/**
 * @classdesc
 * The Shine FX Controller.
 *
 * This FX controller manages the shift effect for a Game Object.
 *
 * The shine effect is a visual technique that simulates the appearance of reflective
 * or glossy surfaces by passing a light beam across a Game Object. This effect is used to
 * enhance visual appeal, emphasize certain features, and create a sense of depth or
 * material properties.
 *
 * A Shine effect is added to a Game Object via the FX component:
 *
 * ```js
 * const sprite = this.add.sprite();
 *
 * sprite.preFX.addShine();
 * sprite.postFX.addShine();
 * ```
 *
 * @class Shine
 * @extends Phaser.FX.Controller
 * @memberof Phaser.FX
 * @constructor
 * @since 3.60.0
 *
 * @param {Phaser.GameObjects.GameObject} gameObject - A reference to the Game Object that has this fx.
 * @param {number} [speed=0.5] - The speed of the Shine effect.
 * @param {number} [lineWidth=0.5] - The line width of the Shine effect.
 * @param {number} [gradient=3] - The gradient of the Shine effect.
 * @param {boolean} [reveal=false] - Does this Shine effect reveal or get added to its target?
