    fixed the video player stopping after saving a screenshot
    
    Do not update the orientation if it didn't really changed, sometimes a
    'changed::viewer-thumbnails-orientation' signal is emitted even if the user
    didn't change anything, I'm not sure why.  This caused the video player to
    be unrealized and relealized again.
