High-DPI: Enable AA_UseHighDpiPixmaps by default
The effect of this is that QIcon::pixmap() will/may
return a pixmap larger than the requested size (with
an appropriate devicePixelRatio set), suitable for
high-dpi displays.
Many use cases, such as painting the image with QPainter,
will be unaffected by this change. User code which e.g.
iterate over image pixels may have to be updated.
