/**
* Phaser - http://www.phaser.io
*
* v1.0.1 - Built at: Wed, 18 Sep 2013 05:29:56 +0000
*
* @author Richard Davey http://www.photonstorm.com @photonstorm
*
* A feature-packed 2D HTML5 game framework born from the smouldering pits of Flixel and
* constructed via plenty of blood, sweat, tears and coffee by Richard Davey (@photonstorm).
*
* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com/ @Doormat23.
*
* Follow Phaser development progress at http://www.photonstorm.com
*
* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from both which Phaser
* and my love of game development originate.
*

A RenderTexture is a special texture that allows any pixi displayObject to be rendered to it.

Otherwise black rectangles will be drawn instead.
RenderTexture takes snapshot of DisplayObject passed to render method. If DisplayObject is passed to render method, position and rotation of it will be ignored. For example:
