The polygons are filled using the current AREABUNDLE structure values. For the first polygon, the current position is the first point. For all subsequent polygons, all points that define the polygon are given explicitly. The polygons are automatically closed, if necessary, by drawing a line from the last vertex to the first. Notice that polygons can overlap, if needed.

Note: GrePolygonSet is not valid when the COM_AREA or COM_PATH flag is set.
