$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. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4868 fc73d0e0-1445-4013-8a0c-d673dee63da5
