Original change's description:
> Chrome retrieves Browser Actions' custom item icons through resource ids
> 
> Browser Actions will pass only the resource ids of the custom items'
> icons through the Intent, instead of passing the whole Bitmaps. Then
> with the source package name, Chrome can retrieve the client app's
> Resources by PackageManager.getResourcesForApplication() and use it to
> get the icons.
