Triangulating ngons could fail with the method that was being used: projecting along the dominant normal axis and then using CDT. It could fail if the ngon has self crossings or might be so after the described projection. Switched to using projection along the normal itself, and also to using polyfill which produces some kind of triangulation no matter what in such circumstances. This will also likely be faster if there are a lot of ngons in the meshes, since the exact arithmetic CDT was being used before, and now float arithmetic is used.
