fteqw/engine/sw/sw_rast.c
Spoike 9dbf5b5837 changed to not load gamecode from quake paths, to avoid issues with buggy quakeworld clients that will freely download stuff from anywhere (not sure what to do about ktx, but it can be reenabled with a cvar). 
image_width is now only set by a single function.
tweaked scancode inputs slightly. added support for printscreen binds.
changed the way gamma works. glsl gamma now used when running windows, or hardware gamma is not available. removed gl_contrast+gl_brightness.
q2 gamecode support no longer has a system componant. this means that ports only need the generic stuff.
misc tweaks to the d3d11 renderer.
added brief descriptions to many builtins. need to add comments to constants, globals, and fields too, somehow.

Our software rendering basically works like this:
main thread builds command:
command contains vertex data in the command block
main thread runs the vertex programs (much like q3) and performs matrix transforms (much like d3d)
worker threads read each command sequentially:
clip to viewport
division of labour between worker threads works by interlacing.
each thread gets a different set of scanlines to render.
we can also trivially implement interlacing with this method
