Note that with this workflow you need two click-hold-release sequences to create a single Bezier curve of third degree.
 * The first click-hold defines the first end point.
 * The first release defines the first control point.
 * The second click-hold defines the second end point, and the general direction of the spline.
 * The second release defines the final curvature of the spline.
 * The second control point is not explicitly given, but is determined from the location of the pointer during the second release.
