/** SdrLathePrimitive3D class
This 3D primitive expands the SdrPrimitive3D to a 3D rotation definition.
The given 2D 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.
