Interesting... But is this case you are then fitting a scaled sphere
inside a scaled sphere bounding shape and telling me its faster
when its bound by a box.  What sort of shape would render
faster being bound by a sphere if its not a sphere?  It doesn't
sound like using a sphere as a bounding shape would be all that
useful.  I assume I'm missing something.
