        /** SdrLathePrimitive3D class

            This 3D primitive expands the SdrPrimitive3D to a 3D rotation definition.
            The given 2D tools::PolyPolygon geometry is imagined as lying on the XY-plane in 3D
            and gets rotated around the Y-Axis.

            Various possibilities e.g. for creating diagonals (edge roudings in 3D)
            and similar are given.

            The decomposition will create all necessary 3D planes for visualisation.
