> I'm drawing a couple of arcs and then calling ClosePath() to close up the shape I drew. This works great. But then I repeat the process in a different place, and stroke the whole thing. Unfortunately, Core Graphics adds a line from the last point in the closed path to the first point of the new arc I add. From my reading of the docs, this line shouldn't happen.
