Removes vertices:

Vertices are semi-adjacent when they are separated by a single (out-lying) vertex.

The distance parameter's default value is approximately √2 so that a vertex will be removed when adjacent or semi-adjacent vertices having their corresponding X and Y coordinates differing by no more than 1 unit. (If the egdes are semi-adjacent the out-lying vertex will be removed too.)

C++ only: This function is overloaded. In the first definition, the in_polys and out_polys parameters can reference the same Paths object though in that case the calling code might be clearer if the second definition (accepting a single Paths parameter) is used.
