  34
  35             This 3D primitive expands the SdrPrimitive3D to a 3D extrude definition.
  36             The given 2D tools::PolyPolygon geometry is imagined as lying on the XY-plane in 3D
  37             and gets extruded in Z-Direction by Depth.
  38
  39             Various possibilities e.g. for creating diagonals (edge roudings in 3D)
  40             and similar are given.
  41
  42             The decomposition will create all necessary 3D planes for visualisation.
