Actually, this is not new to MegaPov. Let me explain:
Isosurface intersection computation is _always_ bounded. I don't know how
the intersection is performed, but I do know that it can only happen over a
finite volume using the current implementation(s).
Prior to MegaPov 0.4, this computational boundary was defined using
"bounded_by". Unfortunately, this caused a conflict with the original
"bounded_by", which has a totally different meaning when applied to any
object other than an isosurface. And to make things worse, depending on the
order in which you applied the "bounded_by" keyword and the other modifiers
(such as "translate"), you could make it either change the computational
container or change the ray-bound object (the way the original bounded_by
works).
Therefore, we had to change the syntax to remove this conflict.
