Detailed Description

       A base class for plot print filters.

       A print filter can be used to customize QwtPlot::print().

       Deprecated
           In Qwt 5.0 the design of QwtPlot allows/recommends writing individual QwtPlotItems,
           that are not known to QwtPlotPrintFilter. So this concept is outdated and
           QwtPlotPrintFilter will be removed/replaced in Qwt 6.x.
