This reverts 59bbfb17db563d7e62b9f3158dab3cc6e7e68acd and c853054910552f5fef04797222dde0d29a0c340d, as that approach was causing issues for QCommonStyle::iconFromWindowsTheme, for example in situations where the system has a 1x and 2.5x screen, and the user requests a 16x16 pixmap or icon via QStyle::standardPixmap or QStyle::standardIcon. In that situation our smallest pixmap is 40x40, and we need to downscale, causing blurred results on a 1x screen.
