fteqw/engine/gl/gl_vidnt.c
Spoike 5b0843e0c7 split up NOMEDIA into individual defines. The Wastes should now be able to do music now. 
tweak rtlights a bit, to not bug out on The Waste's decals.
use compatibility glsl in order to get ftransform working for consistent vertex coords (still uses core if there's no fixed function stuff). this fixes z-fighting issues with rtlights.
Rework punchangles for greater compatibility.
