    // All Sprites added to a SpriteBatchNode are drawn in one OpenGL ES draw call
    // If the Sprites are not added to a SpriteBatchNode then an OpenGL ES draw call will be needed for each one, which is less efficient
    //
    // When you animate a sprite, Animation changes the frame of the sprite using setDisplayFrame: (this is why the animation must be in the same texture)
    // When setDisplayFrame: is used in the Animation it changes the frame to one specified by the SpriteFrames that were added to the animation,
    // but texture id is still the same and so the sprite is still a child of the SpriteBatchNode, 
    // and therefore all the animation sprites are also drawn as part of the SpriteBatchNode
