    Bug 760212 - method edit-stroke fails in version 2.9
    
    Need to keep GimpPDBContext's stroke options (which is a context too)
    in sync with the PDB context itself, so setting any of the context's
    properties properly affects subsquent strokes, and also avoids running
    into inconsistent states like happened in this bug.
