32/** CCAtlasNode is a subclass of CCNode that implements the CCRGBAProtocol and
33 CCTextureProtocol protocol
34
35 It knows how to render a TextureAtlas object.
36 If you are going to render a TextureAtlas consider subclassing CCAtlasNode (or a subclass of CCAtlasNode)
37
38 All features from CCNode are valid, plus the following features:
39 - opacity and RGB colors
