    tdf#120797: Apply transformation also to the extents of damage
    
    since 7034311dce663c895577267110baadbec312d491 affine transformation
    is passed down to drawPolyPolygon and drawPolyLine functions.
    
    The transformation was correctly applied to cairo context, but not
    the extents of damage so those had old, untransformed coordinates and
    were therefore not redrawn
