AbstractThumbnailItem inherits from QQuickPaintedItem using QPainter to do the fallback painting of icons. The scene is adjusted to get the information from QQuickItem instead of QDeclarativeItem. Clipping got a little bit more complex as the clip path does not exist any more. To get it right the ThumbnailItem needs to specify the parent it wants to be clipped to with the clipTo property. E.g.: clipTo: listView The scene uses this clipTo parent item to correctly calculate the clip region. Also the ThumbnailItem needs to have clipping enabled. Note: this commit currently breaks TabBox as the qml and view are not yet adjusted. In scripting the export of the item is disabled, but any qml script using a ThumbnailItem would obviously also fail.
