  UV-mapping could be a way to do it if you can come up with a pattern
of the form described in chapter 6.7.7.1. I can't think of an easy way
of doing this right now...
  You could do it with six boxes, but that's not the only option.
  Using the intersection of six planes gives you a true box (which is
also usable in CSG) but can be a bit slower. You should definitely
remember to bound this "box" with a true box of the same size
(see bounded_by docs).
  You can also use the polygon or triangle primitives (the latter could
be inside a mesh, taking a bit less memory, I think), and it would be
faster to render but not usable in CSG (even though with a mesh you
can use inside_vector).
