+ scenes or objects to render them, and call end. For convienience, render texture
+ adds a sprite as it's display child with the results, so you can simply add
+ the render texture to your scene and treat it like any other CocosNode.
+ There are also functions for saving the render texture to disk in PNG or JPG format.
