 // ChromeLauncherControllerPerBrowser manages the launcher items needed for

 // * Tabbed browsers and browser app windows have BrowserLauncherItemController,
 //   owned by the BrowserView instance.
 // * App shell windows have ShellWindowLauncherItemController, owned by
 //   ShellWindowLauncherController.
 // * Shortcuts have no LauncherItemController.
