Implement high-dpi "@2x" image handling. Make QQuickBaseImage::load() load "@2x" image files on high-dpi displays. Reload images on screen change in order to load the correct version depending on screen dpi. Modify QQuickImageBase::updatePaintNode() to work with @2x images. QQuickBaseImage::load() now looks at the target window's devicePixelRatio and checks for the presence of a "@2x" file on disk. If found the @2x version will be used. Unlike QPixmap, QQuickPixmap has no special knowledge of "@2x" files. They pixmap system will be asked to load "@2x" files and will cache them and report the (device) pixel size, like any other pixmap. Add auto-test and manual test.
