Fixed absorption of photons and rays

I fixed some simple bugs in the absorption of photons and along rays 6 months ago. The first image is from a debugging session for this. Second image shows a cognac glass with fixed absorption, and also  a text label in the bottom right corner that is automatically added now. The rather hideous texture is something I made in Gimp.

I abandoned my triangle-only architecture and moved to a more flexible one using inheritance. Of course I have Primitive::TriangleMesh, but here is a Primitive::Instance(Primitive::Sphere) which means its an instance of sphere, where the instancing’s matrix is used to store the ellipsoid transformation. I guess this must be the most boring instancing image ever created. Still, it’s an achievement!
