With all that CSG this scene is really slow without radiosity but it gave me
an idea. A few years ago I created a patch that allows the definition of
arbitrary points in an area light which could be used to create things like
light domes. I completely abadoned it but I am currently rendering this
scene with it to see how it might compare in terms of rendering speed and
quality for a scene with a recursion limit of only 1. I will post the result
in p.b.i when done since it is getting off-topic for this group.
