    screenshot: Hide cursor while magnifier is active
    
    As with the screen recorder, the magnifier already adds its own
    copy of the system cursor, so we should not add it again. Just
    as in the screen recorder case, we don't address the case where
    the cursor should not be included in the screenshot, but the
    magnifier adds it anyway.
