/**
* The Phaser.Game object is the main controller for the entire Phaser game. It is responsible
* for handling the boot process, parsing the configuration values, creating the renderer,
* and setting-up all of the Phaser systems, such as physics, sound and input.
* Once that is complete it will start the default State, and then begin the main game loop.
*
* You can access lots of the Phaser systems via the properties on the `game` object. For
* example `game.renderer` is the Renderer, `game.sound` is the Sound Manager, and so on.
*
* Anywhere you can access the `game` property, you can access all of these core systems.
* For example a Sprite has a `game` property, allowing you to talk to the various parts
* of Phaser directly, without having to look after your own references.
*
* In it's most simplest form, a Phaser game can be created by providing the arguments
* to the constructor:
*
* ```
* var game = new Phaser.Game(800, 600, Phaser.AUTO, '', { preload: preload, create: create });
* ```
*
* In the example above it is passing in a State object directly. You can also use the State
* Manager to do this:
*
* ```
* var game = new Phaser.Game(800, 600, Phaser.AUTO);
* game.state.add('Boot', BasicGame.Boot);
* game.state.add('Preloader', BasicGame.Preloader);
* game.state.add('MainMenu', BasicGame.MainMenu);
* game.state.add('Game', BasicGame.Game);
* game.state.start('Boot');
*
* ```
* In the example above, 4 States are added to the State Manager, and Phaser is told to
* start running the `Boot` state when it has finished initializing. There are example
* project templates you can use in the Phaser GitHub repo, inside the `resources` folder.
*
* Instead of specifying arguments you can also pass a single object instead:
*
* ```
* var config = {
* width: 800,
* height: 600,
* renderer: Phaser.AUTO,
* antialias: true,
* multiTexture: true,
* state: {
* preload: preload,
* create: create,
* update: update
* }
* }
*
* var game = new Phaser.Game(config);
* ```
*
* @class Phaser.Game
* @constructor
* @param {number|string} [width=800] - The width of your game in game pixels. If given as a string the value must be between 0 and 100 and will be used as the percentage width of the parent container, or the browser window if no parent is given.
* @param {number|string} [height=600] - The height of your game in game pixels. If given as a string the value must be between 0 and 100 and will be used as the percentage height of the parent container, or the browser window if no parent is given.
* @param {number} [renderer=Phaser.AUTO] - Which renderer to use: Phaser.AUTO will auto-detect, Phaser.WEBGL, Phaser.WEBGL_MULTI, Phaser.CANVAS or Phaser.HEADLESS (no rendering at all).
* @param {string|HTMLElement} [parent=''] - The DOM element into which this games canvas will be injected. Either a DOM ID (string) or the element itself.
* @param {object} [state=null] - The default state object. A object consisting of Phaser.State functions (preload, create, update, render) or null.
* @param {boolean} [transparent=false] - Use a transparent canvas background or not.
* @param {boolean} [antialias=true] - Draw all image textures anti-aliased or not. The default is for smooth textures, but disable if your game features pixel art.
* @param {object} [physicsConfig=null] - A physics configuration object to pass to the Physics world on creation.
