no longer rendered -- so when noclipping inside them, it will look the same as noclipping inside a solid wall. This does not affect gameplay.
	- cleaned up intermission display in singleplayer -- no more overlapping numbers
	- r_speeds readout modified a bit. (see cvar "r_speeds")
	- r_sky_quality now defaults to 12 instead of 8, since skies are now drawn in 1 pass (with multitexture at least)
	- gl_texsort now always defaults to 0. (it used to be forced to 1 when multitexture was unavailable)
	- fixed bug where models would actually darken when dlights got bright enough
	- fixed deathmatch, coop cvars not reset to zero when starting a new game from the single player menu
	- fixed r_lightmap doesn't work when gl_texsort = 0.
	- fixed inverted lightmaps / no textures / no dynamic light bug when multitexture is disabled and gl_texsort = 0
	- fixed scrolling map title in wrong place when width does not equal conwidth
	- fixed a few color borking problems in 16-bit mode.  The front sky layer, sprites, and pics with transparency will still look a bit off (as in glquake,) but at least the console image and statusbar background look better.  Though it isn't perfect, it should once again look like what you expect from glquake in 16bit.
	- fixed pixel gap on both sides of the console in 1024x768
	- fixed wpoly count being slightly lower when gl_texsort = 0 (the count was correct when gl_texsort = 1)
	- fixed lmap count always zero when gl_texsort = 1
	- dlight fans are now drawn after water, so that it looks right at least when wateralpha is 1.
	- fixed a possible bug with older 3dfx cards (voodoo 1/2/rush) where the gamma cvar might not work (untested)
	- fixed old commands showing up in the console prompt after hitting 'enter'
	- increased MAX_HANDLES so that you should never see the "out of handles" error message.
	- removed cvar "chase_alpha."  the transparent player model was buggy and didn't work well in a lot of conditions.
	- removed cvar "gl_doubleeys" (yes, that is the correct misspelling)  With overbright models, eyes can be seen as easily as in software mode.
	- removed cvars "cl_crossx," "cl_crossy," "lcd_x," "lcd_yaw," and "gl_reporttjunctions" which didn't do anything (in glquake, at least).
	- removed support for GL_EXT_shared_texture_palette (special 8-bit texture format)
	- removed VCR code.  command line switches "-record" and "-playback" no longer supported.
	- removed support for command line switch "-gamma" -- just use the gamma cvar, or idgamma or something.
	
cvars:

	- r_stereo. default 0.  If nonzero, the scene will be rendered once in red, and again in cyan, with the two views shifted slightly.  If you have 3D glasses you can appreciate this (assumes that the left eye is red and the right eye is cyan.)  The value of r_stereo sets the eye separation.  If your glasses have red on the right eye, use a negative value to flip the views.
	
	- r_stereodepth. default 128.  Sets the distance at which the two views will converge when stereo rendering is active.
	
	- scr_conwdith. default 0.  Sets the virtual console width, where smaller numbers means larger text.  Values larger than window width, or smaller than 320, will be clamped to that range, and all values will be rounded to a multiple of 8.  If 0, the window width will be used.  Note that values that divide evenly into the window width will make the text look nicest.
	
	- scr_menuscale. default 1.  Sets the scale factor for menus and other centered overlays.  If 1, images will be drawn at 1:1 scale.  If 2, images will be double size.  Menus will never be drawn smaller than 1:1, and never larger than the size of the window.  Note that integer values will make the text look nicest.
	
	- scr_sbarscale. default 1.  Sets the scale factor for the statusbar.  If 1, images will be drawn at 1:1 scale.  If 2, images will be double size.  The statusbar will never be drawn smaller than 1:1, and never larger than the width of the window.  Note that integer values will make the text look nicest.
	
	- host_maxfps. default 72.  sets the maximum frames per second fitzquake will render (also the maximum number of server frames per second.)  Clamped to the range 10 - 1000.  Set to 72 to mimic standard quake.
	
	- r_quadparticles. default 1.  If 1, particles are drawn as GL_QUADS instead of GL_TRIANGLES.  Quads use 4 verts instead of 3, but the fillrate cost is 1/2 that of triangles. Depending on your card, either one may be faster. This cvar has no effect on the appearance of particles.
	
	- r_speeds. default 0.  Values of 1 and 2 will give you increasing amounts of information.  When you see two numbers separated by a slash, the first number is polys, and the second number is passes.
	
commands:

	- gl_info.  Displays opengl info which was previously displayed during initialization: vendor, renderer, version, and extensions
	
	- imagelist.  Displays a list of loaded textures, and their dimentions.
	
	- gl_texturemode.  Now accepts a number (1 through 6) as well as the name (gl_nearest, etc.)
	
	- gl_describetexturemodes.  Lists all texturemodes.

Changes in 0.65
---------------

	- gamma cvar now supported. (see cvar "gamma")
	- fullbrights on models now supported.
	- odd-sized world textures are now bilinearly resampled (instead of glquake's nearest pixel resample)
	- removed all fixed-size buffers for loading textures; now the only limit is the size of your memory heap (textures will still be downsampled if they are bigger than the hardware can handle)
	- styled lights (torch flicker, etc.) can now be disabled (see cvar "r_flatlightstyles")
	- sky now uses multitexture if available.
	- centerprints are now optionally logged to the console (see cvar "con_logcenterprint")
	- number of savegame slots increased to 20 (from 12)
	- if a map title is longer than 22 characters, it scrolls marquee-style in the statusbar.
	- gl_flashblend defaults to 1 again. (consistency with glquake)
	- gl_ztrick defaults to 1 again. (consistency with glquake)
	- command line gamma now defaults to 1.0 for all cards. (consistency with glquake, plus hardware gamma is better)
	- now checks hardware for maximum texture size. Users of later voodoo cards should be able to see large textures now. (see cvar "gl_max_size")
	- now shows AM/PM when scr_clock is 2
	- fixed crash when starting dedicated server
	- fixed crash when loading too many textures. (now it throws a sys_error and quits)
	- fixed fitzquake-specific crash when player goes near water in a demo playback.
	- scr_conalpha now actually works.
	- keypad enter in the console works again.
	- optional 2x overbrightening on models. (see cvar "gl_overbright_models")
	- optional quake2-style noclip. (see cvar "sv_altnoclip")
	- new icon
	
cvars:

	- con_logcenterprint: If 1, centerprint messages will be logged to the console in sp/coop. If 2, they will also be logged in deathmatch. Default 1.

	- gamma: Brighten or darken the screen to compensate for differences between monitors. This is now supported by using your video card's gamma support. Just like in winquake, values less than 1 are brighter and values greater than one are darker. Default 1. Notes: I have added special code so that this will work on 3dfx cards too, but i have no way to check that it works. If fitzquake crashes, your hardware gamma may be stuck at the wrong value. You can use the "display settings" control panel fix this, or you could try lordhavoc's useful "setgamma" utility (available on this page.) Also note that if texture-brightening gamma has been requested at the command line (fitzquake.exe -gamma ), harware gamma will not be used and the gamma cvar will have no effect.

	- gl_max_size: Now defaults to 0. If 0, textures will be as large as the hardware allows. Positive values can be used to impose a limit smaller than the hardware's reported maximum.

	- gl_overbright_models: If 1, models will be rendered using 2x overbrightening and will appear at roughly the same brightness as they do in software quake, which is noticably brighter than the default fitzquake / glquake appearance. I disabled this cvar by default becuase this is still a poorly supported feature -- it currently takes 2 or 3 passes to render a model when this feature is enabled, compared to only 1 pass when it is disabled. Default 0.

	- r_flatlightstyles: If 1, styled lights (torch flicker, etc.) will be displayed as a steady light. If 2, the peak intensity will be used instead of the average intensity. Default 0.

	- sv_altnoclip: If 1, enable the alternative noclip movement which resembles quake2 and is not constrained to the horizontal plane. Set to 0 to retain quake's original noclip behavior. Default 1.

		- r_novis changes now take effect immediately, rather than when you cross a leaf boundary
		- removed mirror code
		- two particle styles, circle and square (cvar controlled)
	- console:
		- improved tab completion:
			- hitting tab once will display a list of possible matches and complete the line using the first match
			- hitting tab or shift-tab will cycle through the matches
			- autocomplete will now match against aliases as well as commands and cvars.
			- autocomplete will now complete later in the string (e.g. "bind mouse1 +att" + tab will complete '+attack')
			- autocomplete will even complete inside the string (e.g. "bind m +attack" + tab will complete 'mouse1' if the cursor is right after the 'm')
		- new key functionality:
			- tab -- autocomplete, cycle through multiple matches
			- shift-tab -- cycle backwards through multiple matches
			- ins -- toggle insertmode
			- del -- delete current character
			- backspace -- delete previous character
			- ctrl-v -- paste from windows clippboard

		- quadrupled the length of the console history
	- commands: 
		- "game " to load a mod.

		- resetall. resets all cvars.
		- mods. lists all child folders of quake directory which contain either a progs.dat or a pak file
		- maps. lists all addon levels available (i.e. all levels that are not in id1/*.pak)
		- mapname. outputs the short name of the current level (e.g. "e1m5")
		- cmdlist. alphabetized. 'cmdlist blah' will list only cmds that start with 'blah'
		- cvarlist. alphabetized. 'cvarlist blah' will list only cvars that start with 'blah'
		- "inc  [amount]" to increment a cvar by amount. amount defaults to 1.
		- "toggle " to invert the value of a cvar (nonzero -> 0 and 0 -> 1)
		- god, noclip, notarget, and fly can now be explicitly set. example: "god 0" will disable god mode
		- viewpos. outputs (X,Y,Z) pitch yaw roll
		- "give a " now gives you armour. type depends on value
		- bindlist. lists all key bindings

		- condump. dumps console to condump.txt
		- fog. set global fog. syntax is "fog ", "fog   ", or "fog    "  See section on modding for details. Set density to 0 to disable fog.
		- "sky " to load a skybox. if skyname is "", this will turn off skybox rendering.
		- stuffcmds now parses the "cmdline" cvar rather than the args actually passed to the program.  This is useful for loading mods dynamically, so you can edit the cmdline before execing quake.rc (which calls "stuffcmds")
	- cvars:
		- scr_stretch_menus. default 1. if 1, menus and other overlays are stretched to fill the screen
		- scr_conalpha. default 1. This is the opacity when the console is halfscreen. 0.6 will mimic glquake
		- scr_clock. default 0. if 1, game time is displayed. If 2, system time is displayed.
		- scr_showfps. default 0. if 1, FPS are displayed.
		- r_waterwarp recognized. default 1. if zero, no underwater warping will take place
		- r_drawflat recognized. default 0. if 1, polygons will be drawn as a solid color with no lightmap or texture
		- r_particles. default 1. 0 = no particles, 1 = circular particles, 2 = square particles
		- r_fastsky. default 0. if 1, sky will be rendered as solid color, for added performance
		- r_sky_quality. default 8.  Higher number divides the sky more, for a smoother effect and slower performance.
		- r_clearcolor now supported. default 2.  specify a palette index from 0 to 255.
		- gl_fullbrights. default 1. set to 0 to disable fullbrights
		- gl_farclip. default 8192.  set to 4096 to mimic glquake.  note that the skybox will be drawn somewhat closer than this value.
		- cl_maxpitch. default 90 (straight down.) set to 80 to mimic normal quake
		- cl_minpitch. default -90 (straight up.) set to -70 to mimic normal quake
		- cl_keypad. default 1.  if 0, keypad keys will respond as in quake.exe (for example, pushing 'KP_END' will be the same as pushing '1')
		- gl_flashblend now defaults to 0.
		- gl_ztrick now defaults to 0.
		- gl_keeptjunctions now defaults to 1. (note, contrary to the name of this cvar, what is being kept is the extra polygon verts which *eliminate* tjunctions. This is a good thing, so i made it default to 1)
		- chase_alpha. default 1.  lower values make the chasecam player model translucent. Buggy.
	- keyboard
		- keypad keys are now bindable:
			KP_NUMLOCK, KP_SLASH, KP_STAR, KP_MINUS, KP_HOME, KP_UPARROW, KP_PGUP, KP_PLUS, KP_LEFTARROW, KP_5, KP_RIGHTARROW, KP_END, KP_DOWNARROW, KP_PGDN, KP_ENTER, KP_INS, KP_DEL
	- command line:
		- running with -gamma at the command line will set the gamma.  There is still no way to change this value in  game.  Default is 1.0 for 3dfx cards, 0.7 for all others
		- if unspecified, -conwidth now defaults to -width
	- modding extensions:
		- skyboxes (worldspawn and qc settable), currently only targa and pcx formats accepted
		- global fog (worldspawn and qc settable)
	- physics
		- fixed sliding around while standing on solid entities' bounding boxes (monsters, players, etc)
	- misc
		- default heapsize is now 32mb (was 16mb)
		- default zonesize is now 256k (was 48k)

Fitzquake version 0.80, May 26, 2005 

Filename                : fitzquake080.exe

Fitzquake is a modified glquake based on the source code released by id 
Software. My primary focus is fixing a lot of the rendering bugs which made 
glquake inferior to the software renderer. My secondary focus is adding 
conveniences for mappers and general users. I am also slowly adding support for
new modding or mapping features such as skyboxes, fog, and colored light. 

While I have made extensive changes to the code, I pretty much use the same 
OpenGL features that the original glquake uses. Therefore, if you can run 
glquake, you can probably run Fitzquake. 

I am not finished working on this project, so bug reports and feature requests
are welcome.

History
================================================================================

