sky@, could I get a stamp from you for adding ui/aura as "ui/arc"'s deps?
Thanks.

Quick background:
For arc custom notifications, there are dynamically growing ones. This CL makes
ArcCustomNotificationView a aura::WindowObserver to observe the bounds change of
the aura::Window backing notification surface.

LGTM
