Does this manifest on that other platform that now offers extra high
resolution displays (a.k.a. "Retina") i.e. MacOS?

If we go for the solution involving:
"QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);" we will
need to wrap it in "#if QT_VERSION >= 0x050600"..."#endif" so it doesn't
throw a complier error on older versions (e.g. the 5.0.2 that is used by
the Travis C.I. system for Linux testing)...
