The arguments are pairs of points. At least 4 pairs must be specified.
Each point xn, yn on the curve is associated with a control point
cxn, cyn. The first point, x1, y1, is the starting point. The last
point, xn, yn, is the ending point. Other point/control point pairs
specify intermediate points on a polybezier curve.
Draw a cubic Bezier curve.
