fteqw/engine/client/r_surf.c
Spoike 9cd425e945 rework hlmdl subblends. apparently they're some sort of grid. 
fix decals again. clampmap should work properly with them, also removed the extra part.
fix rtlight pvs issue with respect to portals
fix vid_reload causing the d3d9 renderer to use nearest sampling
terrain system should now mostly work with d3d9. still has issues.
fix q3 volumetric fog not applying to models
