            [Qt] Path::normalAngleAtLength() returns incorrect value on ACID3.
    
            QPainterPath returns angle values with the origo being at the top left corner,
            we need to account for this in normalAngleAtLength().
            This Regressed with r66979.
    
            No new tests as this is already covered by ACID3.
