#126 One more intersection issue with open paths

[Alessandro Ranellucci]

Hello Angus,
thank you very much for the recent fixes.

I updated to your last 6.2.8 version and those issues look fixed. However, there's one more issue with intersection that was also happening in 6.2.1.

SUBJECT OPEN PATH:
LINESTRING((200000 19799999,200000 200000,24304692 200000,15102879 17506106,13883200 19799999,200000 19799999))

CLIP CLOSED PATH:
POLYGON((15257205 18493894,14350057 20200000,-200000 20200000,-200000 -200000,25196917 -200000))

The subject path is entirely contained in the clipping polygon, but the result has a couple points reversed as you can see in the screenshot (black = subject, grey = clip, red = result).
