When partly moved back and forth between screens
with different dprs (device pixel ratios)
unexpected jumps and size changes could occur.
(See the linked issue for details)
This patch maps global coordinates to native ones
and vice versa (in QDockWidgetPrivate::mouseMoveEvent()),
so that the calculated position is the right coordinate
on the right screen.
