Detailed Description
       QwtPolarPanner provides panning of a polar plot canvas.

       QwtPolarPanner is a panner for a QwtPolarCanvas, that adjusts the
       visible area after dropping the canvas on its new position.

       Together with QwtPolarMagnifier individual ways of navigating on a
       QwtPolarPlot widget can be implemented easily.
