Retina/HiDPI support for QUserView (that is a real show-stopper for me right now).
(this may be out dated?)

Is still an issue. Retina seems to be supported only for the main window, not for widgets. I'm not sure if windows with UserView are widgets internally, but they all still show the same bug in QT5 and OS 10.11.

For those who do graphics with sclang, this is quite an issue.

I found this hint: http://stackoverflow.com/questions/23985143/how-do-i-enable-hidpi-retina-support-in-a-qt4-opengl-application

QApplication::setGraphicsSystem("native");

But where to put it? Any hint?

once we are using a newer version of the Qt libs it will be worthwhile to revisit it.
