Right, but the transformation of the polygonal envelope of the original
box3d, is not necessarily going to be rectangular - so, by translating the
two corners of the box, to create a new box, you are losing some
information... all the more reason to force boxes into polygons before doing
things with them, as Paul has suggested.
