Make QIcon generate high-dpi pixmaps.
QIcon::pixmap() can now return pixmaps that are larger
than the requested size, This is a behavior change
that may require updating existing application code,
and is enabled by setting Qt::AA_UseHighDPIIamges.
Add new pixmap() and actualSize() overloads that take
a window pointer. For 100% correctness you want to
target pixmap generation to a specific window, in
case the system has a mix of normal and high-dpi
displays. (The non-window versions uses QGuiApplication::
devicePixelRatio(), which returns the ratio for the
"best" display on the system.)
actualSize now returns the size in device-independent
pixels - not the pixmap pixel size. This matches
its intended use case which is layout calculations.
