Fixed here and elsewhere.

+var DecodeJPEG = chrome_private.DecodeJPEG;
 
-GetChromeHidden().registerCustomHook('chromePrivate', function(bindingsAPI) {
+var chromeHidden = requireNative('chrome_hidden').GetChromeHidden();
+
+chromeHidden.registerCustomHook('chromePrivate', function(bindingsAPI) {
   var apiFunctions = bindingsAPI.apiFunctions;
 
   apiFunctions.setHandleRequest(
       "chromePrivate.decodeJPEG", function(jpeg_image) {
     return DecodeJPEG(jpeg_image);
   });
 });
 
 })();
