Hmm, this could also be the reason why unions of simple objects show 'strange'
visual behavior, when they are scaled down way below 1 unit. (I've since taken
to making sure that I avoid 'small' scaling of objects--by boosting the scale
of *everything* in a scene; I think I've read something about this in the
newsgroups as well.)

Does that apply only to the 'new' bounding method in the 3.7 betas?  Or to 3.6.1
as well?

So do I take it that by turning Bounding=off, there's still an 'internal'
bounding mechanism at play (at least with meshes)? That's new to me; didn't
know that.
