    meta-window-actor: Don't unredirect shaped windows
    
    If a window has its BoundingRegion shaped, we shouldn't unredirect it,
    as it expects the rest of the windows from being shown under it. This
    prevents applications like the Skype screen recorder or gtkRecordMyDesktop
    which want to show a "border" around the recorded area from being
    unredirected, giving the appearance of making the desktop freeze.
