Juergen E. Fischer 33fc476d89 * replace external qwtpolar with qwt 6.3
* require qwt >=6.2 (and fallback to internal 6.3 if system's qwt doesn't suffice)
* debian doesn't have qwt for Qt6 and won't have it for trixie

\brief QwtPlotPanner provides panning of a plot canvas
QwtPlotPanner is a panner for a plot canvas, 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
