The PrimitiveRep class implements the primitive modeling type base class.
NOTE : the draw operator was removed. We will assume that rendering toolkits would have an implementation for drawing the primitives rather. NOTE: would it be nice to store the bbox ? NOTE: the intersect method was commented out as does not seem to have a possible generic signature ???
