[Development] Updated high-DPI support for Qt 5.14

[Mark De Wit]

Is there a chance that the high-dpi work will fix the dpi-awareness of the Fusion theme as reported in https://bugreports.qt.io/browse/QTBUG-74100 ?

Last time I checked there was a fair amount of drawing code that didn't check what screen a widget was on, and hence used "global" scaling (if any).
