Fix for poor performance during screen orientation switch
Processing the relayout takes longer than 100ms. Setting priority to low makes the app wait until all other apps have been processed before it gets scheduled again (over 3 seconds). By setting priority to background, the app is round-robin scheduled with the other apps (in 20ms timeslices) Task-number: QT-1030 Reviewed-by: axis
