        The index number of the polygon to start with extracting

        starting with nPolygonIndex (i.e. a total of
        getNumberOfPolygons() - nPolygonIndex polygons is extracted).

        The index of the point within the first polygon (that with the

        The index of the polygon to start point insertion with. This
        index must be in the range [0,numPolygons], and the insertion
        will take place <em>before</em> this position (i.e. when
