Translate the whole object so the sphere center is at the origin, then
rotate, then translate back to position.
This is often a common misunderstanding with newer POVers.  All transforms
are performed relative to the origin <0,0,0>, rotate, scale and even
translate (though it's generally ambiguous with translate).
