   QwtArray< QwtDoubleInterval > QwtClipper::clipCircle (const QwtDoubleRect
       &clipRect, const QwtDoublePoint ¢er, doubleradius) [static]
       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
