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_poly and out_poly parameters can reference the same Path object though in that case the calling code might be clearer if the second definition (accepting a single Paths parameter) is used.
