HiDPI Support on macOS
On OSX with a HiDPI screen, OpenFlipper appears to be rendered at a low resolution and is then scaled up, resulting in a very pixelated look. I believe this is the effect of the magnified mode documented here:
Setting the plist entries for HiDPI support fixes this, however the OpenGL viewport is rendered at a quarter of the intended size.
I played around with the Qt enviroment variables documented at http://doc.qt.io/qt-5/highdpi.html , QT_SCALE_FACTOR=0.5 yields the correct OpenGL viewport size, at the cost of extremely tiny fonts everywhere.
My system is a 2017 13" MacBook Pro running High Sierra.
