/**
* Aligns this Game Object within another Game Object, or Rectangle, known as the
* 'container', to one of 9 possible positions.
*
* The container must be a Game Object, or Phaser.Rectangle object. This can include properties
* such as `World.bounds` or `Camera.view`, for aligning Game Objects within the world
* and camera bounds. Or it can include other Sprites, Images, Text objects, BitmapText,
* TileSprites or Buttons.
*
* Please note that aligning a Sprite to another Game Object does **not** make it a child of
* the container. It simply modifies its position coordinates so it aligns with it.
*
* The position constants you can use are:
*
* `Phaser.TOP_LEFT`, `Phaser.TOP_CENTER`, `Phaser.TOP_RIGHT`, `Phaser.LEFT_CENTER`,
* `Phaser.CENTER`, `Phaser.RIGHT_CENTER`, `Phaser.BOTTOM_LEFT`,
* `Phaser.BOTTOM_CENTER` and `Phaser.BOTTOM_RIGHT`.
*
* The Game Objects are placed in such a way that their _bounds_ align with the
* container, taking into consideration rotation, scale and the anchor property.
* This allows you to neatly align Game Objects, irrespective of their position value.
*
* The optional `offsetX` and `offsetY` arguments allow you to apply extra spacing to the final
* aligned position of the Game Object. For example:
*
* `sprite.alignIn(background, Phaser.BOTTOM_RIGHT, -20, -20)`
*
* Would align the `sprite` to the bottom-right, but moved 20 pixels in from the corner.
* Think of the offsets as applying an adjustment to the containers bounds before the alignment takes place.
* So providing a negative offset will 'shrink' the container bounds by that amount, and providing a positive
* one expands it.
*
* @method
* @param {Phaser.Rectangle|Phaser.Sprite|Phaser.Image|Phaser.Text|Phaser.BitmapText|Phaser.Button|Phaser.Graphics|Phaser.TileSprite} container - The Game Object or Rectangle with which to align this Game Object to. Can also include properties such as `World.bounds` or `Camera.view`.
* @param {integer} [position] - The position constant. One of `Phaser.TOP_LEFT` (default), `Phaser.TOP_CENTER`, `Phaser.TOP_RIGHT`, `Phaser.LEFT_CENTER`, `Phaser.CENTER`, `Phaser.RIGHT_CENTER`, `Phaser.BOTTOM_LEFT`, `Phaser.BOTTOM_CENTER` or `Phaser.BOTTOM_RIGHT`.
* @param {integer} [offsetX=0] - A horizontal adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
* @param {integer} [offsetY=0] - A vertical adjustment of the Containers bounds, applied to the aligned position of the Game Object. Use a negative value to shrink the bounds, positive to increase it.
