Will the bounding box of a CSG intersection be the intersection of the 
bounding boxes of it's components, or will it be the union of them?  Or 
something else entirely?

The reason I ask is that I'm taking relatively small 'slices' of basic 
constructs using an intersection with a thin box, and I want to know if 
the resultant bounding box will be the optimal area where the bounding 
box of the construct intersects with the bounding box of the box used to 
slice it up.  If not, I can manually calculate the bounding box and 
apply it fairly easily, I'd just rather not do that if POV already does 
it for me.
