Hello, I have a question for metapost specialists: I am looking for some sort of effect, built upon a zig-zag line. The first graphic in the minimal example below is as I would expect. The second graphic seems to be drawn without the point at (0,0). (Ignore the asymmetry at the end of the path in the 2nd, this is to be expected in this minimal example.) Is the result correct or is this a bug?
