Are you sure? At least function exists.

Calculating sphere radius in algorithm is not so hard. But I need to define
sphere by hand. That's why it would be very helpfull to add new type of object
(real sphere), move and scale it, then get center and radius.

Dirty hack described in other post (about creating mesh sphere and taking its
radius/center) may work as temporary solution, but I wonder how hard it will be
to make it correctly. Is it possible by modyfing a little just Python API,
without moving into Blender internals? (Sorry if this question is stupid :)
