Add Qt::AA_UseHighDpiPixmaps.
Setting this attribute enables QIcon::pixmap() to return
high-dpi pixmaps when running on "retina" type displays.
This requires an opt-in flag since the returned pixmap
can be larger than the requested size, which is a change
in previous documented behaviour that can break existing
code.
