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