D12405: [WIP] Per-screen scale factors on X11 using QT_SCREEN_SCALE_FACTORS

[Carlos Pita]

  I'm not testing the proposed patch per se, but if it's only about  setting QT_SCREEN_SCALE_FACTORS it doesn't work for me as I would have expected.
  
  I have two screens, my laptop requires 2x scale, the external monitor requires about 1.7x.
  
  So I set QT_SCREEN_SCALE_FACTORS='eDP-1=2;DP-2=1.7;'. But consider:
  
  1. QT_AUTO_SCREEN_SCALE_FACTOR=1 QT_SCREEN_SCALE_FACTORS='eDP-1=2;DP-2=1.7;' konsole
  
  2. QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCREEN_SCALE_FACTORS='eDP-1=2;DP-2=1.7;' konsole
  
  The first one correctly reduces the size of konsole (menubar, text inside the terminal emulator). The second one does nothing at all.
  
  So since plasma seems to be deliveratelt setting QT_AUTO_SCREEN_SCALE_FACTOR=0, I don't see how this would possibly work.
