Detailed Description

Transforms a polygon with holes into a single self-touching (invalid) ring by connecting holes to the exterior shell or to another hole. The holes are added from the lowest upwards. As the resulting shell develops, a hole might be added to what was originally another hole.

There is no attempt to optimize the quality of the join lines. In particular, a hole which already touches at a vertex may be joined at a different vertex.
