#3357: Polygon intersection with line fails for geography

Comment (by pramsey):
Your line isn't straight like in your picture, it's actually straight in a
different way, as a great circle arc (which, in your picture would be a
northerly curve). Think about how an airplane would get between the ends
of your line. Reasoning about geography on flat maps leads to mistakes
like this.
