  30             HatchTexturePrimitive3D is derived from GroupPrimitive3D, but implements
  31             a decomposition which is complicated enough for buffering. Since the group
  32             primitive has no default buffering, it is necessary here to add a local
  33             buffering mechanism for the decomposition
