Title: Add punch holes

@hsanchez

Now there is one punch hole for each vertex most of the times. In a second thought about adjusting the hole when the algorithm fails in those corn cases, as far as I can image, the place near the vertex is too thin to punch any holes at all wherever I adjust the hole. So we'd better not punch any holes for those vertices. This is what this pull request does.
