 // A window controller that handles the preferences window. The bulk of the
 // work is handled via Cocoa Bindings and getter/setter methods that wrap
 // cross-platform PrefMember objects. When prefs change in the back-end
 // (that is, outside of this UI), our observer receives a notification and can
 // tickle the KVO to update the UI so we are always in sync. The bindings are
 // specified in the nib file. Preferences are persisted into the back-end
 // as they are changed in the UI, and are thus immediately available even while
 // the window is still open. When the window closes, a notification is sent
 // via the system NotificationCenter. This can be used as a signal to
 // release this controller, as it's likely the client wants to enforce there
 // only being one (we don't do that internally as it makes it very difficult
 // to unit test).
