  Rene, just an idea ( I was thinking about GL implementation of this 
class).
 the Sphere is just a TPcon with the ZERO inner tube diameter for 
all parts/divisions.  Could we adopt such sort of the definiton for 
"la quadrature du  cercle"  for a while. It is quite easy to 
implement and will make sense for OpenGL view right away.