changes in 0.80
---------------

	- map loading is about four times faster.  This is due to some optimizations in the texture loading code.
	- video mode can now be changed in-game.  You can change resolution, color depth, refresh rate, and switch between windowed and fullscreen modes.  This can be accomplished easily using the video options menu, and is also available at the console using cvars. Note: if you launch fitzquake with -width, -height, -window, or -bpp in the command line, Fitzquake will use the command line settings and ignore whatever it reads from the config files at startup. However, you will still be able to change the video mode from the menu or the console as you like. Also note: to change video modes by execing a config file, the config file must include "vid_restart" after the other vid_ cvars have been set. (see cvars "vid_width," "vid_height," "vid_fullscreen," "vid_bpp," "vid_refreshrate," and commands "vid_restart," "vid_test")
	- added control of entity count limits (MAX_EDICTS.)  The default maximum has been increased from 600 to 1024.  It can be raised even higher (up to 8192 -- this is a limit set by the network protocol) using a cvar. (see cvar "max_edicts")
	- added control of vertical sync.  (see cvar "vid_vsync")
	- added control of anistropic filtering.  Anisotropic filtering is a method to improve texture clarity on surfaces when viewed at steep angles.  (see cvar "gl_texture_anisotropy")
	- console buffer size can now be set.  The command line option "-consize" allows you to specify the buffer size in kilobytes.  For reference, fitzquake's default buffer size is 64k, and glquake's is 16k.  16k is also the smallest size fitzquake will allow you to set.  Note: this buffer lives in the heap, so if you want to have a HUGE buffer, you might need to increase -heapsize also.
	- increased max surface extents from 256 (the software quake maximum) to 2000.  For reference, the glquake maximum is 512.  This should eliminate the "bad surface extents" crash when running some maps that could be played in glquake, but not fitzquake or winquake.
	- increased max vertices in an alias model from 1024 (the glquake maximum) to 2000 (the software quake maximum.)
	- increased MAX_CHANNELS from 128 to 512 and MAX_DYNAMIC_CHANNELS from 8 to 128
	- screenshot filenames are now in the format "fitz0000.tga", increasing the maximum number of screenshots per folder from one hundred to ten thousand.
	- vid_describemodes output cleaned up; now displays a list of valid refresh rates for each mode
	- added a more intuitive cvar control of slow motion/fast-forward for demos and live gameplay.  (see cvar "host_timescale")
	- "reset to defaults" option in the menu now executes the "resetall" command before loading default.cfg
	- game command now writes config.cfg to current gamedir before switching
	- +mlook is now saved to config.cfg
	- changed smallest allowed window size from 320x240 to 320x200
	- console cursor images are now hard-coded, and the insert mode cursor is now a vertical bar instead of an underscore. This was prompted by several popular mods (OUM, Xmen TC) using nonstandard cursors, which are incompatible the fitzquake console enhancements.
	- gl_farclip now defaults to 16384.  This should be high enough to handle even the largest open areas without unwanted clipping.  The only reason you'd want to lower this number is if you see z-fighting.
	- added cvar r_drawworld (see below)
	- added cvar r_showtris (see below)
	- added cvar r_showbboxes (see below)
	- added a command to cycle a cvar through a list of values. (see command "cycle")
	- mapname command now works on dedicated server.
	- added a hack to fix those white edges on the bottom of the large box of shells.  I feel dirty, but they look better, now.
	- changed stuffcmds behavior to allow hyphenated map names, config file names, etc. in the command line. (example: "fitzquake.exe +exec my-config.cfg +map my-map")  However, you still can't load a map or config file when the first character in the filename is a hyphen.
	- skybox loader now reverts to scrolling sky if all 6 skybox faces failed to load.
	- tweaked circular particles to match the apparent size of the square particles.
	- fixed crash when loading mods with large player skins (like the chainsaw mod, and PerQuake.)  Colormapping can now handle any size player texture (limited to the heapsize, of course.)
	- fixed bug where a replacement model in a mod is messed up becuase a matching .ms2 file in id1/glquake is present.  The fix is simply to disable all mesh caching, which slows down model loading a little.
	- fixed freeze when gl_overbright is 1 and either texture_env_combine or multitexture is disabled or not supported.
	- fixed "numgltextures == MAX_GLTEXTURES" crash when viewing multiplayer->setup menu.
	- fixed "numgltextures == MAX_GLTEXTURES" crash when playing large maps (nesp09,) due to frequent model recaches.
	- fixed bug where entities and water were not being drawn any frame in which a model had to be recached.
	- fixed skybox texture showing up in the place of other textures/skins/lightmaps, when the previous loaded map had a skybox.
	- fixed missing polygons on edges of screen when underwater and r_waterwarp is 1.
	- fixed missing polygons on edges of screen when r_stereo is enabled.
	- fixed long mapnames that scroll are truncated to be shorter than what appears in the console.  Well, sort of.  What I did was increase the maximum length from 39 to 127.  A mapname longer than 127 will still be truncated, but these are pretty rare.
	- fixed rogue's teamplay skin showing up as an all-white texture.
	- fixed checkerboard texture shows up sometimes when an animated texture has fullbright pixels on some frames, but not others (reactor core in junk.bsp)
	- fixed color 255 is not fullbright
	- fixed fuscia dots appearing in corners of resampled textures
	- fixed mapname command crashes when client is disconnected.
	- fixed cl_nolerp 1 screws up speed of demo playback
	- fixed annoying client-side step-up smoothing when in noclip mode (except on nonlocal servers.)
	- fixed scr_clock 2 displays hour twelve as "0" instead of "12"
	- fixed skip textured surfaces still drawn even after running tyrann's skip utility
	- fixed crash when loading a map with a sky texture where the "sky" in the texturename is not lowercase
	- fixed hang in e2m2 on easy skill, where you can shoot one of the buttons at the beginning and then trick-jump through the open gate.  Now it prints a warning message ("SV_TouchLinks: null link") and lets you keep playing.
	- fixed bug when viewsize < 100, and r_oldwater is 0, where you can see the water textures overlaying part of the brown frame around the viewport.
	- fixed bug where imagelist and r_speeds2 would report the same megabyte counts in both 16bpp and 32bpp mode, even though texture bpp should match (and does match) framebuffer bpp.  The numbers are now different and accurate for each bit depth.
	- removed cvars "vid_config_x," "vid_config_y," "vid_wait," "vid_nopageflip," "_vid_wait_override," "_vid_default_mode," "_vid_default_mode_win," and "vid_stretch_by_2," none of which glquake ever used.
	- removed cvar "vid_mode" and commands "vid_describemode" and "vid_nummodes," because of the new video mode handling.
	
cvars:

	- gl_texture_anisotropy. Controls the amount of anisotropy in texture filtering.  If 1 or less than 1, texture filtering is normal (isotropic.)  If greater than 1, increasing degrees of anisotropic filtering are used, up to the hardware maximum. Set value to 2 for 2x anisotropic, 4 for 4x, etc. Default 1.

	- host_timescale.  Scales the passage of time on client and server. Set to 0 or 1 for normal speed, less than 1 for slow motion, and greater than 1 for fast-forward.  If greater than 0, overrides host_framerate.  Default 0.
	
	- max_edicts. Sets the maximum number of entites on both the client and server. Default 1024. Acceptable values range from 256 to 8192. Set to 600 to mimic standard quake. Changes won't take effect until the next time a map is loaded. Note: if a client connects to a server, and the client's maximum is lower than the server's, the client will probably crash if it ever sees an entnum higher than its local max_edicts. Warning: you may need to increase -heapsize if you want a high max_edicts value.
	
	- r_drawworld. If 1, draw world as usual.  If 0, don't draw the world.  Default 1. (compare r_drawentities)
	
	- r_showbboxes. If 1, draw a wireframe bounding box around each entity.  Note that these are the server-side per-edict physics bounding boxes, not the client-side per-model rendering bboxes. If 0, disable this feature. Default 0.
	
	- r_showtris. If 1, draw wireframe outlines for every triangle in the scene. Like in Quake 3, the lines will be visible even through solid geometry.  If 2, draw the outlines only on visible surfaces (like r_showtris 2 in Medal of Honor.) If 0, disable wireframe overlay.  Default 0.
	
	- vid_bpp. Sets the color depth of the screen in fullscreen mode. Windowed mode ignores this setting. Can be 16 or 32. Default 16. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_fullscreen. If 1, fitzquake will run fullscreen. If 0, fitzquake will run in a window. Default 1. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_height. Sets the vertical screen/window resolution. Default 480. In windowed mode, cannot be less than 200. (Changes won't take effect until the next call to vid_restart.)
	
	- vid_refreshrate. Sets the refresh rate of the screen in fullscreen mode. Windowed mode ignores this setting. Possible values include 60, 70, 72, 75, 85, etc.  Default 60. (Changes won't take effect until the next call to vid_restart.)

	- vid_width. Sets the horizontal screen/window resolution. Default 640. In windowed mode, cannot be less than 320. (Changes won't take effect until the next call to vid_restart.)

	- vid_vsync.  Set to 1 to enable vertical sync, which eliminates tearing, but caps your framerate at the monitor refreshrate.  Set to 0 to disable vertical sync, which allows tearing but doesn't cap your framerate. Default 0.  Note: If fitzquake detects that your driver settings have forced vsync to be disabled, it will post a message to the console saying so, and this cvar will have no effect.

commands:

	- "cycle   [ [ ...]]" to cycle a cvar through a list of values..  Note: this command will get stuck on a list that contains the same value more than once, such as "cycle blah 1 2 1 3". If you're doing anything that complex you can just use aliases.

	- vid_restart.  Tries to set a video mode that matches the values of vid_width, vid_height, vid_fullscreen, and, if vid_fullscreen is 1, vid_bpp and vid_refreshrate.
	
	- vid_test. Like vid_restart, except that after switching to the new mode pops up a confirmation dialogue.  This is useful if you are not sure what modes your monitor can handle, so you don't get stuck with a blank screen.  The dialogue has a time limit so that if you don't press a key within 5 seconds, it will revert to the previous mode.

changes in 0.75
---------------

	- totally rewritten bsp drawing code.  The new code combines the advantages of the gl_texsort 1 and gl_texsort 0 codepaths from glquake into one codepath that uses texture sorting and multitexture.  In my tests, i've found that it's about the same speed as glquake in low poly scenes (like the original quake levels,) but as you get into the thousands of wpolys, it's faster and faster.
	- 2x overbright lighting.  Lighting now looks like software quake.  Just like overbright lighting on models, overbright on world polys requires GL_EXT_texture_env_combine (TNT and later, voodoo4 and later.)  Without it, FitzQuake will be use two passes to render overbright world polys.  So if you don't have that extension, you might disable it for performance reasons.  (see cvar "gl_overbright")
	- colored lighting support using .lit files.
	- totally new water surface animation.  The new method requires no surface subdivision, isn't plagued by tearing and sparklies caused by tjunctions, and looks almost identical to software quake's water, and doesn't slow down on very large sheets of water. (see cvars "r_waterquality" and "r_oldwater")
	- old water aninmation fixed so that it doesn't look bad when gl_subdivide_size is 32 or lower.
	- can load external textures (currently targa and pcx) if they match the texture name in the bsp and are located in the id1/textures, or /textures directory.  At the moment no other images (skins, menu, etc.) can be replaced.
	- gamma correction now goes back to normal when Fitzquake loses focus.
	- tab completion now adds a space after the completed command/cvar if the cursor is at the end of the editline.
	- increased the max length of the video mode list from 30 to 80.  This should alleviate the problems people with newer cards were having trying to use some 32-bit modes -- there were so many 16-bit modes that they filled up the list before all 32-bit modes could be detected.  The video menu will still only list a certain number of modes due to space constraints, but you can see the complete list by using the console command "vid_describemodes"
	- number of listed video modes in the "video options" menu increased from 27 to 36.
	- added alpha control for the front sky layer. (see cvar "r_skyalpha")
	- clock can now display time in 24-hour or "military" time.
	- added an "mtex" counter to the r_speeds 2 readout.  This measures the number of megabytes of texture memory used each frame to draw the scene. Note: this doesn't count textures used to draw the console, menu, or statusbar.
	- added optional drawing of surfaces inside sky leaves, for compiler/map testing purposes.  (see cvar "r_oldskyleaf")
	- sky surfaces on bmodels are now visible, though drawn incorrectly.
	- fixed multiple textures in bsp with same name or no name get overwritten/not loaded. (example: rd1m3)
	- fixed some nasty texture loading bugs that were especially hounding 3dfx users (wrong texture, no texture, or unnecessarily low-res textures displayed on models and world.)  These bugs would also occur in conjunction with nonzero values of gl_max_size or gl_picmip.
	- fixed bug where changing gl_max_size or gl_picmip in-game would screw up alias model texture coordinates.
	- fixed bug where if -gamma is specified at the command line, the "gamma" cvar would be ignored.
	- fixed model more than 2048 units above floor us unlit by static lighting.
	- fixed crash with con_logcenterprint when centerprint message was too long.
	- fixed crash when changing to a nonexistant gamedir and then trying to write a file (screenshot, etc.)  Fitzquake now creates the directory as needed.
	- fixed "bad surface extents" error when sky or water surface is missing from bsp file.
	- fixed alias model shadows write to z-buffer.
	- fixed underwater intermission camera has warp, but no screenblend.
	- fixed console buffer still scrolled back after using the "clear" command.
	- fixed console command history (the list of previous commands) not being rewound after toggling the console.
	- removed cvar gl_texsort. New bsp drawing code always sorts by texture.
	- removed cvar gl_ztrick. The depth buffer is now cleared every frame.
	- removed cvar gl_keeptjunctions.  Extra verts created by qbsp to eliminate tjunctions are now always kept.
	- removed "sliding on monsters' heads" fix, becuase I decided I don't like the idea of changing gameplay, even if the original behaviour is clearly a bug.  Since this bug can be fixed in quakec also, I feel safer leaving it as it was.
	
cvars:

	- gl_overbright. default 1. This variable controls overbright lighting on the world polygons.  (For lighting on models, use gl_overbright_models.)  If 1, overbright will be enabled and lighting will resemble software Quake.  If 0, overbright will be disabled and lighting will resemble GLQuake.
	
	- r_oldskyleaf. default 0.  If 0, surfaces inside sky leaves will be skipped by the renderer.  If 1, they will be drawn whenever they are in your PVS, just like any other surface.
	
	- r_oldwater. default 1. If 1, use the old GLQuake method of subdividing the water surface to enable a warping animation.  If 0, use the new render-to-texture method.  Note: in general, r_oldwater 0 looks better and runs slower.  So experiment to see if the performance hit is acceptable to you.

	- r_skyalpha. default 1.  Sets the alpha of the front sky layer. Note that if sky alpha is less than 1.0, the sky will be drawn in two passes even if you have multitexture.

	- r_waterquality. default 8. Sets the quality of the water when r_oldwater is 0. Can be anywhere from 1 to 64.  Lower values give better performance, higher values look better.  A value of 4 will provide water that looks at least as good as glquake can get, and 32 is close enough to software quake for all but the most picky.  To control the quality of water when r_oldwater is 1, use gl_subdivide_size instead.

	- scr_clock. default 0. If 1, game time is displayed. If 2, system time is displayed in 12-hour format. If 3, system time will be displayed in 24-hour or "military" time.

Changes in 0.70
---------------

	- added anaglyph stereo rendering.  Note that this will cut your framerate in half, as it is rendering the scene once for each eye.  You might want to turn off r_drawviewmodel as it is hard to focus on becuase it is so close.  (see cvars "r_stereo", "r_stereodepth")
	- now uses ARB_multitexture if present, otherwise tries to use SGIS_multitexture.  This should fix various blending bugs on some cards, such as weird cloud layers, all-black models, and inverted torches. (only ARB guarantees that GL_DECAL blending will work)
	- overbright models now uses GL_EXT_texture_env_combine if supported (TNT and later, voodoo4 and later,) which saves one or two passes on model rendering when gl_overbright_models is 1. The command line option -nocombine will disable this.
	- gl_overbright_models now defaults to 1
	- custom palettes are now correctly loaded when you use the "game" command.
	- RecursiveLightPoint is now lerped for smoother lighting of slow-moving models.  Check out the ogre in e3m3 for an example.
	- dynamic lighting (rockets, etc) has been moderately sped up. (some lightmaps were being uploaded even though they weren't actually touched by a dynamic light.)
	- overhauled 2d drawing to allow independent scaling of console, menu, and sbar (see cvars "scr_conwdith," "scr_menuscale," and "scr_sbarscale")  command line switches "-conwidth" and "-conheight" removed.  cvar "scr_stretch_menus" removed.
	- user control of max framerate. (see cvar "host_maxfps")
	- improved the accuracy of the FPS counter a bit, but it still seems suspect.
	- particles can now be drawn as quads or triangles. (see cvar "r_quadparticles")
	- opengl information (vendor, renderer, version, extensions) is no longer printed during initialization. (see command "gl_info")
	- rewrote texture management.  Now instead of quake's memory usage going up and up forever (becuase textures were uploaded to the opengl.dll and never freed,) all textures will get flushed when you switch games, bringing you back down to where you were when fitzquake first launched.
	- gl_texturemode command will now accept a number (1 through 6) as well as the name (gl_linear_mipmap_nearest, etc.)
	- gl_describetexturemodes will list all texturemodes.
	- the inside of sky leaves are no longer rendered -- so when noclipping inside them, it will look the same as noclipping inside a solid wall. This does not affect gameplay.
	- cleaned up intermission display in singleplayer -- no more overlapping numbers
	- r_speeds readout modified a bit. (see cvar "r_speeds")
	- r_sky_quality now defaults to 12 instead of 8, since skies are now drawn in 1 pass (with multitexture at least)
	- gl_texsort now always defaults to 0. (it used to be forced to 1 when multitexture was unavailable)
	- fixed bug where models would actually darken when dlights got bright enough
	- fixed deathmatch, coop cvars not reset to zero when starting a new game from the single player menu
	- fixed r_lightmap doesn't work when gl_texsort = 0.
	- fixed inverted lightmaps / no textures / no dynamic light bug when multitexture is disabled and gl_texsort = 0
	- fixed scrolling map title in wrong place when width does not equal conwidth
	- fixed a few color borking problems in 16-bit mode.  The front sky layer, sprites, and pics with transparency will still look a bit off (as in glquake,) but at least the console image and statusbar background look better.  Though it isn't perfect, it should once again look like what you expect from glquake in 16bit.
	- fixed pixel gap on both sides of the console in 1024x768
	- fixed wpoly count being slightly lower when gl_texsort = 0 (the count was correct when gl_texsort = 1)
	- fixed lmap count always zero when gl_texsort = 1
	- dlight fans are now drawn after water, so that it looks right at least when wateralpha is 1.
	- fixed a possible bug with older 3dfx cards (voodoo 1/2/rush) where the gamma cvar might not work (untested)
	- fixed old commands showing up in the console prompt after hitting 'enter'
	- increased MAX_HANDLES so that you should never see the "out of handles" error message.
	- removed cvar "chase_alpha."  the transparent player model was buggy and didn't work well in a lot of conditions.
	- removed cvar "gl_doubleeys" (yes, that is the correct misspelling)  With overbright models, eyes can be seen as easily as in software mode.
	- removed cvars "cl_crossx," "cl_crossy," "lcd_x," "lcd_yaw," and "gl_reporttjunctions" which didn't do anything (in glquake, at least).
	- removed support for GL_EXT_shared_texture_palette (special 8-bit texture format)
	- removed VCR code.  command line switches "-record" and "-playback" no longer supported.
	- removed support for command line switch "-gamma" -- just use the gamma cvar, or idgamma or something.
	
cvars:

	- r_stereo. default 0.  If nonzero, the scene will be rendered once in red, and again in cyan, with the two views shifted slightly.  If you have 3D glasses you can appreciate this (assumes that the left eye is red and the right eye is cyan.)  The value of r_stereo sets the eye separation.  If your glasses have red on the right eye, use a negative value to flip the views.
	
