  As I said, that's extremely difficult to implement for any given object.
Of course it's trivial for spheres, but if you want to support any object,
you are approximating the impossible.

:     Extents(intersection { object { A } object { B } }, Min, Max)

  Note that even if the bounding boxes of the objects intersect, that doesn't
mean that the objects themselves do.

: It appears to work with primatives

  Again that word...
