fails on this line:
            if (px == nx) {
                // We might have two nodes with same x value for a short time
                if (point.equals(node.prev.point)) {
because node.prev is null

following fixes it in my as3 port:
            if (px == nx) {
                // We might have two nodes with same x value for a short time
                if (node.prev && point.equals(node.prev.point)) {
                    node = node.prev;
                } else if (node.next && point.equals(node.next.point)) {
                    node = node.next;
                } else if (point.equals(node.point)) {
