This primitive draw method draws a PolyPolyline. In case of PolygonMode = line, simple lines are drawn. If PolygonMode = Fill, a filled area bounded by lines is drawn. The Loxyz must have the property that the entries are coherent xyzarrays and in addition to that, there are no cross points. If this is done, the xyzarrays, which lay in an other filled xyzarray are "drawn as hole". If it lays in a hole, the xyzarray is filled out?.
