Log Message:
-----------
Basic shader now runs and renders lit objects on OpenGL 3.2 Core.
The lighting isn't accurate yet. Lots of glitches.
On another note, Vertex Array Objects may not be as useful as I thought they'd be for saving immediate mode state.
Had to work around a bug in ATI drivers that makes attribute 0 not work when changed with glVertexAttrib.
