Geometry::CutElem

Makes pieces of a 2D primitive which are inside the cutting polygon.

     void CutElem (
       const Polygon2DData*     pCutPoly,
       short                    typ,
       const Sector*            pSector,
       const GenArc*            pGenArc,
       long                     nCoords,
       const Coord*             pCoords,
       const DirType*           pDirs,
       const unsigned long*     pVertInds,
       long                     nArcs,
       const PolyArcRec*        pArcs,
