Extend the current subpath with a cubic Bezier curve.
The curve will go from the current end point (or the first
control point if the current path is empty) to the given
point, which will become the new end point. The curve will be
tangent toward the first control point at the beginning and
tangent toward the second control point at the end. The
current transform at the time that this is called will affect
all points passed in.
Tip: to make multiple curves join smoothly, ensure that each
new end point is on a line between the adjacent control
points.
