  // The following flag is used to indicate whether the message's alignment
  // should be autodetected or inherited from Chrome UI. Callers should pass
  // the correct flag based on the origin of the message. If the message is
  // from a web page (such as the JavaScript alert message), its alignment and
  // directionality are based on the first character with strong directionality
  // in the message. Chrome UI strings are localized string and therefore they
  // should have the same alignment and directionality as those of the Chrome
  // UI. For example, in RTL locales, even though some strings might begin with
  // an English character, they should still be right aligned and be displayed
  // Right-To-Left.
  //
  // TODO(xji): If the message is from a web page, then the message
  // directionality should be determined based on the directionality of the web
  // page. Please refer to http://crbug.com/7166 for more information.
