In my experience Qt 4 looks good on HiDPI displays  - you get high resolution 
text and Mac style. QPainter and GraphicsView draws high resolution content 
(there seems to be an issue with cosmetic pens though) This is all tested with 
the emulated mode on a normal-dpi monitor.

Some caveats: OpenGL content is standard resolution. The app bundle/Info.plist 
generated by Qt seems to disable HiDPI support somehow. As a workaround build 
with CONFIG -= app_bundle or copy the executable out of the bundle and run it 
directly.

QIcon has had scale factor support on Mac since the talk was about non-integer 
scale factors. (2007?) Perhaps it will finally pay off :)
