    plug-ins: in screenshot, keep image dirty; keep history clean
    
    In the screenshot plug-in, don't clean the image, since it's not
    backed by any persistent source, and disable undo while modifying
    it, so that the initial edit history is clean.
    
    (cherry picked from commit 4fe821789805a2665961fdded047c66ad78a98ad)