	- r_stereodepth. default 128.  Sets the distance at which the two views will converge when stereo rendering is active.
	
	- scr_conwdith. default 0.  Sets the virtual console width, where smaller numbers means larger text.  Values larger than window width, or smaller than 320, will be clamped to that range, and all values will be rounded to a multiple of 8.  If 0, the window width will be used.  Note that values that divide evenly into the window width will make the text look nicest.
	
	- scr_menuscale. default 1.  Sets the scale factor for menus and other centered overlays.  If 1, images will be drawn at 1:1 scale.  If 2, images will be double size.  Menus will never be drawn smaller than 1:1, and never larger than the size of the window.  Note that integer values will make the text look nicest.
	
	- scr_sbarscale. default 1.  Sets the scale factor for the statusbar.  If 1, images will be drawn at 1:1 scale.  If 2, images will be double size.  The statusbar will never be drawn smaller than 1:1, and never larger than the width of the window.  Note that integer values will make the text look nicest.
	
	- host_maxfps. default 72.  sets the maximum frames per second fitzquake will render (also the maximum number of server frames per second.)  Clamped to the range 10 - 1000.  Set to 72 to mimic standard quake.
	
	- r_quadparticles. default 1.  If 1, particles are drawn as GL_QUADS instead of GL_TRIANGLES.  Quads use 4 verts instead of 3, but the fillrate cost is 1/2 that of triangles. Depending on your card, either one may be faster. This cvar has no effect on the appearance of particles.
	
	- r_speeds. default 0.  Values of 1 and 2 will give you increasing amounts of information.  When you see two numbers separated by a slash, the first number is polys, and the second number is passes.
	
commands:

	- gl_info.  Displays opengl info which was previously displayed during initialization: vendor, renderer, version, and extensions
	
	- imagelist.  Displays a list of loaded textures, and their dimentions.
	
	- gl_texturemode.  Now accepts a number (1 through 6) as well as the name (gl_nearest, etc.)
	
	- gl_describetexturemodes.  Lists all texturemodes.

Changes in 0.65
---------------

	- gamma cvar now supported. (see cvar "gamma")
	- fullbrights on models now supported.
	- odd-sized world textures are now bilinearly resampled (instead of glquake's nearest pixel resample)
	- removed all fixed-size buffers for loading textures; now the only limit is the size of your memory heap (textures will still be downsampled if they are bigger than the hardware can handle)
	- styled lights (torch flicker, etc.) can now be disabled (see cvar "r_flatlightstyles")
	- sky now uses multitexture if available.
	- centerprints are now optionally logged to the console (see cvar "con_logcenterprint")
	- number of savegame slots increased to 20 (from 12)
	- if a map title is longer than 22 characters, it scrolls marquee-style in the statusbar.
	- gl_flashblend defaults to 1 again. (consistency with glquake)
	- gl_ztrick defaults to 1 again. (consistency with glquake)
	- command line gamma now defaults to 1.0 for all cards. (consistency with glquake, plus hardware gamma is better)
	- now checks hardware for maximum texture size. Users of later voodoo cards should be able to see large textures now. (see cvar "gl_max_size")
	- now shows AM/PM when scr_clock is 2
	- fixed crash when starting dedicated server
	- fixed crash when loading too many textures. (now it throws a sys_error and quits)
	- fixed fitzquake-specific crash when player goes near water in a demo playback.
	- scr_conalpha now actually works.
	- keypad enter in the console works again.
	- optional 2x overbrightening on models. (see cvar "gl_overbright_models")
	- optional quake2-style noclip. (see cvar "sv_altnoclip")
	- new icon
	
cvars:

	- con_logcenterprint: If 1, centerprint messages will be logged to the console in sp/coop. If 2, they will also be logged in deathmatch. Default 1.

	- gamma: Brighten or darken the screen to compensate for differences between monitors. This is now supported by using your video card's gamma support. Just like in winquake, values less than 1 are brighter and values greater than one are darker. Default 1. Notes: I have added special code so that this will work on 3dfx cards too, but i have no way to check that it works. If fitzquake crashes, your hardware gamma may be stuck at the wrong value. You can use the "display settings" control panel fix this, or you could try lordhavoc's useful "setgamma" utility (available on this page.) Also note that if texture-brightening gamma has been requested at the command line (fitzquake.exe -gamma ), harware gamma will not be used and the gamma cvar will have no effect.

	- gl_max_size: Now defaults to 0. If 0, textures will be as large as the hardware allows. Positive values can be used to impose a limit smaller than the hardware's reported maximum.

	- gl_overbright_models: If 1, models will be rendered using 2x overbrightening and will appear at roughly the same brightness as they do in software quake, which is noticably brighter than the default fitzquake / glquake appearance. I disabled this cvar by default becuase this is still a poorly supported feature -- it currently takes 2 or 3 passes to render a model when this feature is enabled, compared to only 1 pass when it is disabled. Default 0.

	- r_flatlightstyles: If 1, styled lights (torch flicker, etc.) will be displayed as a steady light. If 2, the peak intensity will be used instead of the average intensity. Default 0.

	- sv_altnoclip: If 1, enable the alternative noclip movement which resembles quake2 and is not constrained to the horizontal plane. Set to 0 to retain quake's original noclip behavior. Default 1. 

Changes in 0.60
---------------

		- two particle styles, circle and square (cvar controlled)
	- console:
		- improved tab completion:
			- hitting tab once will display a list of possible matches and complete the line using the first match
			- hitting tab or shift-tab will cycle through the matches
			- autocomplete will now match against aliases as well as commands and cvars.
			- autocomplete will now complete later in the string (e.g. "bind mouse1 +att" + tab will complete '+attack')
			- autocomplete will even complete inside the string (e.g. "bind m +attack" + tab will complete 'mouse1' if the cursor is right after the 'm')
		- new key functionality:
			- tab -- autocomplete, cycle through multiple matches
			- shift-tab -- cycle backwards through multiple matches
			- ins -- toggle insertmode
			- del -- delete current character
			- backspace -- delete previous character
			- ctrl-v -- paste from windows clippboard

			- home -- move cursor to beginning of line
			- end -- move cursor to end of line
			- ctrl-pgup -- scroll up a screen at a time
			- ctrl-pgdn -- scroll down a screen at a time
			- ctrl-home -- scroll to top of console history
			- ctrl-end -- scroll to bottom of console history
		- carets indicate that you are scrolled back, like in quakeworld/quake2
		- left arrow, right arrow, pgup, pgdn keys now auto-repeat
		- quadrupled the length of the console history
	- commands: 
		- "game " to load a mod.
		- "reset " to reset a cvar to default. Note that this is the engine default, not the default.cfg value
		- resetall. resets all cvars.
		- mods. lists all child folders of quake directory which contain either a progs.dat or a pak file
		- maps. lists all addon levels available (i.e. all levels that are not in id1/*.pak)
		- mapname. outputs the short name of the current level (e.g. "e1m5")
		- cmdlist. alphabetized. 'cmdlist blah' will list only cmds that start with 'blah'
		- cvarlist. alphabetized. 'cvarlist blah' will list only cvars that start with 'blah'
		- "inc  [amount]" to increment a cvar by amount. amount defaults to 1.
		- "toggle " to invert the value of a cvar (nonzero -> 0 and 0 -> 1)
		- god, noclip, notarget, and fly can now be explicitly set. example: "god 0" will disable god mode
		- viewpos. outputs (X,Y,Z) pitch yaw roll
		- "give a " now gives you armour. type depends on value

		- "alias " now outputs the current command string
		- "unalias " to delete an alias
		- unaliasall. delete all aliases.
		- condump. dumps console to condump.txt
		- fog. set global fog. syntax is "fog ", "fog   ", or "fog    "  See section on modding for details. Set density to 0 to disable fog.
		- "sky " to load a skybox. if skyname is "", this will turn off skybox rendering.
		- stuffcmds now parses the "cmdline" cvar rather than the args actually passed to the program.  This is useful for loading mods dynamically, so you can edit the cmdline before execing quake.rc (which calls "stuffcmds")
	- cvars:
		- scr_stretch_menus. default 1. if 1, menus and other overlays are stretched to fill the screen
		- scr_conalpha. default 1. This is the opacity when the console is halfscreen. 0.6 will mimic glquake
		- scr_clock. default 0. if 1, game time is displayed. If 2, system time is displayed.
		- scr_showfps. default 0. if 1, FPS are displayed.
		- r_waterwarp recognized. default 1. if zero, no underwater warping will take place
		- r_drawflat recognized. default 0. if 1, polygons will be drawn as a solid color with no lightmap or texture
		- r_particles. default 1. 0 = no particles, 1 = circular particles, 2 = square particles
		- r_fastsky. default 0. if 1, sky will be rendered as solid color, for added performance
		- r_sky_quality. default 8.  Higher number divides the sky more, for a smoother effect and slower performance.
		- r_clearcolor now supported. default 2.  specify a palette index from 0 to 255.
		- gl_fullbrights. default 1. set to 0 to disable fullbrights
		- gl_farclip. default 8192.  set to 4096 to mimic glquake.  note that the skybox will be drawn somewhat closer than this value.
		- cl_maxpitch. default 90 (straight down.) set to 80 to mimic normal quake
		- cl_minpitch. default -90 (straight up.) set to -70 to mimic normal quake
		- cl_keypad. default 1.  if 0, keypad keys will respond as in quake.exe (for example, pushing 'KP_END' will be the same as pushing '1')
		- gl_flashblend now defaults to 0.
		- gl_ztrick now defaults to 0.
		- gl_keeptjunctions now defaults to 1. (note, contrary to the name of this cvar, what is being kept is the extra polygon verts which *eliminate* tjunctions. This is a good thing, so i made it default to 1)
		- chase_alpha. default 1.  lower values make the chasecam player model translucent. Buggy.
	- keyboard
		- keypad keys are now bindable:
			KP_NUMLOCK, KP_SLASH, KP_STAR, KP_MINUS, KP_HOME, KP_UPARROW, KP_PGUP, KP_PLUS, KP_LEFTARROW, KP_5, KP_RIGHTARROW, KP_END, KP_DOWNARROW, KP_PGDN, KP_ENTER, KP_INS, KP_DEL
	- command line:
		- running with -gamma at the command line will set the gamma.  There is still no way to change this value in  game.  Default is 1.0 for 3dfx cards, 0.7 for all others
		- if unspecified, -conwidth now defaults to -width
	- modding extensions:
		- skyboxes (worldspawn and qc settable), currently only targa and pcx formats accepted
		- global fog (worldspawn and qc settable)
	- physics
		- fixed sliding around while standing on solid entities' bounding boxes (monsters, players, etc)
	- misc
		- default heapsize is now 32mb (was 16mb)
		- default zonesize is now 256k (was 48k)

Beta release of an SDL port of Fitzquake version 0.80, July 5, 2008

Author                  : Kristian Duske
Email Address           : deceive.inveigle.obfuscate@gmail.com
Author's Homepage       : http://www.kristianduske.com/fitzquake
Minimum SDL version     : 1.2.10

This is a port of the Fitzquake engine to SDL. The main goal of this port is to
allow fitzquake to run on all major platforms. Currently there are builds for
Windows, Linux and Mac OS X.

To run this engine, you need to install the SDL and SDL_net library binaries. For
Linux, you should probably use the packages for your distribution which should be
available through your package manager of choice. The minimum SDL version you
need to run this is 1.2.10. On Windows, you can download the SDL and SDL_net dlls
from http://www.libsdl.org/. On Mac, the SDL framework is included in the
application bundle.

The Mac OS X version includes a simple launcher program.

Known issues:
- Mouse sensitivity is different than in the original Fitzquake (or vanilla Quake,
  for that matter).
- Pasting from the clipboard does not work.
- It is not possible to switch the screen refresh rates from within the engine.
- On Linux, there are problems with the default sound sampling rate of 11025Hz.
  This can be fixed by supplying -sndspeed 48000 on the commandline.

Changes since the March 7 beta:
- discard mouse movement while input is deactivated
- implement maps and mods commands using POSIX functions and added a POSIX wrapper
  for Win32
- activate mouse input when binding a key, otherwise mouse keys cannot be bound
  through the menu
- fixed shift key behaviour
- implemented TCP networking
- fixed fog command (use fmax instead of max in Fog_FogCommand_f)
- fixed bug that lead to the screen being set to minimum size when the sizedown
  command is issued multiple times
- LSHIFT + ESC and circomflex always opens the console
- print everything to stdout
- and more...

ChangeLog:
----------
01/22/2008
- release mouse pointer when console is active.
- enable key repeats (doesn't work on OS X, test in Win32).c

01/23/2008
- implement Sys_SendKeyEvents
- disable mouse input when console is inactive using SDL_SetEventFilter
- move mouse input processing to main event loop
- add vid.mode to determine window mode
- fixed Sys_printf()
- enable key repeats when console is active only
- return 0 if any of the cl_bob vars is 0 in V_CalcBob

01/24/2008
- changed in_deactivate so that it does not always release the mouse cursor
- adapted all calls to in_activate and in_deactive, because they need to be called regardless of the current mode
- added platform dependent messagebox code for fatal errors on OS X and Windows

02/06/2008
- fixed numlock acting as caps lock issue
- fixed: input is not activated on map command (hopefull got them all this time)
- center window in windowed modes

2008/03/14
- discard mouse movement while input is deactivated
- implement maps and mods commands using POSIX functions and added a POSIX wrapper for Win32
- activate mouse input when binding a key, otherwise mouse keys cannot be bound through the menu

2008/06/3
- fixed numerous bugs in sdl_net.c

2008/06/4
- fixed fog command (use fmax instead of max in Fog_FogCommand_f)
- fixed bug that lead to the screen being set to minimum size when the sizedown command is issued multiple times

2008/07/4
- LSHIFT + ESC and circomflex always opens the console

  1.  About

  QuakeSpasm  is a modern, cross-
  platform Quake 1 engine based on FitzQuake
  .

  It includes support for 64 bit CPUs and custom music playback, a new
  sound driver, some graphical niceities, and numerous bug-fixes and
  other improvements.

  Quakespasm utilizes either the SDL or SDL2 frameworks, so choose
  which one works best for you.  SDL is probably less buggy, but SDL2
  has nicer features and smoother mouse input - though no CD support.


