fteqw/engine/gl/gl_rmisc.c
Spoike 2afefb77ca reworked the shader system slightly. 
$diffuse can now sample animmaps correctly (although this only makes sense when using glsl or replacement shaders (read: rtlights)).
$fullbright now defaults according to the animmap too.
added reflectcube and reflectmask (the latter defaults according to map/animmap, the former needs to be explicitly stated).
fix d3d9+d3d11 renderers a little. needs much more work.
