\brief A helper class for translating a series of points
QwtPointMapper is a collection of methods and optimizations
for translating a series of points into paint device coordinates.
It is used by QwtPlotCurve but might also be useful for
for translating a series of points into paint device coordinates.
It is used by QwtPlotCurve but might also be useful for
similar plot items displaying a QwtSeriesData<QPointF>.
