    Description

      QPainter with Qt::SmoothPixmapTransform scales down images badly. The quality is the same as when we are scaling via QPixmap with Qt::FastTransformation.

      QPainter is used to scale images for QtWebKit, so there is no clean way to scale down image with normal quality in HTML. See QTBUG-30155

      Take a look at attached program and screen.
