[JAVA2D] How do you calculate more exact bounds for a shape?

[Daniel]

Given a GeneralPath with various line/quad/curve nodes, how do you calculate the bounds of the shape? The getBounds2D method returns a value that includes the location of the control points. Various bugs have been reported and all seem closed as not a bug. One (I can't recall the bug number) had a workaround "calculate it yourself". Unfortunately, I don't know how.
