Good.

If you'd like unshaded spheres in general (in 3D parlance, they're  
"unlit"), the default for Sphere3D should be unlit colored spheres.   
They're only lit in balls3D because of the code in BallPortrayal3D  
(check it out).

CubePortrayal3D's not a subclass yet because Gabriel is deciding  
whether or not to get rid of it and just collapse to BoxPortrayal3D.   
Gabriel?
