        5 test cases updated, no additional tests needed.

        Removed KCPathData, KCPathDataList and KCanvasUserData.
        Added KCanvasPath and KCanvasPathQuartz instead.
        Updated methods to expect KCanvasPath* types and use RefPtr.
        Removed no longer needed KCPathDataList -> KCanvasUserData routines
