3 tiers of GL support:
* No GL: Only the raytracer is used.
* Minimal GL: GL is used only for wireframe rendering (everything else is handled by the raytracer). Criteria for Minimal GL is GL 1.2 and support of frame buffer object.
* Full GL: Everything (rendering/shading/painting) is handled by GL. Criteria for Full GL is GL 1.4, support of Frame Buffer Object, Vertex/Fragment Programs, Cg profile at least ARBVP1/ARBFP1 and all the shaders compiling successfully.
