I should have known of course, and instead of swearing by Eagle the 
Bald, sacrificing nameless things to the Clipka idol and invoking the 
good spirit of Saint William of the Pokorny (in that order) for a couple 
of days, I should have opened the Grimoire and read:

"Note: This is not perfect, in some cases (such as CSG intersections and 
differences or isosurfaces) the bounding box does not represent the 
actual dimensions of the object."

The hell it doesn't!

So, I am left with the good old trial-and-error finding of the right 
dimensions/locations of intersection objects. Not a big deal afaiac ;-)

Still, I have been wondering if there would be other, smart, ways to do 
the same? And - just out of pure curiosity - why do min_extent and 
max_extent not work with intersections or differences? Where isosurfaces 
are concerned, I can imagine indeed...