  2.  Downloads

  o  Project Downloads: http://quakespasm.sourceforge.net/download.htm

  o  Automatic Builds: http://quakespasm.ericwa.com/job/quakespasm-sdl2/


  3.  Hints

  Visit the FitzQuake homepage  for
  a full run-down of the engine's commands and variables.

  o  To disable some changes, use "quakespasm -fitz"

  o  Quakespasm's custom data is stored in "quakespasm.pak". Install
     this file alongside your id1 directory to enable the custom console
     background and other minor features.

  o  For different sound backend drivers use :
     "SDL_AUDIODRIVER=DRIVER ./quakespasm"
     where DRIVER may be alsa, dsp, pulse, esd ...

  o  Shift+Escape draws the Console.

  o  From the console, use UP to browse the command line history and TAB
     to autocomplete command and map names.

  o  There is currently no CD Music volume support and SDL2 doesn't
     support CD audio. cd_sdl.c needs replacing with cd_linux.c,
     cd_bsd.c etc..

  o  In windows, alternative CD drives are accessible by "quakespasm
     -cddev F" (for example)

  o  Quakespasm allows loading new games (mods) on the fly with "game
     GAMENAME {-quoth/hipnotic/rogue}"

  o  Use "quakespasm -condebug" to save console log to "qconsole.log".
     SDL2 builds no longer generate stdout.txt/stderr.txt.

  3.1.  Music Playback

  Quakespasm can play various external music formats, including MP3, OGG
  and FLAC.

  o  Tracks should be named like "track02.ogg", "track03.ogg" ... (there
     is no track01) and placed into "Quake/id1/music".

  o  Unix users may need some extra libraries installed: "libmad" or
     "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.

  o  As of 0.90.0, music is played back at 44100 Hz by default with no
     need to adjust "-sndspeed".

  o  Use the "-noextmusic" option to disable this feature.

  o  See Quakespasm-Music.txt for more details.

  3.2.  Controller Support

  The SDL2 variant of Quakespasm supports Xbox 360 style game
  controllers.

  The default configuration uses the left analog stick for movement and
  the right for looking.

  If your controller doesn't work you can try placing this file
  https://raw.githubusercontent.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt
  in your Quake directory, it is a community-maintained database that
  adds support for more controllers to SDL2.

  3.2.1.  Cvars

  o  joy_deadzone - Fraction of the stick travel to be deadzone, between
     0 and 1. Default 0.175.

  o  joy_deadzone_trigger - Fraction of trigger range required to
     register a button press on the analog triggers, between 0 and 1.
     Default 0.2.

  o  joy_sensitivity_yaw/pitch - Max angular speed in degrees/second
     when looking. Defaults are 300 for yaw (turning left/right) and 150
     for pitch (up/down).

  o  joy_exponent - For the look stick, the stick displacement (between
     0 and 1) is raised to this power. Default is 3. A value of 1 would
     give a linear relationship between stick displacement and fraction
     of the maximum angular speed.

  o  joy_invert - Set to 1 to invert the vertical axis of the look
     stick.

  o  joy_swapmovelook - Set to 1 to swap the left and right analog stick
     functions. Default 0, move on the left stick, look on the right
     stick.

  o  joy_enable - Set to 0 to disable controller support. Default 1.

  3.2.2.  Buttons

  Some of the controller buttons are hardcoded to allow navigating the
  menu:

  o  Back - alias for TAB

  o  Start - alias for ESC

  o  DPad, analog sticks - mapped to arrow keys

  o  A Button - alias for ENTER in menus

  o  B Button - alias for ESC in menus

  These buttons can be bound normally:

  o  LTRIGGER - Left trigger

  o  RTRIGGER - Right trigger

  o  LSHOULDER - Left shoulder button

  o  RSHOULDER - Right shoulder button

  o  LTHUMB - Clicking the left thumbstick

  o  RTHUMB - Clicking the right thumbstick

  o  ABUTTON

  o  BBUTTON

  o  XBUTTON

  o  YBUTTON

  quakespasm.pak contains a default.cfg which has been updated to give
  some default bindings. L/R shoulder buttons are bound to weapon
  switching, and L/R triggers are jump and attack.

  The controller support started as Jeremiah Sypult's implementation in
  Quakespasm-Rift and also uses ideas and code from LordHavoc
  (DarkPlaces).


  4.  Compiling and Installation

  Quakespasm's (optional) custom data is now stored in the file
  quakespasm.pak. This file should be placed alongside your quakespasm
  binary and id1 directory.

  To checkout the latest version of QuakeSpasm, do:
  svn co svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm

  4.1.  Linux/Unix

  After extracting the source tarball, browse the Makefile and edit the
  music streaming options, then

  ______________________________________________________________________
  make
  cp quakespasm /usr/local/games/quake (for example)
  ______________________________________________________________________


  Compile time options include

  o  make DO_USERDIRS=1 to include user directories support

  o  make DEBUG=1 for debugging

  o  make SDL_CONFIG=/PATH/TO/SDL-CONFIG for unusual SDL installations

  o  make USE_SDL2=1 to compile against SDL2 instead of SDL-1.2

  Streaming music playback requires "libmad" or "libmpg123" for MP3, and
  "libogg" and "libvorbis" for OGG files.

  The project can also be built with Codeblocks (project files
  included).

  4.2.  Windows

  The QuakeSpasm developers cross-compile windows binaries using MinGW
   and Mingw-w64 .

  The project can also be built using Visual Studio 2005 (or newer).

  4.3.  Mac OS X

  A Quakespasm App (including program launcher and update framework) can
  be made using the Xcode template found in the MacOSX directory.

  Alternatively, have a look at Makefile.darwin for more instructions on
  building from a console.


  5.  Known Bugs

  Brightness issues should be fixed with GLSL gamma in 0.90.1, if your
  system supports OpenGL 2. For reference on older systems:

  Some versions of Xorg and SDL have brightness issues.
  Try setting "export SDL_VIDEO_X11_NODIRECTCOLOR=1", or if you have
  Xorg >= 7.5 and broken brightness, these patched libSDL binaries may
  help.

  o  Gamma patched libSDL (i686-linux)
     http://sf.net/projects/quakespasm/files/Support%20Files/libSDL_gamma_patched.tgz/download

  o  Gamma patched libSDL (x86_64-linux)

  o  Change "games" / "mods" commands to list all subdirectories.

  o  Restore vid_refreshrate from fitzquake-0.85 for SDL2 builds.

  o  Alpha-masked model support. (MF_HOLEY: 0x4000).

  o  Invalid skin index now draws skin 0 (WinQuake behaviour) instead of
     blue checkerboard.

  o  Change default screenshot format to png. The 'screenshot' command
     now supports optional format (tga, png or jpg) and quality (1-100)
     arguments.

  o  Revert "always run" changes from 0.85.9 and move the QuakeSpasm
     customizations to a new "cl_alwaysrun" cvar: Set to 1 in order to
     scale forward/side/up speed by "cl_movespeedkey" (usually 2), and
     to make "speedkey" act as "slowkey".

  o  Change "always run" menu option to offer three choices:
   - off        (cl_alwaysrun 0, cl_forwardspeed 200, cl_backspeed 200)
   - vanilla    (cl_alwaysrun 0, cl_forwardspeed 400, cl_backspeed 400)
   - quakespasm (cl_alwaysrun 1, cl_forwardspeed 200, cl_backspeed 200)

  o  New "r_scale" cvar. Set to 2, 3, or 4 to render the view at 1/2,
     1/3, or 1/4 resolution.

  o  New "r_viewmodel_quake" cvar. Set to 1 for WinQuake gun position
     (from MarkV).

  o  New "find" / "apropos" command, searches for commands/cvar names
     for the given substring (from Spike).

  o  New "randmap" command for loading a random map.

  o  New "gl_cshiftpercent_contents", "gl_cshiftpercent_damage",
     "gl_cshiftpercent_bonus", "gl_cshiftpercent_powerup" cvars for
     tuning the strength of specic view blends.

  o  GL2 renderer: use a GLSL shader for world faces. Fixes reports of
     integrated+discrete GPU laptops having inconsistent fog rendering.

  o  Fix macOS startup delay (avoid calling gethostbyname() for ".local"
     hostnames).

  o  Fix memory corruption in PF_lightstyle with out of bounds
     lightstyles.

  o  Fix crash in BoundPoly with polygons extending beyond +/-9999.

  o  Fix QS window to stay on the current monitor when changing video
     modes (SDL2 only).

  o  Fix possible freeze in SV_TouchLinks regardless of what QC does in
     the touch function.

  o  Fix for maps with empty strings for vector keys (e.g. "origin");
     don't read uninitialized memory.

  o  Support for Open Watcom compiler.

  o  Update the third-party libraries.


  6.2.  Changes in 0.92.1

  o  Fixed large menu scale factors (was broken in 0.92.0).

  o  Fixed PAUSE key (was broken in 0.92.0).

  o  Updated some of the third-party libraries.


  6.3.  Changes in 0.92.0

  o  SDL2 Game Controller support.

  o  Contrast support with new "contrast" cvar, behaving the same as
     MarkV. It may be a useful alternative to the existing gamma control
     for laptops in a bright environment, etc. Raising contrast gives
     less of a gray/washed out look than raising gamma, but at a
     disadvantage: colors near white get clipped to white.

  o  RMQ protocol (999) support, adapted from RMQEngine.

  o  New "-protocol x" command line option. Accepted values for 'x' are
     15 (NetQuake), 666 (FitzQuake, default), and 999 (RMQ).

  o  New "setpos" console command.

  o  New "vid_borderless" cvar for getting a borderless window.

  o  Increased MAX_MAP_LEAFS from 65535 to 70000 and MAX_LIGHTMAPS from
     256 to 512 in order to handle the oms3 map pack.

  o  Server edicts are now allocated using malloc instead of allocating
     on the hunk.

  o  gl_clear now defaults to 1.

  o  Fix items falling out of the world on oms3.bsp on SSE builds.

  o  Worked around an OSX 10.6 driver bug when using FSAA, which was
     leading to an unplayable HOM effect on the rest of the screen.

  o  Fix wrong trace endpoint from the tracepos console command.

  o  Updated some of the third-party libraries. Other fixes/clean-ups.


  6.4.  Changes in 0.91.0

  6.4.1.  Bugfixes

  o  Fix unwanted fog mode change upon video restart.

  o  Work around Intel 855 bug in status bar drawing with "r_oldwater 0"
     and "scr_sbaralpha 0".

  o  Fix an obscure GLSL bug where changing gamma would result in the
     screen turning to noise.

  o  Fix GLSL gamma causing the tiled screen border to turn white when
     "sizedown" is used.

  o  Fix an alias model VBO renderer bug where a model not precached
     during map start wouldn't be drawn.

  o  Fix the order of OpenGL context creation and window creation in
     SDL2 video.

  o  Fix a calling convention issue in windows DPI awareness function
     pointers.

  o  Fix a random texture recoloring after video mode change.

  o  Fix a liquid turning to garbage after several video mode changes
     and "r_oldwater 0".

  o  Fix a wrong alpha-sorting bug introduced in 0.90.1.

  o  Fix "flush" command not reloading mdl's from disk (bug introduced
     in 0.90.1).

  o  Prevent a possible buffer overflow in Cbuf_Execute (old Q1/Q2 bug).

  o  Prevent a possible vulnerability in MSG_ReadString (old Q1/Q2 bug).

  6.4.2.  Visual improvements

  o  New cvars r_lavaalpha, r_slimealpha, r_telealpha for fine-tuning
     specific liquid opacities (from DirectQ/RMQEngine, non-archived,
     default to 0), and new worldspawn keys _wateralpha, _lavaalpha,
     _slimealpha, _telealpha, _skyfog (unique to Quakespasm, similar to
     the behaviour of the "fog" worldspawn key).

  o  GLSL gamma is now supported on older hardware without NPOT
     extension.

  6.4.3.  Interface improvements

  o  New r_pos command to show player position.

  o  NaN detection in traceline with "developer 1" set now warns instead
     of errors.

  6.4.4.  Code cleanup / Other

  o  Update third-party libraries.

  6.4.5.  Raised limits

  o  Default max_edicts 8192 (was 2048) and no longer saved to
     config.cfg.

  o  Default heapsize 256 MB (was 64 MB).

  o  Default zone 4 MB (was 384 KB).

  o  Raised MAX_SFX to 1024 (was 512).


  6.5.  Changes in 0.90.1

  6.5.1.  Bugfixes

  o  Fix dynamic light artifact where changing lightmap are rendered one
     frame late (bug introduced in 0.90.0).

  o  Fix texture memory leak when changing video modes with SDL2.

  o  Fix rare incorrect mdl lighting on 64-bit builds. (details here:
     http://forums.insideqc.com/viewtopic.php?f=3&t=5620)

  o  Fix fullbrights turning black after "kill" command (bug introduced
     in 0.90.0).

  o  Clear all fog values on map change to prevent colored fog carrying
     over to jam3_tronyn.bsp.

  o  Allow loading saves with } character in quoted strings, fixes issue
     with retrojam1_skacky.bsp.

  o  Fix viewmodel not lerping on extended-limit maps.

  o  Fix crash on out-of-bounds skin number.

  6.5.2.  Performance

  o  Use multithreaded OpenGL on OS X for better performance.

  o  New, faster mdl renderer using GLSL. Disable with "-noglslalias".

  6.5.3.  Visual improvements

  o  New gamma correction implementation using GLSL. Fixes all known
     gamma issues (affecting the full display, persisting after
     quitting, or darkening the screen on OS X). Disable with
     "-noglslgamma".

  o  Use high-quality water by default (r_oldwater 0).

  o  Shadows use stencil buffer to avoid overlapping artifacts (from
     MarkV.)

  o  r_noshadow_list cvar added (from MarkV.)

  6.5.4.  Interface improvements

  o  Support pausing demo playback with the "pause" command.

  o  Autocompletion for "game", "record", "playdemo".

  o  Experimental windowed fullscreen mode available with
     vid_desktopfullscreen 1 (only in SDL2 builds, takes effect upon
     entering fullscreen mode the next time.)

  o  Silence "exceeded standard limit" messages unless developer cvar is
     >= 1.

  o  Some spam moved from developer 1 to 2: "can't find tga/lit/ent",
     "trying to load ent", "bad chunk length", "meshing",
     "PR_AlocStringSlots: realloc'ing"

  6.5.5.  Code cleanup

  o  Clean up IDE project files to build on fresh systems.

  o  Update 3rd-party libraries.


