Meta question: should we have a MessageCenterNotificationBridge instead? What's
the benefit of forking on the level of the DisplayManager?

[Peter Beverloo, 2016/04/18 14:57:09]

Could we call this MessageCenter(Notification)DisplayService, consistent with
the other message_center_* files in this directory?

Discussed offline, I found myself converting back and forth from Profile* to
profile_id. While NotificationUIManager exists we need to fork at this level.

OK, it seemed more descriptive this way, went with MessageCenterDisplayService
sine the other one seemed too long.

+// instead of the native platform notification center.

nit:

// NotificationDisplayService implementation.

[Miguel Garcia, 2016/04/19 14:24:57]

Done.
