[Qgis-developer] QWT polar for qgis 3?

[Neumann, Andreas]

Hi, 

I vaguely remember that it is used to display the satellite
constellation of GPS receivers. Potentially also used by some Python
plugins. 

qwt and qwt-polars did cause quite a few troubles for me during
compiling in the past. 

Given that qt5 has a charting component that also includes polar charts
(http://doc.qt.io/qt-5/qtcharts-index.html), I would appreciate to get
rid of the qwtpolar dependency.
