Apricot Branch: GLSL
====================
* Added initial support for shadow buffers, works in the 3d view and the
game engine, but has known issues still:
* Shadow buffers are made again for each 3d viewport unnecessarily.
* No filtering.
* There was a bug with some shaders going black, but can't reproduce
it anymore?
* Added support for layer lamps, though they're still always computed
in the shader, this needs to be optimized.
* Added support for animating lamp position/rotation in the game engine.
* Fix issue with lamps giving negative light on the backside.
* Fix issue with specular + orthographic camera.
* Fix square spotlights.
* Potential workaround for a bug in the nvidia drivers with shader linking.
