- Next secondary icon animates up to replace dismissed main notification
- Add padding around main notification so it always aligns with the
straight edges of the view (not the rounded corners); looks more
dismissable
- Notification view collapses as notifications are dismissed
- To mimic system notification behavior, we copy SwipeHelper,
FlingAnimationUtils, and Interpolators. We also apply elevation
to notifications and reveal a darker color beneath when dismissing.
