Added automatic graphicssystem switching on meego when app is minimized.
When all top-level widgets are minimized we switch to raster to reduce GPU memory consumption. We switch back to graphicssystem meego when at least one top-level widget is shown normally again. The switching only applies when the runtime graphicssystem is being used. The switching only applies when the runtime graphicssystem is being used. Task-number: QTBUG-18013 Reviewed-by: Armin Berres
