 // (1) Invoke the factory method, e.g.,
 //     PnaclCoordinator* coord = BitcodeToNative(plugin,
 //                                               "http://foo.com/my.pexe",

 //                                               translate_notify_callback);
 // (2) translate_notify_callback gets invoked when translation is complete.
 //     If the translation was successful, the pp_error argument is PP_OK.
