\brief QwtPlotPanner provides panning of a plot canvas
QwtPlotPanner is a panner for a QwtPlotCanvas, that
adjusts the scales of the axes after dropping
the canvas on its new position.
Together with QwtPlotZoomer and QwtPlotMagnifier powerful ways
of navigating on a QwtPlot widget can be implemented easily.
\note The axes are not updated, while dragging the canvas
