It shouldn't be too hard to implement this one, in theory. Basically, compute the min and max x, y, z coordinates over the vertices of the transformed mesh. The midpoint in the 3 coordinates will be the center, while the radius is the distance from the center to min(x, y, z) (or max(x, y, z), they should match).

I haven't checked that all that's required to get the transformed mesh is already in place, but at a quick look it looks like the basic functionality is there at least.
