Use cubic Bézier spline. Has to be a sorted list of points in the format 'handle1x;handle1y#pointx;pointy#handle2x;handle2y'(pointx = in, pointy = out). Points are separated by a '|'.The values can have 'double' precision. x, y for points should be in the range 0-1. x,y for handles might also be out of this range.
