Well I wasn't thinking of fully supporting all of povray's stuff like
some of the different light types that don't have a native equivelent in
opengl. And then, there's transparency, reflections, refractions,
povray's function-textures, media, imagemaps, and maybe a few more
I havn't thought of.

In order to get camera position and angle, there would need to be a way
to output the current values that the camera has which would make opengl
rendering even more different than povray raytracing. I think, if I do
actually start building it, that I'd try to mimic the behavior of native
rendering as much as possible. For me, this is all just talk so far. I'd
love to do it, but I'm not sure I will.
