  I agree. There are good reasons for wanting a negative radius to act
as the equivalent positive radius, as well as there are good reasons for
a sphere with negative radius to not to appear at all. Also one possible
interpretation would be that it would be the equivalent sphere with
positive radius, but inverted.
