One other question.  I've made a complicated CSG that takes days to render.
I'm trying to speed it up.  While making it I defined all my cylinders as
cones.  Would there be any gain in efficiency if I went back and replaced
all the cones with cylinders that I could?

Thanks,
Carl

No. If the radii are nearly identical (within EPSILON of each other), 
the cone will be converted into a cylinder.
