	fetchLightSource:ofObject: Fetch the primitive light source from the given array. Note: No checks are done within here - that happened in stackLightArrayValue:
	stackLightArrayValue: Load an Array of B3DPrimitiveLights from the given stack index
	stackMaterialValue: Load a B3DMaterial from the given stack index

	b3dShadeVertexBuffer Primitive. Shade all the vertices in the vertex buffer using the given array of primitive light sources. Return true on success.
	b3dShaderVersion Return the current shader version.

	addPart:from:trackFlag:scale: Add the given light part to the output color, scaled by the given scale factor. If the given flag is set in vbFlags then load the part from the primitive vertex
	computeAttenuation Compute the attenuation for the current light and vertex
	computeDirection Compute the direction for the current light and vertex
	computeSpecularDirection Computes l2vSpecDir _ l2vSpecDir - vtx position safelyNormalized.
