MarlinRenderingEngine.createStrokedShape: Getting offset to original shape bounds

[ThisOtterBeGood]

Is there any way to retrieve the offset of the bounds of the original shape within the generated stroked shape? See the following illustration:

In other words: If you overlay the original shape onto the stroked shape, what is the offset of these? (black vector)

The Engine should have that information somewhere inside but i cannot find it. Probably somewhere within the sun.java2d.marlin.Stroker.

The return value actually contains the offset within x and y of the resulting shape.
