Hmm, not what I expected. I would have thought that finding an 
intersection against 12 planes and clipping them to triangles would be 
slower than intersecting 6 planes...maybe the mesh bounding is making 
more of a difference than I thought, or maybe intersection has more 
overhead than I thought.

Hmm, maybe a union of 6 clipped planes would be faster. Bound each plane 
individually, so POV can eliminate the faces...
