38             This primitive allows filling a given PolyPolygon with a pattern
39             defined by a sequence of primitives which are mapped to  the unit range.
40             The pattern is defined using a reference range which defines a rectangular
41             area relative to the PolyPolygon (in unit coordinates) which is virtually
42             infinitely repeated.
