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.
"After closing the subpath, your application can begin a new subpath without first calling CGContextMoveToPoint. In this case, a new subpath is implicitly created with a starting and current point equal to the previous subpath’s starting point."
Now, the AddArc() docs do say it might be preceded by a straight line segment, but when the context first starts, there is no starting position; I wonder why the subpath doesn't behave the same way after ClosePath().
iOS 6.1.3, iPad simulator or device.
