/**
 * @classdesc
 * The Input Plugin belongs to a Scene and handles all input related events and operations for it.
 *
 * You can access it from within a Scene using `this.input`.
 *
 * It emits events directly. For example, you can do:
 *
 * ```javascript
 * this.input.on('pointerdown', callback, context);
 * ```
 *
 * To listen for a pointer down event anywhere on the game canvas.
 *
 * Game Objects can be enabled for input by calling their `setInteractive` method. After which they
 * will directly emit input events:
 *
 * ```javascript
 * var sprite = this.add.sprite(x, y, texture);
 * sprite.setInteractive();
 * sprite.on('pointerdown', callback, context);
 * ```
 *
 * Please see the Input examples and tutorials for more information.
 *
 * @class InputPlugin
 * @extends Phaser.Events.EventEmitter
 * @memberOf Phaser.Input
 * @constructor
 * @since 3.0.0
 *
 * @param {Phaser.Scene} scene - A reference to the Scene that this Input Plugin is responsible for.