  6.6.  Changes in 0.90.0

  o  Fix issues on Windows systems with DPI scaling.

  o  Unix/Mac user directories support. Disabled by default,
     'make DO_USERDIRS=1' to enable it.

  o  SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.

  o  Revised keyboard input code.

  o  Revised/improved the 'game' command, i.e. on-the-fly mod changing.
     It now accepts an optional second argument for mission packs or
     quoth support i.e. -hipnotic, -rogue, or -quoth. For example, for
     WarpSpasm: "game warp -quoth"

  o  Command line: "-game {quoth/hipnotic/rogue}" is now treated the
     same as -quoth, -hipnotic, or -rogue.

  o  Console speed now resolution-independent.

  o  Disabled gl_zfix, which caused glitches and is undesirable for new
     maps. Replacement .ent files to fix z-fighting for several id1 maps
     added to quakespasm.pak.

  o  PF_VarString buffer bumped to 1024, avoids truncated centerprints
     from the 'In The Shadows' mod.

  o  Support for opengl non-power-of-two-textures extension (disable
     with command line: "-notexturenpot".)

  o  Support for OpenGL vertex buffer objects (VBO, OpenGL 1.5 or newer)
     for world and brush models (disable with command line: "-novbo".)

  o  Antialiasing (FSAA) support (command line: -fsaa x, where x can be
     0, 2, 4, 8).

  o  Fence textures support.

  o  Dynamic light speedup. Speedup loading of tga and pcx external
     images.

  o  Brush model drawing speedup.

  o  Support for BSP2 and 2PSB map formats.

  o  Support for Opus, FLAC, and tracker music (S3M, IT, UMX, etc.), as
     compile-time options.

  o  Music and sfx now mixed at 44100 Hz to avoid downsampling music.
     Low-pass filter applied to the sfx if -sndspeed is 11025 (the
     default), to preserve the same sound quality as 0.85.9.  New
     -mixspeed option sets the rate for mixing sfx and music, and output
     to the OS (default 44100), setting it to 11025 reverts to 0.85.9
     behaviour. New snd_filterquality cvar, value can be between 1
     (emulate OS X resampler) and 5 (emulate Windows resampler),
     controls the sound of the low-pass filter.

  o  Better Hor+ field of view (FOV) scaling behavior.

  o  Better cross-map demo playback support.

  o  Fix screenshots when screen width isn't a multiple of 4.

  o  Fix a vulnerability in file extension handling. Tighten path
     handling safety.

  o  Initialize opengl with 24-bit depth buffer at 32 bpp.

  o  Reset all models upon gamedir changes. (Fixes failures with mods
     using custom content.)

  o  Fix broken behavior upon gamedir changes if -basedir is specified
     on the command line.

  o  NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.

  o  MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.

  o  MAX_ENT_LEAFS bumped from 16 to 32 to work around disappearing or
     flickering brush models in some situations. Also, if an entity is
     visible from MAX_ENT_LEAFS or more leafs, we now always send it to
     the client.

  o  Fix cvar cycle command not working sometimes.

  o  Host_Error upon missing models. (Prevents segmentation faults.)

  o  Change sv_aim default value to 1 (i.e. turn off autoaim)

  o  Add 'prev' and 'next' keywords to the 'cd' command.

  o  Work around a linux cdrom issue (playback might not start for a
     while after a stop).

  o  Quakespasm content customization moved from engine-embedded into a
     new optional quakespasm.pak file.

  o  Version bumped to 0.90.0 (because Quakespasm has a decent life of
     it's own)

  o  Other fixes and clean-ups.


  6.7.  Changes in 0.85.9

  o  Fixes for several undefined behaviors in C code (gcc-4.8 support.)

  o  Implemented Hor+ style field of view (FOV) scaling, useful for
     widescreen resolutions. Configured by new cvar fov_adapt: set it to
     1 and your fov will be scaled automatically according to the
     resolution. Enabled by default.

  o  Adjusted string buffers for PR_ValueString and friends to fix
     crashes with excessively long global strings seen in some rude
     mods.

  o  Toned down warning messages from PF_VarString() a bit.

  o  Fixed Fitzquake's map existence check in changelevel (used to leak
     file handles which would end up in a Sys_Error() due to consuming
     all free handles if many maps reside not in pak files.)

  o  Fixes/cleanups in chat mode handling. Client no longer gets stuck
     in chat mode upon disconnect.

  o  Mouse grab/key_dest fixes and key cleanups.

  o  The "speedkey" now acts as "slowkey" when "always run" is on.

  o  Support for demo recording after connection to server. (thanks to
     Baker for a patch)

  o  Corner case fixes in COM_Parse() for quoted strings and support for
     C-style /*..*/ comments.

  o  Changed lightmaps to GL_RGBA instead of GL_RGB.

  o  Better parse for opengl extensions list (from quakeforge.)

  o  Vsync saving/loading fixes.

  o  Fixed pointfile loading.

  o  Multiple cleanups in gl_vidsdl.c.

  o  Opus music decoding support (as an optional patch only.)

  o  Several other minor fixes/cleanups.

     Mac OS X.

  o  Better support for building the Mac OS X version using a makefile,
     support for cross-compiling on Linux.

  o  Fixed a minor intermissions glitch.

  o  Increased string buffer size from 256 to 384 for PF_VarString to
     work around broken mods such as UQC.

  o  Restored original behavior for Quake registered version detection.

  o  Minor demo recording/playback tweaks.

  o  Minor tweaks to the scale menu option.

  o  unbindall before loading stored bindings (configurable by new cvar
     cfg_unbindall, enabled by default.)

  o  New icon.

  o  Miscellaneous source code cleanups.

<sect> About <p>

<url url="http://quakespasm.sourceforge.net" name="QuakeSpasm">
is a modern, cross-platform Quake 1 engine based on <url url="http://www.celephais.net/fitzquake" name="FitzQuake">.
</p><p>
It includes support for 64 bit CPUs and custom music playback, a new
sound driver, some graphical niceities, and numerous bug-fixes and other improvements.
</p><p>
Quakespasm utilizes either the SDL or SDL2 frameworks, so choose which one works best for you.
SDL is probably less buggy, but SDL2 has nicer features and smoother mouse input - though no CD support.

</itemize>


<sect> Hints <p>

<em>Visit the <url url="http://www.celephais.net/fitzquake" name="FitzQuake homepage"> for a full run-down of the engine's commands and variables.</em>

<itemize>
<item>To disable some changes, use "<bf>quakespasm -fitz</bf>"

<item>Quakespasm's custom data is stored in "quakespasm.pak". Install this file alongside your id1 directory to enable the custom console background and other minor features.

<item>For different sound backend drivers use "<bf>SDL_AUDIODRIVER=</bf><em>DRIVER</em><bf> ./quakespasm</bf>"
, where DRIVER may be alsa, dsp, pulse, esd ...

<item><bf>Shift+Escape</bf> draws the Console.
<item>From the console, use <bf>UP</bf> to browse the command line history and
<bf>TAB</bf> to autocomplete command and map names.
<item>There is currently no CD Music volume support and SDL2 doesn't support CD audio. cd_sdl.c needs replacing with cd_linux.c, cd_bsd.c etc..
<item>In windows, alternative CD drives are accessible by "<bf>quakespasm -cddev F</bf>" (for example)

<item>Quakespasm allows loading new games (mods) on the fly with "<bf>game</bf> <em>GAMENAME {-quoth/hipnotic/rogue}</em>"

<item>Use "<bf>quakespasm -condebug</bf>" to save console log to "qconsole.log". SDL2 builds no longer generate stdout.txt/stderr.txt.
</itemize>
</p>

<sect1>Music Playback<p>
Quakespasm can play various external music formats, including MP3, OGG and FLAC.
<itemize>
<item>Tracks should be named like "track02.ogg", "track03.ogg" ... (there is no track01) and placed into "Quake/id1/music".
<item>Unix users may need some extra libraries installed: "libmad" or "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.
<item>As of 0.90.0, music is played back at 44100 Hz by default with no need to adjust "-sndspeed".
<item>Use the "-noextmusic" option to disable this feature.
<item>See <url url="Quakespasm-Music.txt"> for more details.
</itemize>

<sect1>Controller Support<p>
The SDL2 variant of Quakespasm supports Xbox 360 style game controllers.
<p>
The default configuration uses the left analog stick for movement and the right for looking.
<p>
If your controller doesn't work you can try placing <url url="https://raw.githubusercontent.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt" name="this file"> in your Quake directory, it is a community-maintained database that adds support for more controllers to SDL2.

<sect2>Cvars<p>
<itemize>
<item>joy_deadzone - Fraction of the stick travel to be deadzone, between 0 and 1. Default 0.175.
<item>joy_deadzone_trigger - Fraction of trigger range required to register a button press on the analog triggers, between 0 and 1. Default 0.2.
<item>joy_sensitivity_yaw/pitch - Max angular speed in degrees/second when looking. Defaults are 300 for yaw (turning left/right) and 150 for pitch (up/down).
<item>joy_exponent - For the look stick, the stick displacement (between 0 and 1) is raised to this power. Default is 3. A value of 1 would give a linear relationship between stick displacement and fraction of the maximum angular speed.
<item>joy_invert - Set to 1 to invert the vertical axis of the look stick.
<item>joy_swapmovelook - Set to 1 to swap the left and right analog stick functions. Default 0, move on the left stick, look on the right stick.
<item>joy_enable - Set to 0 to disable controller support. Default 1.
</itemize>

<sect2>Buttons<p>
Some of the controller buttons are hardcoded to allow navigating the menu:

<itemize>
<item>Back - alias for TAB
<item>Start - alias for ESC
<item>DPad, analog sticks - mapped to arrow keys
<item>A Button - alias for ENTER in menus
<item>B Button - alias for ESC in menus
</itemize>

These buttons can be bound normally:

<itemize>
<item>LTRIGGER - Left trigger
<item>RTRIGGER - Right trigger
<item>LSHOULDER - Left shoulder button
<item>RSHOULDER - Right shoulder button
<item>LTHUMB - Clicking the left thumbstick
<item>RTHUMB - Clicking the right thumbstick
<item>ABUTTON
<item>BBUTTON
<item>XBUTTON
<item>YBUTTON
</itemize>
quakespasm.pak contains a default.cfg which has been updated to give some default bindings. L/R shoulder buttons are bound to weapon switching, and L/R triggers are jump and attack.
<p>
The controller support started as Jeremiah Sypult's implementation in Quakespasm-Rift and also uses ideas and code from LordHavoc (DarkPlaces).

<sect> Compiling and Installation<p>
<p>Quakespasm's (optional) custom data is now stored in the file <bf>quakespasm.pak</bf>. This file should be placed alongside your quakespasm binary and <bf>id1</bf> directory.</p>
<p><em>To checkout the latest version of QuakeSpasm, do:</em>
<bf>svn co svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm</bf></p>

<sect1> Linux/Unix <p>
After extracting the source tarball, browse the Makefile and edit the music streaming options, then
<code>
make
cp quakespasm /usr/local/games/quake (for example)
</code>
<newline>
Compile time options include
<itemize>
<item><bf>make DO_USERDIRS=1</bf> to include user directories support
<item><bf>make DEBUG=1</bf> for debugging
<item><bf>make SDL_CONFIG=</bf><em>/PATH/TO/SDL-CONFIG</em> for unusual SDL installations
<item><bf>make USE_SDL2=1</bf> to compile against SDL2 instead of SDL-1.2
</itemize>
<p>Streaming music playback requires "libmad" or "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG files.
<p>The project can also be built with Codeblocks (project files included).</p>

<sect1> Windows <p>
The QuakeSpasm developers cross-compile windows binaries using <url url="http://www.mingw.org" name="MinGW"> and <url url="http://mingw-w64.sf.net" name="Mingw-w64">.

The project can also be built using Visual Studio 2005 (or newer).</p>

<sect1> Mac OS X <p>
A Quakespasm App (including program launcher and update framework) can be made using the <bf>Xcode</bf> template found in the MacOSX directory.

Alternatively, have a look at <bf>Makefile.darwin</bf> for more instructions on building from a console.
</p>

<sect> Known Bugs <p>
Brightness issues should be fixed with GLSL gamma in 0.90.1, if your system supports OpenGL 2. For reference on older systems:
<newline> 
Some versions of Xorg and SDL have brightness issues.
<newline>
Try setting "export SDL_VIDEO_X11_NODIRECTCOLOR=1", or if you have Xorg >= 7.5 and broken brightness,
these patched libSDL binaries may help.

<item> Alpha-masked model support. (MF_HOLEY: 0x4000).
<item> Invalid skin index now draws skin 0 (WinQuake behaviour) instead of blue checkerboard.
<item> Change default screenshot format to png. The 'screenshot' command now supports optional format (tga, png or jpg) and quality (1-100) arguments.
<item> Revert "always run" changes from 0.85.9 and move the QuakeSpasm customizations to a new "cl_alwaysrun" cvar: Set to 1 in order to scale forward/side/up speed by "cl_movespeedkey" (usually 2), and to make "speedkey" act as "slowkey".
<item> Change the "always run" menu option to offer three choices:
 <itemize>
 <item> off        (cl_alwaysrun 0, cl_forwardspeed 200, cl_backspeed 200)
 <item> vanilla    (cl_alwaysrun 0, cl_forwardspeed 400, cl_backspeed 400)
 <item> quakespasm (cl_alwaysrun 1, cl_forwardspeed 200, cl_backspeed 200)
 </itemize>
<item> New "r_scale" cvar. Set to 2, 3, or 4 to render the view at 1/2, 1/3, or 1/4 resolution.
<item> New "r_viewmodel_quake" cvar. Set to 1 for WinQuake gun position (from MarkV).
<item> New "find" / "apropos" command, searches for commands/cvar names for the given substring (from Spike).
<item> New "randmap" command for loading a random map.
<item> New "gl_cshiftpercent_contents", "gl_cshiftpercent_damage", "gl_cshiftpercent_bonus", "gl_cshiftpercent_powerup" cvars for tuning the strength of specic view blends.
<item> GL2 renderer: use a GLSL shader for world faces. Fixes reports of integrated+discrete GPU laptops having inconsistent fog rendering.
<item> Fix macOS startup delay (avoid calling gethostbyname() for ".local" hostnames).
<item> Fix memory corruption in PF_lightstyle with out of bounds lightstyles.
<item> Fix crash in BoundPoly with polygons extending beyond +/-9999.
<item> Fix QS window to stay on the current monitor when changing video modes (SDL2 only).
<item> Fix possible freeze in SV_TouchLinks regardless of what QC does in the touch function.
<item> Fix for maps with empty strings for vector keys (e.g. "origin"); don't read uninitialized memory.

</itemize>
</p>

<sect1> Changes in 0.92.1<p>
<itemize>

</itemize>
</p>

<sect1> Changes in 0.92.0<p>
<itemize>
<item> SDL2 Game Controller support.
<item> Contrast support with new "contrast" cvar, behaving the same as MarkV. It may be a useful alternative to the existing gamma control for laptops in a bright environment, etc. Raising contrast gives less of a gray/washed out look than raising gamma, but at a disadvantage: colors near white get clipped to white.
<item> RMQ protocol (999) support, adapted from RMQEngine.
<item> New "-protocol x" command line option. Accepted values for 'x' are 15 (NetQuake), 666 (FitzQuake, default), and 999 (RMQ).
<item> New "setpos" console command.
<item> New "vid_borderless" cvar for getting a borderless window.
<item> Increased MAX_MAP_LEAFS from 65535 to 70000 and MAX_LIGHTMAPS from 256 to 512 in order to handle the oms3 map pack.
<item> Server edicts are now allocated using malloc instead of allocating on the hunk.
<item> gl_clear now defaults to 1.
<item> Fix items falling out of the world on oms3.bsp on SSE builds.
<item> Worked around an OSX 10.6 driver bug when using FSAA, which was leading to an unplayable HOM effect on the rest of the screen.
<item> Fix wrong trace endpoint from the tracepos console command.
<item> Updated some of the third-party libraries. Other fixes/clean-ups.
</itemize>
</p>

<sect1> Changes in 0.91.0<p>

<item> Fix a wrong alpha-sorting bug introduced in 0.90.1.
<item> Fix "flush" command not reloading mdl's from disk (bug introduced in 0.90.1).
<item> Prevent a possible buffer overflow in Cbuf_Execute (old Q1/Q2 bug).
<item> Prevent a possible vulnerability in MSG_ReadString (old Q1/Q2 bug).
</itemize>

<sect2> Visual improvements
<itemize>
<item> New cvars r_lavaalpha, r_slimealpha, r_telealpha for fine-tuning specific liquid opacities (from DirectQ/RMQEngine, non-archived, default to 0), and new worldspawn keys _wateralpha, _lavaalpha, _slimealpha, _telealpha, _skyfog (unique to Quakespasm, similar to the behaviour of the "fog" worldspawn key).
<item> GLSL gamma is now supported on older hardware without NPOT extension.
</itemize>

<sect2> Interface improvements
<itemize>
<item> New r_pos command to show player position.
<item> NaN detection in traceline with "developer 1" set now warns instead of errors.
</itemize>

<sect2> Code cleanup / Other
<itemize>
<item> Update third-party libraries.
</itemize>

<sect2> Raised limits
<itemize>
<item> Default max_edicts 8192 (was 2048) and no longer saved to config.cfg.
<item> Default heapsize 256 MB (was 64 MB).
<item> Default zone 4 MB (was 384 KB).

