I still don't understand what the proper way to support high DPI 
displays is... In some places I see that using 
QApplication::setAttribute(Qt::AA_EnableHighDpiScaling) is for legacy 
applications that don't natively support it. Yet, if I don't use that, 
my applications are blurry.

The documentation is silent about this.
