*@brief A 9-slice sprite for cocos2d-x.
*
* 9-slice scaling allows you to specify how scaling is applied
* to specific areas of a sprite. With 9-slice scaling (3x3 grid),
* you can ensure that the sprite does not become distorted when
* scaled.
* Note: When you set _scale9Enabled to false,
* then you could call `scale9Sprite->getSprite()` to return the inner Sprite pointer.
* Then you could call any methods of Sprite class with the return pointers.
