min_extent and max_extent only return the size of the current bounding
box, which is not necessarily the smallest box that surrounds the object.
So your sample code is meaningless; it won't put any tighter bounds on the
object than already exist.  If your object is an isosurface, min_extent
and max_extent will likely return the bounding box of the contained_by
object or of the bounded_by object if one was specified.
