Re: [CsMain] Reflectivity of a surface

Well, my thinking is that we're facing a problem where shaders in interactive rendering are designed to assign a single pixel color, whereas "shaders" in raytracing also have the responsibility of representing the distribution of light from any surface.  So, they're kind of the same, but achieved in different ways.

Now, that said, I think lighter2 is separate, and could be used *only* in the raytracing context, since its being used to generate maps offline.  My thinking is that we should be using the most physically realistic method possible, which would be to specify the full BRDF for each surface.  Now, probably we should provide some basic BRDFs for folks who don't want to generate a unique one and just want to use, say, the Ward model.

I'm not sure this is overly complex, but it might be outside the scope of the SoC project.
