Subject: [PATCH] ImageViewer can now be closed by clicking into the empty
 space

This is disabled on mobile devices due to the lack of precision when tapping on a spot, preventing accidental closing. In general this is not really required on mobile devices because the close button is rather big and easily reachable with a minimum of finger movement.
