Adds a cubic Bézier spline to the path from the current
point to position p3 in user-space coordinates, using p1 and p2
as the control points. After this call the current point will be p3.
If there is no current point before the call to curveTo()
this function will behave as if preceded by a call to
moveTo(p1).
