    Ensure that the clipping path is reset when the state is restored (issue 6413)
    
    According to the specification, see `NOTE 2` in http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.3882161, it appears that we should ensure that the clipping path is reset when the restore (`Q`) operator is encountered.
    
    Fixes 6413.
