The type of effect he's going for probably will end up requiring CSG,
and then he'll need inside_vector.  Inside_vector lets POV know where
the inside of a mesh is.

If you have two surfaces, a front and a rear, and you wish for refraction
to happen on them, one solution is for both of those surfaces to be
part of the same closed object assembled with CSG.
