Broken for certain sets of points

Example:
[(0.51, 0.31), (0.41, 0.71), (0.61, 0.71), (0.11000000000000001, 0.21000000000000002), (0.11000000000000001, 0.61), (0.71, 0.71), (0.31, 0.61), (0.21000000000000002, 0.01), (0.41, 0.31), (0.51, 0.01)]

Hi, I found out that this bug happens when you have two points on plane with the same y coord. Then there are NaN values when searching for parabolas intersections at: getXofEdge. Unfortunately I wasnt able to fix that, but there is workaround for that - just generate random vertices with double y coord or if you dont care about some of the vertices, just delete duplicated y coordinates. This may help ;)

		ArrayList<Point> points = new ArrayList<Point>();
		Set<Point> set = new LinkedHashSet();
		set.addAll(points);
		points.clear();
		points.addAll(set);