</itemize>

<sect2> Visual improvements
<itemize>
<item> New gamma correction implementation using GLSL. Fixes all known gamma issues (affecting the full display, persisting after quitting, or darkening the screen on OS X). Disable with "-noglslgamma".
<item> Use high-quality water by default (r_oldwater 0).
<item> Shadows use stencil buffer to avoid overlapping artifacts (from MarkV.)
<item> r_noshadow_list cvar added (from MarkV.)
</itemize>

<sect2> Interface improvements
<itemize>
<item> Support pausing demo playback with the "pause" command.
<item> Autocompletion for "game", "record", "playdemo".
<item> Experimental windowed fullscreen mode available with vid_desktopfullscreen 1 (only in SDL2 builds, takes effect upon entering fullscreen mode the next time.)
<item> Silence "exceeded standard limit" messages unless developer cvar is >= 1.
<item> Some spam moved from developer 1 to 2: "can't find tga/lit/ent", "trying to load ent", "bad chunk length", "meshing", "PR_AlocStringSlots: realloc'ing"
</itemize>

<sect2> Code cleanup
<itemize>
<item> Clean up IDE project files to build on fresh systems.
<item> Update 3rd-party libraries.
</itemize>
</p>

<sect1> Changes in 0.90.0<p>
<itemize>
<item> Fix issues on Windows systems with DPI scaling.</item>
<item> Unix/Mac user directories support. Disabled by default, 'make DO_USERDIRS=1' to enable it.
<item> SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.
<item> Revised keyboard input code.
<item> Revised/improved the 'game' command, i.e. on-the-fly mod changing. It now accepts an optional second argument for mission packs or quoth support i.e. -hipnotic, -rogue, or -quoth. For example, for WarpSpasm: "game warp -quoth"
<item> Command line: "-game {quoth/hipnotic/rogue}" is now treated the same as -quoth, -hipnotic, or -rogue.
<item> Console speed now resolution-independent.
<item> Disabled gl_zfix, which caused glitches and is undesirable for new maps. Replacement .ent files to fix z-fighting for several id1 maps added to quakespasm.pak.
<item> PF_VarString buffer bumped to 1024, avoids truncated centerprints from the 'In The Shadows' mod.
<item> Support for opengl non-power-of-two-textures extension (disable with command line: "-notexturenpot".)
<item> Support for OpenGL vertex buffer objects (VBO, OpenGL 1.5 or newer) for world and brush models (disable with command line: "-novbo".)
<item> Antialiasing (FSAA) support (command line: -fsaa x, where x can be 0, 2, 4, 8).
<item> Fence textures support.
<item> Dynamic light speedup. Speedup loading of tga and pcx external images.
<item> Brush model drawing speedup.
<item> Support for BSP2 and 2PSB map formats.
<item> Support for Opus, FLAC, and tracker music (S3M, IT, UMX, etc.), as compile-time options.
<item> Music and sfx now mixed at 44100 Hz to avoid downsampling music. Low-pass filter applied to the sfx if -sndspeed is 11025 (the default), to preserve the same sound quality as 0.85.9.  New -mixspeed option sets the rate for mixing sfx and music, and output to the OS (default 44100), setting it to 11025 reverts to 0.85.9 behaviour. New snd_filterquality cvar, value can be between 1 (emulate OS X resampler) and 5 (emulate Windows resampler), controls the sound of the low-pass filter.
<item> Better Hor+ field of view (FOV) scaling behavior.
<item> Better cross-map demo playback support.
<item> Fix screenshots when screen width isn't a multiple of 4.
<item> Fix a lighting glitch due to floating point precision.
<item> Fix a looping sounds glitch.
<item> Fix a vulnerability in file extension handling. Tighten path handling safety.
<item> Initialize opengl with 24-bit depth buffer at 32 bpp.
<item> Reset all models upon gamedir changes. (Fixes failures with mods using custom content.)
<item> Fix broken behavior upon gamedir changes if -basedir is specified on the command line.
<item> NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.
<item> MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.
<item> MAX_ENT_LEAFS bumped from 16 to 32 to work around disappearing or flickering brush models in some situations. Also, if an entity is visible from MAX_ENT_LEAFS or more leafs, we now always send it to the client.
<item> Fix cvar cycle command not working sometimes.
<item> Host_Error upon missing models. (Prevents segmentation faults.)
<item> Change sv_aim default value to 1 (i.e. turn off autoaim)
<item> Add 'prev' and 'next' keywords to the 'cd' command.
<item> Work around a linux cdrom issue (playback might not start for a while after a stop).
<item> Quakespasm content customization moved from engine-embedded into a new optional quakespasm.pak file.
<item> Version bumped to 0.90.0 (because Quakespasm has a decent life of it's own)
<item> Other fixes and clean-ups.
</itemize>
</p>

<sect1> Changes in 0.85.9<p>
<itemize>
<item> Fixes for several undefined behaviors in C code (gcc-4.8 support.)
<item> Implemented Hor+ style field of view (FOV) scaling, useful for widescreen resolutions. Configured by new cvar fov_adapt: set it to 1 and your fov will be scaled automatically according to the resolution. Enabled by default.
<item> Adjusted string buffers for PR_ValueString and friends to fix crashes with excessively long global strings seen in some rude mods.
<item> Toned down warning messages from PF_VarString() a bit.
<item> Fixed Fitzquake's map existence check in changelevel (used to leak file handles which would end up in a Sys_Error() due to consuming all free handles if many maps reside not in pak files.)
<item> Fixes/cleanups in chat mode handling. Client no longer gets stuck in chat mode upon disconnect.
<item> Mouse grab/key_dest fixes and key cleanups.

                       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.

                    GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

  5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

  7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

  10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

                            NO WARRANTY

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

    Gnomovision version 69, Copyright (C) year name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  `Gnomovision' (which makes passes at compilers) written by James Hacker.

  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.
����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������quakespasm-0.93.0/Quakespasm-Music.txt��������������������������������������������������������������0000644�0000000�0000000�00000006346�12405526374�016425� 0����������������������������������������������������������������������������������������������������ustar  �root����������������������������root�������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������QuakeSpasm supports ogg, mp3 and wav external music files to be played
instead of cd music. What you should do is simple:

1. Use your favorite cd-ripper application and rip your quake cdrom
   audio tracks, convert them to ogg or mp3 so they occupy less space,
   like track02.ogg, track03.ogg, etc.

   Note #1: There is no such thing as track01:  the first tracks of
            original Quake and the mission pack cdroms are always data
            tracks.

   Note #2: Since the Quake cdrom audio tracks are pre-emphasized, you
            should de-emphasize them during or after ripping to make
            them sound right. (thanks to Sander van Dijk for this note)

2. Go into your quake installation directory and create a new directory
   id1/music (for windows users id1\music).

3. If you have the Scourge of Armagon mission pack, then create another
   directory hipnotic/music .  If you have the Dissolution of Eternity
   then create another directory rogue/music .

4. Take the ripped music files from step1, place them under id1/music.
   If you have the mission packs, repeat step1 for the mission packs,
   too, and place the ripped music files under hipnotic/music for the
   first mission pack or under rogue/music for the second mission pack.

5. All are ready to go: When a level starts, the engine will first try
   playing the necessary cdaudio track and if it doesn't find the cdrom
   it will use the ripped music files instead.


New console commands:
---------------------
- music <filename>
  Start playing the requested music file.
  Example:  music mymusic1

  Notice that you don't have to type the file extension: The requested
  music will be searched with ogg, mp3, and then with a wav extension,
  automatically.

  If you do specify the file extension, like "music mymusic1.wav", then
  it will honor your wish and try only the given type: this is good for
  testing/comparing the same music in different formats.

- music_stop
  Stops the playing music

- music_pause
  Pauses the playing music

- music_resume
  Resumes playing the music if it was paused

- music_loop 1
  Makes the background music to loop (default behavior)

- music_loop 0
  Makes the background music to play once and then stop

New cvars:
-------------------------
- bgm_extmusic (0 or 1): Disable or enable playback of external music
  files instead of cdaudio. default is 1 (enabled).

New command line options:
-------------------------
- -noextmusic: Disables the playback of external music files instead of
  cdaudio.

Music files in PAK files:
-------------------------
PAK-contained music files are fully supported.

Music file directories:
-------------------------
- The music files are always searched under the "music" subdirectory of
  a game.

Music file search order:
-------------------------
The engine can handle multiple audio formats.  The map-dictated music,
i.e. the ripped cd music, is always searched by the order of searchpath
priority:  the file from the searchpath with the highest priority is
chosen, because it is most likely the one from our own game directory
itself.  This way, if a mod has track02 as a mp3 or wav, which is below
track02.ogg in the music_handler order, the mp3 or wav will still have
priority over track02.ogg from the id1 game directory.

/*

All of Quake's data access is through a hierchal file system, but the contents
of the file system can be transparently merged from several sources.

The "base directory" is the path to the directory holding the quake.exe and all
game directories.  The sys_* files pass this to host_init in quakeparms_t->basedir.
This can be overridden with the "-basedir" command line parm to allow code
debugging in a different directory.  The base directory is only used during
filesystem initialization.

The "game directory" is the first tree on the search path and directory that all
generated files (savegames, screenshots, demos, config files) will be saved to.
This can be overridden with the "-game" command line parameter.  The game
directory can never be changed while quake is executing.  This is a precacution
against having a malicious server instruct clients to write files over areas they
shouldn't.

The "cache directory" is only used during development to save network bandwidth,
especially over ISDN / T1 lines.  If there is a cache directory specified, when
a file is found by the normal search path, it will be mirrored into the cache
directory, then opened there.

FIXME:
The file "parms.txt" will be read out of the game directory and appended to the
current command line arguments to allow different games to initialize startup
parms differently.  This could be used to add a "-sspeed 22050" for the high
quality sound edition.  Because they are added at the end, they will not
override an explicit setting on the original command line.

/*
 memory allocation


H_??? The hunk manages the entire memory block given to quake.  It must be
contiguous.  Memory can be allocated from either the low or high end in a
stack fashion.  The only way memory is released is by resetting one of the
pointers.

Hunk allocations should be given a name, so the Hunk_Print () function
can display usage.

Hunk allocations are guaranteed to be 16 byte aligned.

The video buffers are allocated high to avoid leaving a hole underneath
server allocations when changing to a higher video mode.


Z_??? Zone memory functions used for small, dynamic allocations like text
strings from command input.  There is only about 48K for it, allocated at
the very bottom of the hunk.

Cache_??? Cache memory is for objects that can be dynamically loaded and
can usefully stay persistant between levels.  The size of the cache
fluctuates from level to level.

To allocate a cachable object


Temp_??? Temp memory is used for file loading and surface caching.  The size
of the cache memory is adjusted so that there is a minimum of 512k remaining
for temp memory.


------ Top of Memory -------

high hunk allocations

<--- high hunk reset point held by vid

video buffer

z buffer

surface cache

<--- high hunk used

cachable memory

<--- low hunk used

client and server low hunk allocations

<-- low hunk reset point held by host

#ifndef __CVAR_H__
#define __CVAR_H__

/*
cvar_t variables are used to hold scalar or string variables that can
be changed or displayed at the console or prog code as well as accessed
directly in C code.

it is sufficient to initialize a cvar_t with just the first two fields,
or you can add a ,true flag for variables that you want saved to the
configuration file when the game is quit:

cvar_t	r_draworder = {"r_draworder","1"};
cvar_t	scr_screensize = {"screensize","1",true};

Cvars must be registered before use, or they will have a 0 value instead
of the float interpretation of the string.
Generally, all cvar_t declarations should be registered in the apropriate
init function before any console commands are executed:

Cvar_RegisterVariable (&host_framerate);


C code usually just references a cvar in place:
if ( r_draworder.value )

It could optionally ask for the value to be looked up for a string name:
if (Cvar_VariableValue ("r_draworder"))

Interpreted prog code can access cvars with the cvar(name) or
cvar_set (name, value) internal functions:
teamplay = cvar("teamplay");
cvar_set ("registered", "1");

The user can access cvars from the console in two ways:
r_draworder		prints the current value
r_draworder 0		sets the current value to 0

Cvars are restricted from having the same names as commands to keep this
interface from being ambiguous.

About uivector, ucvector and string:
-All of them wrap dynamic arrays or text strings in a similar way.
-LodePNG was originally written in C++. The vectors replace the std::vectors that were used in the C++ version.
-The string tools are made to avoid problems with compilers that declare things like strncat as deprecated.
-They're not used in the interface, only internally in this file as static functions.
-As with many other structs in this file, the init and cleanup functions serve as ctor and dtor.

/* stb_image_write - v1.07 - public domain - http://nothings.org/stb/stb_image_write.h
   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
                                     no warranty implied; use at your own risk

   Before #including,

       #define STB_IMAGE_WRITE_IMPLEMENTATION

   in the file that you want to have the implementation.

   Will probably not work correctly with strict-aliasing optimizations.

ABOUT:

   This header file is a library for writing images to C stdio. It could be
   adapted to write to memory or a general streaming interface; let me know.

   The PNG output is not optimal; it is 20-50% larger than the file
   written by a decent optimizing implementation. This library is designed
   for source code compactness and simplicity, not optimal image file size
   or run-time performance.

BUILDING:

   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
   malloc,realloc,free.
   You can define STBIW_MEMMOVE() to replace memmove()

USAGE:

   There are four functions, one for each image file format:

     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
     int stbi_write_jpg(char const *filename, int w, int h, int comp, const float *data);

   There are also four equivalent functions that use an arbitrary write function. You are
   expected to open/close your file-equivalent before and after calling these:

     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);

   where the callback is:
      void stbi_write_func(void *context, void *data, int size);

   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
   functions, so the library will not use stdio.h at all. However, this will
   also disable HDR writing, because it requires stdio for formatted output.

   Each function returns 0 on failure and non-0 on success.

   The functions create an image file defined by the parameters. The image
   is a rectangle of pixels stored from left-to-right, top-to-bottom.
   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
   The *data pointer points to the first byte of the top-left-most pixel.
   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
   a row of pixels to the first byte of the next row of pixels.

   PNG creates output files with the same number of components as the input.
   The BMP format expands Y to RGB in the file format and does not
   output alpha.

   PNG supports writing rectangles of data even when the bytes storing rows of
   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
   by supplying the stride between the beginning of adjacent rows. The other
   formats do not. (Thus you cannot write a native-format BMP through the BMP
   writer, both because it is in BGR order and because it may have padding
   at the end of the line.)

   HDR expects linear float data. Since the format is always 32-bit rgb(e)
   data, alpha (if provided) is discarded, and for monochrome data it is
   replicated across all three channels.

   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
   data, set the global variable 'stbi_write_tga_with_rle' to 0.
   
   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
   Higher quality looks better but results in a bigger image.
   JPEG baseline (no JPEG progressive).

1. about
--------

PNG is a file format to store raster images losslessly with good compression,
supporting different color types and alpha channel.

LodePNG is a PNG codec according to the Portable Network Graphics (PNG)
Specification (Second Edition) - W3C Recommendation 10 November 2003.

The specifications used are:

*) Portable Network Graphics (PNG) Specification (Second Edition):
     http://www.w3.org/TR/2003/REC-PNG-20031110
*) RFC 1950 ZLIB Compressed Data Format version 3.3:
     http://www.gzip.org/zlib/rfc-zlib.html
*) RFC 1951 DEFLATE Compressed Data Format Specification ver 1.3:
     http://www.gzip.org/zlib/rfc-deflate.html

The most recent version of LodePNG can currently be found at
http://lodev.org/lodepng/

LodePNG works both in C (ISO C90) and C++, with a C++ wrapper that adds
extra functionality.

LodePNG exists out of two files:
-lodepng.h: the header file for both C and C++
-lodepng.c(pp): give it the name lodepng.c or lodepng.cpp (or .cc) depending on your usage

If you want to start using LodePNG right away without reading this doc, get the
examples from the LodePNG website to see how to use it in code, or check the
smaller examples in chapter 13 here.

