code is still unused, but the intention is to use this to solve the double sided
lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0
eventually.
The code works and matches the fixed function lighting pretty much exactly, but
still needs optimizations. The actual integration in object draw will be
committed later when more fixing & testing, there's lots of different combinations
and unclear OpenGL state here.
* Shadow color now usable in the BGE
* Simplified the shadow panel while "Blender Game" renderer is active
* Added variance shadow maps for the BGE
* Buffered shadows on sun lamps in the BGE (orthographic)
* Light textures in the BGE
