If a splitting line starts outside a polygon and ends inside it, the user should receive an error message. Instead, a vertex is added where the split line crosses the polygon border.

Yes, those are dangling lines and it would be good to have a C-API function for it. In the meantime, r9490 contains a fix for most cases without using the dangling line function of polygonizer. I'm therefore closing this ticket.

Are those dangling lines? the geos polygonizer also has a method without C-API for that. If it is, we should propose a function for it, too.