LodePNG is simple but only supports the basic requirements. To achieve
simplicity, the following design choices were made: There are no dependencies
on any external library. There are functions to decode and encode a PNG with
a single function call, and extended versions of these functions taking a
LodePNGState struct allowing to specify or get more information. By default
the colors of the raw image are always RGB or RGBA, no matter what color type
the PNG file uses. To read and write files, there are simple functions to
convert the files to/from buffers in memory.

This all makes LodePNG suitable for loading textures in games, demos and small
programs, ... It's less suitable for full fledged image editors, loading PNGs
over network (it requires all the image data to be available before decoding can
begin), life-critical systems, ...

1.1. supported features
-----------------------

The following features are supported by the decoder:

*) decoding of PNGs with any color type, bit depth and interlace mode, to a 24- or 32-bit color raw image,
   or the same color type as the PNG
*) encoding of PNGs, from any raw image to 24- or 32-bit color, or the same color type as the raw image
*) Adam7 interlace and deinterlace for any color type
*) loading the image from harddisk or decoding it from a buffer from other sources than harddisk
*) support for alpha channels, including RGBA color model, translucent palettes and color keying
*) zlib decompression (inflate)
*) zlib compression (deflate)
*) CRC32 and ADLER32 checksums
*) handling of unknown chunks, allowing making a PNG editor that stores custom and unknown chunks.
*) the following chunks are supported (generated/interpreted) by both encoder and decoder:
    IHDR: header information
    PLTE: color palette
    IDAT: pixel data
    IEND: the final chunk
    tRNS: transparency for palettized images
    tEXt: textual information
    zTXt: compressed textual information
    iTXt: international textual information
    bKGD: suggested background color
    pHYs: physical dimensions
    tIME: modification time

1.2. features not supported
---------------------------

The following features are _not_ supported:

*) some features needed to make a conformant PNG-Editor might be still missing.
*) partial loading/stream processing. All data must be available and is processed in one call.
*) The following public chunks are not supported but treated as unknown chunks by LodePNG
    cHRM, gAMA, iCCP, sRGB, sBIT, hIST, sPLT
   Some of these are not supported on purpose: LodePNG wants to provide the RGB values
   stored in the pixels, not values modified by system dependent gamma or color models.


2. C and C++ version
--------------------

The C version uses buffers allocated with alloc that you need to free()
yourself. You need to use init and cleanup functions for each struct whenever
using a struct from the C version to avoid exploits and memory leaks.

The C++ version has extra functions with std::vectors in the interface and the
lodepng::State class which is a LodePNGState with constructor and destructor.

These files work without modification for both C and C++ compilers because all
the additional C++ code is in "#ifdef __cplusplus" blocks that make C-compilers
ignore it, and the C code is made to compile both with strict ISO C90 and C++.

To use the C++ version, you need to rename the source file to lodepng.cpp
(instead of lodepng.c), and compile it with a C++ compiler.

To use the C version, you need to rename the source file to lodepng.c (instead
of lodepng.cpp), and compile it with a C compiler.


3. Security
-----------

Even if carefully designed, it's always possible that LodePNG contains possible
exploits. If you discover one, please let me know, and it will be fixed.

When using LodePNG, care has to be taken with the C version of LodePNG, as well
as the C-style structs when working with C++. The following conventions are used
for all C-style structs:

-if a struct has a corresponding init function, always call the init function when making a new one
-if a struct has a corresponding cleanup function, call it before the struct disappears to avoid memory leaks
-if a struct has a corresponding copy function, use the copy function instead of "=".
 The destination must also be inited already.


4. Decoding
-----------

Decoding converts a PNG compressed image to a raw pixel buffer.

Most documentation on using the decoder is at its declarations in the header
above. For C, simple decoding can be done with functions such as
lodepng_decode32, and more advanced decoding can be done with the struct
LodePNGState and lodepng_decode. For C++, all decoding can be done with the
various lodepng::decode functions, and lodepng::State can be used for advanced
features.

When using the LodePNGState, it uses the following fields for decoding:
*) LodePNGInfo info_png: it stores extra information about the PNG (the input) in here
*) LodePNGColorMode info_raw: here you can say what color mode of the raw image (the output) you want to get
*) LodePNGDecoderSettings decoder: you can specify a few extra settings for the decoder to use

LodePNGInfo info_png
--------------------

After decoding, this contains extra information of the PNG image, except the actual
pixels, width and height because these are already gotten directly from the decoder
functions.

It contains for example the original color type of the PNG image, text comments,
suggested background color, etc... More details about the LodePNGInfo struct are
at its declaration documentation.

LodePNGColorMode info_raw
-------------------------

When decoding, here you can specify which color type you want
the resulting raw image to be. If this is different from the colortype of the
PNG, then the decoder will automatically convert the result. This conversion
always works, except if you want it to convert a color PNG to greyscale or to
a palette with missing colors.

By default, 32-bit color is used for the result.

LodePNGDecoderSettings decoder
------------------------------

The settings can be used to ignore the errors created by invalid CRC and Adler32
chunks, and to disable the decoding of tEXt chunks.

There's also a setting color_convert, true by default. If false, no conversion
is done, the resulting data will be as it was in the PNG (after decompression)
and you'll have to puzzle the colors of the pixels together yourself using the
color type information in the LodePNGInfo.


5. Encoding
-----------

Encoding converts a raw pixel buffer to a PNG compressed image.

Most documentation on using the encoder is at its declarations in the header
above. For C, simple encoding can be done with functions such as
lodepng_encode32, and more advanced decoding can be done with the struct
LodePNGState and lodepng_encode. For C++, all encoding can be done with the
various lodepng::encode functions, and lodepng::State can be used for advanced
features.

Like the decoder, the encoder can also give errors. However it gives less errors
since the encoder input is trusted, the decoder input (a PNG image that could
be forged by anyone) is not trusted.

When using the LodePNGState, it uses the following fields for encoding:
*) LodePNGInfo info_png: here you specify how you want the PNG (the output) to be.
*) LodePNGColorMode info_raw: here you say what color type of the raw image (the input) has
*) LodePNGEncoderSettings encoder: you can specify a few settings for the encoder to use

LodePNGInfo info_png
--------------------

When encoding, you use this the opposite way as when decoding: for encoding,
you fill in the values you want the PNG to have before encoding. By default it's
not needed to specify a color type for the PNG since it's automatically chosen,
but it's possible to choose it yourself given the right settings.

The encoder will not always exactly match the LodePNGInfo struct you give,
it tries as close as possible. Some things are ignored by the encoder. The
encoder uses, for example, the following settings from it when applicable:
colortype and bitdepth, text chunks, time chunk, the color key, the palette, the
background color, the interlace method, unknown chunks, ...

When encoding to a PNG with colortype 3, the encoder will generate a PLTE chunk.
If the palette contains any colors for which the alpha channel is not 255 (so
there are translucent colors in the palette), it'll add a tRNS chunk.

LodePNGColorMode info_raw
-------------------------

You specify the color type of the raw image that you give to the input here,
including a possible transparent color key and palette you happen to be using in
your raw image data.

By default, 32-bit color is assumed, meaning your input has to be in RGBA
format with 4 bytes (unsigned chars) per pixel.

LodePNGEncoderSettings encoder
------------------------------

The following settings are supported (some are in sub-structs):
*) auto_convert: when this option is enabled, the encoder will
automatically choose the smallest possible color mode (including color key) that
can encode the colors of all pixels without information loss.
*) btype: the block type for LZ77. 0 = uncompressed, 1 = fixed huffman tree,
   2 = dynamic huffman tree (best compression). Should be 2 for proper
   compression.
*) use_lz77: whether or not to use LZ77 for compressed block types. Should be
   true for proper compression.
*) windowsize: the window size used by the LZ77 encoder (1 - 32768). Has value
   2048 by default, but can be set to 32768 for better, but slow, compression.
*) force_palette: if colortype is 2 or 6, you can make the encoder write a PLTE
   chunk if force_palette is true. This can used as suggested palette to convert
   to by viewers that don't support more than 256 colors (if those still exist)
*) add_id: add text chunk "Encoder: LodePNG <version>" to the image.
*) text_compression: default 1. If 1, it'll store texts as zTXt instead of tEXt chunks.
  zTXt chunks use zlib compression on the text. This gives a smaller result on
  large texts but a larger result on small texts (such as a single program name).
  It's all tEXt or all zTXt though, there's no separate setting per text yet.


6. color conversions
--------------------

An important thing to note about LodePNG, is that the color type of the PNG, and
the color type of the raw image, are completely independent. By default, when
you decode a PNG, you get the result as a raw image in the color type you want,
no matter whether the PNG was encoded with a palette, greyscale or RGBA color.
And if you encode an image, by default LodePNG will automatically choose the PNG
color type that gives good compression based on the values of colors and amount
of colors in the image. It can be configured to let you control it instead as
well, though.

To be able to do this, LodePNG does conversions from one color mode to another.
It can convert from almost any color type to any other color type, except the
following conversions: RGB to greyscale is not supported, and converting to a
palette when the palette doesn't have a required color is not supported. This is
not supported on purpose: this is information loss which requires a color
reduction algorithm that is beyong the scope of a PNG encoder (yes, RGB to grey
is easy, but there are multiple ways if you want to give some channels more
weight).

By default, when decoding, you get the raw image in 32-bit RGBA or 24-bit RGB
color, no matter what color type the PNG has. And by default when encoding,
LodePNG automatically picks the best color model for the output PNG, and expects
the input image to be 32-bit RGBA or 24-bit RGB. So, unless you want to control
the color format of the images yourself, you can skip this chapter.

6.1. PNG color types
--------------------

A PNG image can have many color types, ranging from 1-bit color to 64-bit color,
as well as palettized color modes. After the zlib decompression and unfiltering
in the PNG image is done, the raw pixel data will have that color type and thus
a certain amount of bits per pixel. If you want the output raw image after
decoding to have another color type, a conversion is done by LodePNG.

The PNG specification gives the following color types:

0: greyscale, bit depths 1, 2, 4, 8, 16
2: RGB, bit depths 8 and 16
3: palette, bit depths 1, 2, 4 and 8
4: greyscale with alpha, bit depths 8 and 16
6: RGBA, bit depths 8 and 16

Bit depth is the amount of bits per pixel per color channel. So the total amount
of bits per pixel is: amount of channels * bitdepth.

6.2. color conversions
----------------------

As explained in the sections about the encoder and decoder, you can specify
color types and bit depths in info_png and info_raw to change the default
behaviour.

If, when decoding, you want the raw image to be something else than the default,
you need to set the color type and bit depth you want in the LodePNGColorMode,
or the parameters colortype and bitdepth of the simple decoding function.

If, when encoding, you use another color type than the default in the raw input
image, you need to specify its color type and bit depth in the LodePNGColorMode
of the raw image, or use the parameters colortype and bitdepth of the simple
encoding function.

If, when encoding, you don't want LodePNG to choose the output PNG color type
but control it yourself, you need to set auto_convert in the encoder settings
to false, and specify the color type you want in the LodePNGInfo of the
encoder (including palette: it can generate a palette if auto_convert is true,
otherwise not).

If the input and output color type differ (whether user chosen or auto chosen),
LodePNG will do a color conversion, which follows the rules below, and may
sometimes result in an error.

To avoid some confusion:
-the decoder converts from PNG to raw image
-the encoder converts from raw image to PNG
-the colortype and bitdepth in LodePNGColorMode info_raw, are those of the raw image
-the colortype and bitdepth in the color field of LodePNGInfo info_png, are those of the PNG
-when encoding, the color type in LodePNGInfo is ignored if auto_convert
 is enabled, it is automatically generated instead
-when decoding, the color type in LodePNGInfo is set by the decoder to that of the original
 PNG image, but it can be ignored since the raw image has the color type you requested instead
-if the color type of the LodePNGColorMode and PNG image aren't the same, a conversion
 between the color types is done if the color types are supported. If it is not
 supported, an error is returned. If the types are the same, no conversion is done.
-even though some conversions aren't supported, LodePNG supports loading PNGs from any
 colortype and saving PNGs to any colortype, sometimes it just requires preparing
 the raw image correctly before encoding.
-both encoder and decoder use the same color converter.

Non supported color conversions:
-color to greyscale: no error is thrown, but the result will look ugly because
only the red channel is taken
-anything to palette when that palette does not have that color in it: in this
case an error is thrown

Supported color conversions:
-anything to 8-bit RGB, 8-bit RGBA, 16-bit RGB, 16-bit RGBA
-any grey or grey+alpha, to grey or grey+alpha
-anything to a palette, as long as the palette has the requested colors in it
-removing alpha channel
-higher to smaller bitdepth, and vice versa

If you want no color conversion to be done (e.g. for speed or control):
-In the encoder, you can make it save a PNG with any color type by giving the
raw color mode and LodePNGInfo the same color mode, and setting auto_convert to
false.
-In the decoder, you can make it store the pixel data in the same color type
as the PNG has, by setting the color_convert setting to false. Settings in
info_raw are then ignored.

The function lodepng_convert does the color conversion. It is available in the
interface but normally isn't needed since the encoder and decoder already call
it.

6.3. padding bits
-----------------

In the PNG file format, if a less than 8-bit per pixel color type is used and the scanlines
have a bit amount that isn't a multiple of 8, then padding bits are used so that each
scanline starts at a fresh byte. But that is NOT true for the LodePNG raw input and output.
The raw input image you give to the encoder, and the raw output image you get from the decoder
will NOT have these padding bits, e.g. in the case of a 1-bit image with a width
of 7 pixels, the first pixel of the second scanline will the the 8th bit of the first byte,
not the first bit of a new byte.

6.4. A note about 16-bits per channel and endianness
----------------------------------------------------

LodePNG uses unsigned char arrays for 16-bit per channel colors too, just like
for any other color format. The 16-bit values are stored in big endian (most
significant byte first) in these arrays. This is the opposite order of the
little endian used by x86 CPU's.

LodePNG always uses big endian because the PNG file format does so internally.
Conversions to other formats than PNG uses internally are not supported by
LodePNG on purpose, there are myriads of formats, including endianness of 16-bit
colors, the order in which you store R, G, B and A, and so on. Supporting and
converting to/from all that is outside the scope of LodePNG.

This may mean that, depending on your use case, you may want to convert the big
endian output of LodePNG to little endian with a for loop. This is certainly not
always needed, many applications and libraries support big endian 16-bit colors
anyway, but it means you cannot simply cast the unsigned char* buffer to an
unsigned short* buffer on x86 CPUs.


7. error values
---------------

All functions in LodePNG that return an error code, return 0 if everything went
OK, or a non-zero code if there was an error.

The meaning of the LodePNG error values can be retrieved with the function
lodepng_error_text: given the numerical error code, it returns a description
of the error in English as a string.

8. chunks and PNG editing
-------------------------

If you want to add extra chunks to a PNG you encode, or use LodePNG for a PNG
editor that should follow the rules about handling of unknown chunks, or if your
program is able to read other types of chunks than the ones handled by LodePNG,
then that's possible with the chunk functions of LodePNG.

A PNG chunk has the following layout:

4 bytes length
4 bytes type name
length bytes data
4 bytes CRC

8.1. iterating through chunks
-----------------------------

If you have a buffer containing the PNG image data, then the first chunk (the
IHDR chunk) starts at byte number 8 of that buffer. The first 8 bytes are the
signature of the PNG and are not part of a chunk. But if you start at byte 8
then you have a chunk, and can check the following things of it.

