Visibility bug corner case?

[azrafe7]

This polygon is not correctly decomposed by SnoeyinkKeil (it's a particular of big.png test image):

decomp:

poly points:

poly = [32,3, 18,9, 16,9, 17,6, 14,8, 9,4, 9,9, 0,12, 0,15, 12,12, 10,21, 20,15, 29,17, 21,12, 21,10, 32,7, 32,4 /*, 32,3*/];

It could also affect Bayazit, since now it's using Visibility.

Works fine with the original java implementation from Snoeyink it seems, so the problem must be on my side.

Note to self: check popVisible().
