Removes the loops from a lineString (Test to outline a lineString without having weird overlaps) Please note that this algorithm is not optimized for performance. I recommend only using it in command line tools

// http://www.vitutor.com/geometry/distance/line_plane.html
var direction = -vector.z / Math.abs(vector.z); // Because vector angle is always shortest and has no direction
