pfSphereContainsPt on the 8 vertices may not do, because the sphere may
intersect a volume of the box in between vertices in which case it would
intersect a plane or an edge without containing any of vertices. I think
pfSphereContainsBox may have to be done by testing sphere intersection with
planes from the faces of the box. It would be a really useful function.
Thanks,
Gan
