The intention is to return a minimal set.

Yes, the documentation indicates a set, which implies unique elements (except, I guess, for the first/last point, as per the GGL "way").

Instead of simplify you can also call std::unique (as in one of the samples) on the rings of the output polygons, this will help (but  I agree, inconvenient now).

Yes, it is easy enough to work around, once you know that it may be necessary. :-) Thanks! Jon
