Martin Gräßlin 19d567ef7f [kcm-kwintabbox] Use QQuickItem for Thumbnail instead of QQuickPaintedItem
We are only rendering an image, so it's better to load the image into a
texture. This allows to properly scale the example preview which
magically fixes all the layouting problems which used to be there.
