The points parameter specifies an array of endpoints and control points of the connected curves. The first curve is constructed from the first point to the fourth point in the points array by using the second and third points as control points. In addition to the endpoint of the previous curve, each subsequent curve in the sequence needs exactly three more points: the next two points in the sequence are control points, and the third is the endpoint for the added curve. If there are previous lines or curves in the figure, a line is added to connect the endpoint of the previous segment to the starting point of the first cubic curve in the sequence.
