       Some clipping algorithms.

QVector<QwtInterval>QwtClipper::clipCircle(constQRectF&clipRect,constQPointF&center,doubleradius)[static]
       Circle clipping

       clipCircle() divides 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

   QPolygonQwtClipper::clipPolygon(constQRect&clipRect,constQPolygon&polygon,boolclosePolygon=false)[static]
       Sutherland-Hodgman polygon clipping

       Parameters:clipRect Clip rectangle
           polygon Polygon
           closePolygon True, when the polygon is closed

       Returns:
           Clipped polygon

   QPolygonQwtClipper::clipPolygon(constQRectF&clipRect,constQPolygon&polygon,boolclosePolygon=false)[static]
       Sutherland-Hodgman polygon clipping

       Parameters:clipRect Clip rectangle
           polygon Polygon
           closePolygon True, when the polygon is closed

       Returns:
           Clipped polygon

   QPolygonFQwtClipper::clipPolygonF(constQRectF&clipRect,constQPolygonF&polygon,boolclosePolygon=false)[static]
       Sutherland-Hodgman polygon clipping

       Parameters:clipRect Clip rectangle
           polygon Polygon
           closePolygon True, when the polygon is closed

       Returns:
           Clipped polygon
