-// DOM-based login UI implementation.
-// This class is a Singleton. It allows the LoginDisplayHost and LoginUIHandler
-// to access it without having to be coupled with each other. It is created with
-// NULL for the delegate and a 0-size rectangle for the background
-// bounds. Before use these values should be set to a sane value. When done with
-// the object, the ExistingUserController should call Destroy and not free the
-// pointer, where as accessing classes should do nothing with the pointer.
-//
-// Expected order of commands to setup for LoginDisplayHost:
-//   DOMLoginDisplay::GetInstance();
-//   set_delegate(delegate);
-//   set_background_bounds(background_bounds());
-//   Init();
-//
-// Expected order of commands to setup for LoginUIHandler:
-//   DOMLoginDisplay::GetInstance();
-//   set_login_handler(this);
