You could vtransform() a point as you transform the object

If you make the small object a sphere centered on the point you're trying to
follow, the center of its bounding box will be on the transformed point.
But min_extent and max_extent work with #declared objects, which means they
won't work with a piece of a CSG as you want. I know there was some talk
of being able to extract the transformation matrix from an object, but I
don't know if anyone ever wrote that patch.
