45 CCRenderTexture is a generic rendering target. To render things into it,
46 simply construct a render target, call begin on it, call visit on any cocos
47 scenes or objects to render them, and call end. For convienience, render texture
48 adds a sprite as it's display child with the results, so you can simply add
49 the render texture to your scene and treat it like any other CocosNode.
50 There are also functions for saving the render texture to disk in PNG or JPG format.
