       Circle clipping
       clipCircle() devides a circle into intervals of angles representing arcs of the circle. When the circle is completely inside the clip
       rectangle an interval [0.0, 2 * M_PI] is returned.

       Parameters:
	   clipRect Clip rectangle
	   center Center of the circle
	   radius Radius of the circle

       Returns:
	   Arcs of the circle

   QwtPolygon QwtClipper::clipPolygon (const QRect &clipRect, const QwtPolygon &polygon) [static] Sutherland-Hodgman polygon clipping
       Parameters:
	   clipRect Clip rectangle
	   polygon Polygon

       Returns:
	   Clipped polygon

   QwtPolygonF QwtClipper::clipPolygonF (const QwtDoubleRect &clipRect, const QwtPolygonF &polygon) [static] Sutherland-Hodgman polygon clipping
       Parameters:
	   clipRect Clip rectangle
	   polygon Polygon

       Returns:
	   Clipped polygon
