Scale up OrientedBoundingBox

Maybe I gave too much info?

have you tried just increasing the extents of the OBB?

No, that would, as usual, be too obvious for me.  I was stuck on the idea of making it work on BoundingVolume because it could be a BoundingBox, OrientedBoundingBox, or BoundingSphere, all of which have transform.

It works great to modify extents on OBB, thanks!  The point picking is much more friendly that way.

I'd still like to understand what I'm doing wrong with transform though.
