Alessandro Ranellucci	bf02062a67	Bugfix: random but frequent crashes after recent perimeter code refactoring	2015-01-14 22:55:11 +01:00
Alessandro Ranellucci	406d045ced	The inwards move after an external loop was still randomly generated outwards in some cases. Perimeters are now generated with a distinct iterator for each slice. Nested islands are also correctly supported too. Various regression tests included. #2253	2015-01-08 15:22:13 +01:00