NOTE: none of these functions check for memory buffer boundaries. To avoid
exploits, always make sure the buffer contains all the data of the chunks.
When using lodepng_chunk_next, make sure the returned value is within the
allocated memory.

unsigned lodepng_chunk_length(const unsigned char* chunk):

Get the length of the chunk's data. The total chunk length is this length + 12.

void lodepng_chunk_type(char type[5], const unsigned char* chunk):
unsigned char lodepng_chunk_type_equals(const unsigned char* chunk, const char* type):

Get the type of the chunk or compare if it's a certain type

unsigned char lodepng_chunk_critical(const unsigned char* chunk):
unsigned char lodepng_chunk_private(const unsigned char* chunk):
unsigned char lodepng_chunk_safetocopy(const unsigned char* chunk):

Check if the chunk is critical in the PNG standard (only IHDR, PLTE, IDAT and IEND are).
Check if the chunk is private (public chunks are part of the standard, private ones not).
Check if the chunk is safe to copy. If it's not, then, when modifying data in a critical
chunk, unsafe to copy chunks of the old image may NOT be saved in the new one if your
program doesn't handle that type of unknown chunk.

unsigned char* lodepng_chunk_data(unsigned char* chunk):
const unsigned char* lodepng_chunk_data_const(const unsigned char* chunk):

Get a pointer to the start of the data of the chunk.

unsigned lodepng_chunk_check_crc(const unsigned char* chunk):
void lodepng_chunk_generate_crc(unsigned char* chunk):

Check if the crc is correct or generate a correct one.

unsigned char* lodepng_chunk_next(unsigned char* chunk):
const unsigned char* lodepng_chunk_next_const(const unsigned char* chunk):

Iterate to the next chunk. This works if you have a buffer with consecutive chunks. Note that these
functions do no boundary checking of the allocated data whatsoever, so make sure there is enough
data available in the buffer to be able to go to the next chunk.

unsigned lodepng_chunk_append(unsigned char** out, size_t* outlength, const unsigned char* chunk):
unsigned lodepng_chunk_create(unsigned char** out, size_t* outlength, unsigned length,
                              const char* type, const unsigned char* data):

These functions are used to create new chunks that are appended to the data in *out that has
length *outlength. The append function appends an existing chunk to the new data. The create
function creates a new chunk with the given parameters and appends it. Type is the 4-letter
name of the chunk.

8.2. chunks in info_png
-----------------------

The LodePNGInfo struct contains fields with the unknown chunk in it. It has 3
buffers (each with size) to contain 3 types of unknown chunks:
the ones that come before the PLTE chunk, the ones that come between the PLTE
and the IDAT chunks, and the ones that come after the IDAT chunks.
It's necessary to make the distionction between these 3 cases because the PNG
standard forces to keep the ordering of unknown chunks compared to the critical
chunks, but does not force any other ordering rules.

info_png.unknown_chunks_data[0] is the chunks before PLTE
info_png.unknown_chunks_data[1] is the chunks after PLTE, before IDAT
info_png.unknown_chunks_data[2] is the chunks after IDAT

The chunks in these 3 buffers can be iterated through and read by using the same
way described in the previous subchapter.

When using the decoder to decode a PNG, you can make it store all unknown chunks
if you set the option settings.remember_unknown_chunks to 1. By default, this
option is off (0).

The encoder will always encode unknown chunks that are stored in the info_png.
If you need it to add a particular chunk that isn't known by LodePNG, you can
use lodepng_chunk_append or lodepng_chunk_create to the chunk data in
info_png.unknown_chunks_data[x].

Chunks that are known by LodePNG should not be added in that way. E.g. to make
LodePNG add a bKGD chunk, set background_defined to true and add the correct
parameters there instead.


9. compiler support
-------------------

No libraries other than the current standard C library are needed to compile
LodePNG. For the C++ version, only the standard C++ library is needed on top.
Add the files lodepng.c(pp) and lodepng.h to your project, include
lodepng.h where needed, and your program can read/write PNG files.

It is compatible with C90 and up, and C++03 and up.

If performance is important, use optimization when compiling! For both the
encoder and decoder, this makes a large difference.

Make sure that LodePNG is compiled with the same compiler of the same version
and with the same settings as the rest of the program, or the interfaces with
std::vectors and std::strings in C++ can be incompatible.

CHAR_BITS must be 8 or higher, because LodePNG uses unsigned chars for octets.

*) gcc and g++

LodePNG is developed in gcc so this compiler is natively supported. It gives no
warnings with compiler options "-Wall -Wextra -pedantic -ansi", with gcc and g++
version 4.7.1 on Linux, 32-bit and 64-bit.

*) Clang

Fully supported and warning-free.

*) Mingw

The Mingw compiler (a port of gcc for Windows) should be fully supported by
LodePNG.

*) Visual Studio and Visual C++ Express Edition

LodePNG should be warning-free with warning level W4. Two warnings were disabled
with pragmas though: warning 4244 about implicit conversions, and warning 4996
where it wants to use a non-standard function fopen_s instead of the standard C
fopen.

Visual Studio may want "stdafx.h" files to be included in each source file and
give an error "unexpected end of file while looking for precompiled header".
This is not standard C++ and will not be added to the stock LodePNG. You can
disable it for lodepng.cpp only by right clicking it, Properties, C/C++,
Precompiled Headers, and set it to Not Using Precompiled Headers there.

NOTE: Modern versions of VS should be fully supported, but old versions, e.g.
VS6, are not guaranteed to work.

*) Compilers on Macintosh

LodePNG has been reported to work both with gcc and LLVM for Macintosh, both for
C and C++.

*) Other Compilers

If you encounter problems on any compilers, feel free to let me know and I may
try to fix it if the compiler is modern and standards complient.


10. examples
------------

This decoder example shows the most basic usage of LodePNG. More complex
examples can be found on the LodePNG website.

10.1. decoder C++ example
-------------------------

#include "lodepng.h"
#include <iostream>

int main(int argc, char *argv[])
{
  const char* filename = argc > 1 ? argv[1] : "test.png";

  //load and decode
  std::vector<unsigned char> image;
  unsigned width, height;
  unsigned error = lodepng::decode(image, width, height, filename);

  //if there's an error, display it
  if(error) std::cout << "decoder error " << error << ": " << lodepng_error_text(error) << std::endl;

  //the pixels are now in the vector "image", 4 bytes per pixel, ordered RGBARGBA..., use it as texture, draw it, ...
}

10.2. decoder C example
-----------------------

#include "lodepng.h"

int main(int argc, char *argv[])
{
  unsigned error;
  unsigned char* image;
  size_t width, height;
  const char* filename = argc > 1 ? argv[1] : "test.png";

  error = lodepng_decode32_file(&image, &width, &height, filename);

  if(error) printf("decoder error %u: %s\n", error, lodepng_error_text(error));

  / * use image here * /

  free(image);
  return 0;
}

   the limits of pure C90).
*) 08 dec 2015: Made load_file function return error if file can't be opened.
*) 24 okt 2015: Bugfix with decoding to palette output.
*) 18 apr 2015: Boundary PM instead of just package-merge for faster encoding.
*) 23 aug 2014: Reduced needless memory usage of decoder.

*) 22 dec 2013: Power of two windowsize required for optimization.
*) 15 apr 2013: Fixed bug with LAC_ALPHA and color key.
*) 25 mar 2013: Added an optional feature to ignore some PNG errors (fix_png).
*) 11 mar 2013 (!): Bugfix with custom free. Changed from "my" to "lodepng_"
    prefix for the custom allocators and made it possible with a new #define to
    use custom ones in your project without needing to change lodepng's code.
*) 28 jan 2013: Bugfix with color key.
*) 27 okt 2012: Tweaks in text chunk keyword length error handling.
*) 8 okt 2012 (!): Added new filter strategy (entropy) and new auto color mode.
    (no palette). Better deflate tree encoding. New compression tweak settings.
    Faster color conversions while decoding. Some internal cleanups.
*) 23 sep 2012: Reduced warnings in Visual Studio a little bit.
*) 1 sep 2012 (!): Removed #define's for giving custom (de)compression functions
    and made it work with function pointers instead.
*) 23 jun 2012: Added more filter strategies. Made it easier to use custom alloc
    and free functions and toggle #defines from compiler flags. Small fixes.
*) 6 may 2012 (!): Made plugging in custom zlib/deflate functions more flexible.
*) 22 apr 2012 (!): Made interface more consistent, renaming a lot. Removed
    redundant C++ codec classes. Reduced amount of structs. Everything changed,
    but it is cleaner now imho and functionality remains the same. Also fixed
    several bugs and shrunk the implementation code. Made new samples.
*) 6 nov 2011 (!): By default, the encoder now automatically chooses the best
    PNG color model and bit depth, based on the amount and type of colors of the
    raw image. For this, autoLeaveOutAlphaChannel replaced by auto_choose_color.
*) 9 okt 2011: simpler hash chain implementation for the encoder.
*) 8 sep 2011: lz77 encoder lazy matching instead of greedy matching.
*) 23 aug 2011: tweaked the zlib compression parameters after benchmarking.
    A bug with the PNG filtertype heuristic was fixed, so that it chooses much
    better ones (it's quite significant). A setting to do an experimental, slow,
    brute force search for PNG filter types is added.
*) 17 aug 2011 (!): changed some C zlib related function names.
*) 16 aug 2011: made the code less wide (max 120 characters per line).
*) 17 apr 2011: code cleanup. Bugfixes. Convert low to 16-bit per sample colors.

*) 11 dec 2010: encoding is made faster, based on suggestion by Peter Eastman
    to optimize long sequences of zeros.
*) 13 nov 2010: added LodePNG_InfoColor_hasPaletteAlpha and
    LodePNG_InfoColor_canHaveAlpha functions for convenience.
*) 7 nov 2010: added LodePNG_error_text function to get error code description.
*) 30 okt 2010: made decoding slightly faster
*) 26 okt 2010: (!) changed some C function and struct names (more consistent).
     Reorganized the documentation and the declaration order in the header.
*) 08 aug 2010: only changed some comments and external samples.
*) 05 jul 2010: fixed bug thanks to warnings in the new gcc version.
*) 14 mar 2010: fixed bug where too much memory was allocated for char buffers.
*) 02 sep 2008: fixed bug where it could create empty tree that linux apps could
    read by ignoring the problem but windows apps couldn't.
*) 06 jun 2008: added more error checks for out of memory cases.
*) 26 apr 2008: added a few more checks here and there to ensure more safety.
*) 06 mar 2008: crash with encoding of strings fixed
*) 02 feb 2008: support for international text chunks added (iTXt)
*) 23 jan 2008: small cleanups, and #defines to divide code in sections
*) 20 jan 2008: support for unknown chunks allowing using LodePNG for an editor.
*) 18 jan 2008: support for tIME and pHYs chunks added to encoder and decoder.
*) 17 jan 2008: ability to encode and decode compressed zTXt chunks added
    Also various fixes, such as in the deflate and the padding bits code.
*) 13 jan 2008: Added ability to encode Adam7-interlaced images. Improved
    filtering code of encoder.
*) 07 jan 2008: (!) changed LodePNG to use ISO C90 instead of C++. A
    C++ wrapper around this provides an interface almost identical to before.
    Having LodePNG be pure ISO C90 makes it more portable. The C and C++ code
    are together in these files but it works both for C and C++ compilers.
*) 29 dec 2007: (!) changed most integer types to unsigned int + other tweaks
*) 30 aug 2007: bug fixed which makes this Borland C++ compatible
*) 09 aug 2007: some VS2005 warnings removed again
*) 21 jul 2007: deflate code placed in new namespace separate from zlib code
*) 08 jun 2007: fixed bug with 2- and 4-bit color, and small interlaced images
*) 04 jun 2007: improved support for Visual Studio 2005: crash with accessing
    invalid std::vector element [0] fixed, and level 3 and 4 warnings removed
*) 02 jun 2007: made the encoder add a tag with version by default
*) 27 may 2007: zlib and png code separated (but still in the same file),
    simple encoder/decoder functions added for more simple usage cases
*) 19 may 2007: minor fixes, some code cleaning, new error added (error 69),
    moved some examples from here to lodepng_examples.cpp
*) 12 may 2007: palette decoding bug fixed
*) 24 apr 2007: changed the license from BSD to the zlib license
*) 11 mar 2007: very simple addition: ability to encode bKGD chunks.
*) 04 mar 2007: (!) tEXt chunk related fixes, and support for encoding
    palettized PNG images. Plus little interface change with palette and texts.
*) 03 mar 2007: Made it encode dynamic Huffman shorter with repeat codes.
    Fixed a bug where the end code of a block had length 0 in the Huffman tree.
*) 26 feb 2007: Huffman compression with dynamic trees (BTYPE 2) now implemented
    and supported by the encoder, resulting in smaller PNGs at the output.
*) 27 jan 2007: Made the Adler-32 test faster so that a timewaste is gone.
*) 24 jan 2007: gave encoder an error interface. Added color conversion from any
    greyscale type to 8-bit greyscale with or without alpha.
*) 21 jan 2007: (!) Totally changed the interface. It allows more color types
    to convert to and is more uniform. See the manual for how it works now.
*) 07 jan 2007: Some cleanup & fixes, and a few changes over the last days:
    encode/decode custom tEXt chunks, separate classes for zlib & deflate, and
    at last made the decoder give errors for incorrect Adler32 or Crc.
*) 01 jan 2007: Fixed bug with encoding PNGs with less than 8 bits per channel.
*) 29 dec 2006: Added support for encoding images without alpha channel, and
    cleaned out code as well as making certain parts faster.
*) 28 dec 2006: Added "Settings" to the encoder.
*) 26 dec 2006: The encoder now does LZ77 encoding and produces much smaller files now.
    Removed some code duplication in the decoder. Fixed little bug in an example.
*) 09 dec 2006: (!) Placed output parameters of public functions as first parameter.
    Fixed a bug of the decoder with 16-bit per color.
*) 15 okt 2006: Changed documentation structure
*) 09 okt 2006: Encoder class added. It encodes a valid PNG image from the
    given image buffer, however for now it's not compressed.
*) 08 sep 2006: (!) Changed to interface with a Decoder class
*) 30 jul 2006: (!) LodePNG_InfoPng , width and height are now retrieved in different
    way. Renamed decodePNG to decodePNGGeneric.
*) 29 jul 2006: (!) Changed the interface: image info is now returned as a
    struct of type LodePNG::LodePNG_Info, instead of a vector, which was a bit clumsy.
*) 28 jul 2006: Cleaned the code and added new error checks.
    Corrected terminology "deflate" into "inflate".
*) 23 jun 2006: Added SDL example in the documentation in the header, this
    example allows easy debugging by displaying the PNG and its transparency.
*) 22 jun 2006: (!) Changed way to obtain error value. Added
    loadFile function for convenience. Made decodePNG32 faster.
*) 21 jun 2006: (!) Changed type of info vector to unsigned.
    Changed position of palette in info vector. Fixed an important bug that
    happened on PNGs with an uncompressed block.
*) 16 jun 2006: Internally changed unsigned into unsigned where
    needed, and performed some optimizations.
*) 07 jun 2006: (!) Renamed functions to decodePNG and placed them
    in LodePNG namespace. Changed the order of the parameters. Rewrote the
    documentation in the header. Renamed files to lodepng.cpp and lodepng.h
*) 22 apr 2006: Optimized and improved some code
*) 07 sep 2005: (!) Changed to std::vector interface
*) 12 aug 2005: Initial release (C++, decoder only)

	note:
		There are two address forms used above.  The short form is just a

		"whatever address you receive this reponse from".  This lets us use
		the host OS to solve the problem of multiple host addresses (possibly
		with no routing between them); the host will use the right address
		when we reply to the inbound connection request.  The long from is
		a full address and port in a string.  It is used for returning the
		address of a server that is not running locally.

KEY BUTTONS

Continuous button event tracking is complicated by the fact that two different
input sources (say, mouse button 1 and the control key) can both press the
same button, but the button should only be released when both of the
pressing key have been released.

When a key event issues a button command (+forward, +attack, etc), it appends
its key number as a parameter to the command so it can be matched up with
the release.

state bit 0 is the current state of the key
state bit 1 is edge triggered on the up to down transition
state bit 2 is edge triggered on the down to up transition
