title: Load TTF font from external path
body: <p>I was wondering that how to load a TTF font from a absolute file path, not relative, which is usually done with
  [UIFont fontWithName:@"xyz"];</p>
  
  <p>In cocos2d we can do it by using CCLabelBMFont that takes file as parameter, but when use CCLabelTTF it takes the name of font, not the file name.</p>
  
  <p>Is there any workaround to load an external font not embedded with the application but downloaded from some resource as per need ?</p>
