Before such a change makes into a future megapov version or official
POV-Ray it should be intensely checked if the new code works as good as
the old one.  The old intersection test does not work perfectly in all
situations and your method could possible be worse (or better of course).

BTW, for speed reasons an isosurface superellipsoid is usually faster than
a native one.
