class BezierSurface from PGeom inherits BoundedSurface from PGeom

        ---Purpose :   Defines a  rational  or  non  rational   Bezier
        --         surface.  In this package the  degree of the Bezier
        --         surface is limited to MaxDegree and must be greater
        --         or equal to 1.
        --
