Adds an instance of {@link QuadraticBezierCurve} to the path by connecting
the current point with the given one.

@param {number} aCPx - The x coordinate of the control point.
@param {number} aCPy - The y coordinate of the control point.
@param {number} aX - The x coordinate of the end point.
@param {number} aY - The y coordinate of the end point.
@return {Path} A reference to this path.
