 * Adds a spline curve segment to a custom shape.`splineVertex()` adds a curved segment to custom shapes. The spline curves
 * it creates are defined like those made by the
 * curve() function. `splineVertex()` must be called
 * between the beginShape() and
 * endShape() functions.Spline curves can form shapes and curves that slope gently. They’re like
 * cables that are attached to a set of points. Splines are defined by two
 * anchor points and two control points. `splineVertex()` must be called at
 * least four times between
 * beginShape() and
 * endShape() in order to draw a curve:`beginShape();
 * 
 * // Add the first control point.
 * splineVertex(84, 91);
 * 
 * // Add the anchor points to draw between.
 * splineVertex(68, 19);
 * splineVertex(21, 17);
 * 
 * // Add the second control point.
 * splineVertex(32, 91);
 * 
 * endShape();`The code snippet above would only draw the curve between the anchor points,
 * similar to the curve() function. The segments
 * between the control and anchor points can be drawn by calling
 * `splineVertex()` with the coordinates of the control points:`beginShape();
 * 
 * // Add the first control point and draw a segment to it.
 * splineVertex(84, 91);
 * splineVertex(84, 91);
 * 
 * // Add the anchor points to draw between.
 * splineVertex(68, 19);
 * splineVertex(21, 17);
 * 
 * // Add the second control point.
 * splineVertex(32, 91);
 * 
 * // Uncomment the next line to draw the segment to the second control point.
 * // splineVertex(32, 91);
 * 
 * endShape();`The first two parameters, `x` and `y`, set the vertex’s location. For
 * example, calling `splineVertex(10, 10)` adds a point to the curve at
 * `(10, 10)`.Spline curves can also be drawn in 3D using WebGL mode. The 3D version of
 * `splineVertex()` has three arguments because each point has x-, y-, and
 * z-coordinates. By default, the vertex’s z-coordinate is set to 0.Note: `splineVertex()` won’t work when an argument is passed to
 * beginShape().
