Apricot Branch
==============
Various cleanups and optimizations in the game engine:
* Remove some duplication in the RAS_RenderTools, and sync the blender
and game player versions. Also avoid some opengl state changes.
* Don't make separate materials for triangles and quads, this distinction
was moved to the mesh level. Also don't take some other irrelevant tface
settings into account to avoid making more materials.
* Refactoring of mesh storage, should fix wrong normals on meshes that are
reused. It also allows for joining together nearby meshes for speed, though
that's disabled still because it doesn't work together correct yet with
ome features.
* Added a distinction for game objects to be either culled or set invisible,
previously there was only one flag, which couldn't work correct.
* For parenting to bones, where_is_pose was executed multiple times per
frame, now should be once per armature.
* Fix uninitialized intertia value in the physics system.
* Various warning fixes.
* Removed some conditionals in GLSL and other minor optimizations in the
code. Also cache opengl uniform locations, and fix an invalid memory read.
* Avoid doing some math for GLSL lamps if it is not required.
