	Create lights out of patches and lights.
void	BuildPatches (void)
	Create surface fragments for light-emitting surfaces so that light sources may be computed along them. This function is responsible for one.
void	SubdividePatches (void)
	Iterate all of the head face patches, subdividing them as necessary.
void	CalcTextureReflectivity (void)
