* The public (ok, semi-public) service for the status bar.
* <p>
* This interesting thing to note about this class is that most of the methods that
* are called from other classes just post a message, and everything else is batched
* and coalesced into a series of calls to methods that all start with "perform."
* There are two reasons for this. The first is that some of the methods (activate/deactivate)
* are on IStatusBarService, so they're called from the thread pool and they need to make their
* way onto the UI thread. The second is that the message queue is stopped while animations
* are happening in order to make for smoother transitions.
* <p>
* Each icon is either an icon or an icon and a notification. They're treated mostly
* separately throughout the code, although they both use the same key, which is assigned
* when they are created.
