  \brief QwtPlotMagnifier provides zooming, by magnifying in steps.

  Using QwtPlotMagnifier a plot can be zoomed in/out in steps using
  keys, the mouse wheel or moving a mouse button in vertical direction.

  Together with QwtPlotZoomer and QwtPlotPanner it is possible to implement
  individual and powerful navigation of the plot canvas.
