libSDLmain.a has to be linked and must run anyways. So there's no need
for us to reinvent the wheel, just rely on SDLs process setup, argument
parsing, message handling and so on. As a nice side effect this may fix
some strange bugs related to message handling and argument parsing...
It's not stb.h and the github project should probably be linked
And now the licensing is a bit more verbose (Dual-Licensed under Unlicense and MIT
instead of custom Public Domain license).
My modifications (jpeg writing and supplying zlib compressor for better
PNG compression) have been merged upstream, so from now on updates
should be easy and painless.
(Sean renamed my stbi_png_level to stbi_write_png_compression_level)
Until now we had 3 modes:
0 -> never grab the mouse.
1 -> always grab the mouse
2 -> ungrab the mouse if the game is windowed and the console or the
menu is opened or a cinematic is playing.
The 3rd mode is the same as the 2nd one, but without the "game is
windowed" constrained. Please note that release the mouse grab in
fullscreen may have side effects like the game loosing focus and being
unable to regain it. Especially under X11.
This was requested by @prg318 in issue #271.
Loop 'for ( i = 0; i < 3; i++ )' sets values to vtx[0..2]. So next index must be 3(instead 4) and
loop 'for ( i = 16; i >= 0; i-- )' will set vtx[3..(18*3-1)].

Apparently something (possibly nvidia's driver) on some windows
installations has some stupid application profile for quake2.exe that
breaks mouse input if the console has been opened..
Our workaround is to rename quake2.exe to yquake2.exe and provide a wrapper
quake2.exe that just calls the real one for backwards compatibility.
This is the source of that wrapper.
This is mostly the same approach as in GL1. I'm not quite sure if the
software rasterizer can work with all aspects and the like but I wasn't
able to crash it by trying several random resultions.
