#207 Union fails

[Terence_13]

Union of 3-P.txt with 3-Q.txt or union of 2-P.txt with 2-Q.txt fails to create a one-path solution using Clipper2. Same input in clipper gives correct single path solution.

Command for clipper: clipper_console_demo.exe "3-P.txt" "3-Q.txt" UNION NONZERO NONZERO

(used for clipper2 exact same same console demo wrapped around the unmodified clipper2 library, newest sandbox version):

Note: There's currently no guarantee that polygons will be strictly simple since 'simplifying' is still a work in progress.
