      Description

      QPixmapIconEngine::paint calls qt_effective_device_pixel_ratio with window = 0, which qApp->devicePixelRatio

      This results in down-scaled retina images used on non-retina screens, which looks quite ugly.

      With patch applied the device aspect ratio is taken from painter instead.
