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