Multiple Batched Texture support is now available. This is a WebGL feature that can seriously decrease the volume of draw calls made in complex, or asset heavy, games. To enable it you can either use the new renderer type Phaser.WEBGL_MULTI, or you can pass the property multiTexture: true in a Phaser.Game configuration object. Once enabled, it cannot be disabled.

`game.renderer.setTexturePriority` is the method that goes with the Multiple Texture support. It takes an array as its single argument. The array consists of Phaser.Cache image key strings. Phaser will then try to batch as many of the textures as it can, depending on the hardware limits. If for example the GPU can only batch 8 textures, and you provide an array of 16, then only the first 8 in the array will be batched.

 * Weapon.multiFire is a new property that allows you to set a Weapon as being allowed to call `fire` as many times as you like, per game loop. This allows a single Weapon instance to fire multiple bullets.
 * Weapon.fire has two new arguments: `offsetX` and `offsetY`. If the bullet is fired from a tracked Sprite or Pointer, or the `from` argument is set, this applies a horizontal and vertical offset from the launch position.
 * Weapon.fireOffset attempts to fire a single Bullet from a tracked Sprite or Pointer, but applies an offset to the position first. This is a shorter form of calling `Weapon.fire` and passing in the offset arguments.

 * TypeScript definitions fixes and updates (thanks @chriteixeira @StealthC @Lopdo)
 * Docs typo fixes (thanks @JTronLabs @samme)
 * `Phaser.Line.fromSprite` now uses the Sprite.centerX and centerY properties if the `useCenter` argument is true. Before it required you to have overridden the Sprite and added the property yourself (thanks @samme #2729)

+* Updated the pointer check code in the Device class, to get rid of the message `Navigator.pointerEnabled is a non-standard API added for experiments only. It will be removed in near future.` in Chrome.

 /**
-* This is where the magic happens. The Game object is the heart of your game,
-* providing quick access to common functions and handling the boot process.
+* 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');
 * 
-* "Hell, there are no rules here - we're trying to accomplish something."
-*                                                       Thomas A. Edison
+* ```
+* 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
+*     }
+* }
