* <p>cc.LabelBMFont is a subclass of cc.SpriteBatchNode.</p>
*
* <p>Features:<br/>
* <ul><li>- Treats each character like a cc.Sprite. This means that each individual character can be:</li>
* <li>- rotated</li>
* <li>- scaled</li>
* <li>- translated</li>
* <li>- tinted</li>
* <li>- chage the opacity</li>
* <li>- It can be used as part of a menu item.</li>
* <li>- anchorPoint can be used to align the "label"</li>
* <li>- Supports AngelCode text format</li></ul></p>
*
* <p>Limitations:<br/>
* - All inner characters are using an anchorPoint of (0.5, 0.5) and it is not recommend to change it
* because it might affect the rendering</p>
*
* <p>cc.LabelBMFont implements the protocol cc.LabelProtocol, like cc.Label and cc.LabelAtlas.<br/>
* cc.LabelBMFont has the flexibility of cc.Label, the speed of cc.LabelAtlas and all the features of cc.Sprite.<br/>
* If in doubt, use cc.LabelBMFont instead of cc.LabelAtlas / cc.Label.</p>
