Addendum:
The patch tests only additional boundings, that is only when 'bounded_by'
is used. So the effect on everyday-scenes will likely be small. It could be
extended to test the automatic-generated BoundingBox as well. But
unfortunately POV-Ray does not generate a boundingbox-hirarchy with
merge/intersections.. I do not really see why.
