problem with S2loop::init about s2geometry HOT 2 OPEN

So edges 1 and 3 would be edges:

(-1.0780759735047707, 1.4666611693199976)-(-0.981471670584179, -3.0839249353037306) and 
(-0.9814705651439662, -3.081737300942303)-(-1.0780749761978428, 1.4688488034282494) 

which don't cross when I test them manually.

Can you print the individual S2Points that form the polygon with
fprintf(stderr, "%.18e %.18e %.18e\n", pnt.x(), pnt.y(), pnt.z());?
That'll give me full precision on the actual points in the polygon so I can
check them.

@catmagic Alternatively, can you add a test case to s2loop_test.cc that demonstrates the problem? Having runnable code will make this easier to debug.
