+ This 3D primitive expands the SdrPrimitive3D to a 3D extrude definition.
+ The given 2D tools::PolyPolygon geometry is imagined as lying on the XY-plane in 3D
+ and gets extruded in Z-Direction by Depth.
+
+ 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.
