It would also be my own preference, if it wasn't for the technical

That's one of the problems.
The other is that I would need to attach the bounding information to the
function object in the first place.

You see, the whole function thing in POV-Ray is (at least to me) a black
box of equally black magic. The less I need to intrude there, the better.


(Of course that doesn't need to limit your brainstorming. Maybe the
issues happen to be less of an obstacle than I currently expect.)
