Follow-up Comment #44, bug #49053 (project octave):

@mtmiller I can fix all of those easily except the configure testing stuff. I
have no idea how that stuff works, nor the time/desire to figure it out. Can I
assume HAVE_QT5 is set or not set as it is already something in the configure
process?

Yes the devicePixelRatio is new since QT5, but both QApplication and QScreen
are available in QT4.8 (I'm not sure about <4.8).
