Lock/login design updates
- How to show urgent notifications? The current design just has notifications indicated with the app icon and a count. For something like a critical power notification, or an incoming call, we probably need something more prominent and descriptive.
- How to show a logo? We didn't feel that there was room to show a distributor logo, and decided to show the OS name and version in the top-left instead. However, it has subsequently become apparent that some internal deployments basically require that a logo be displayed, so we do need this capability.
- We need to be able to show a session menu on the lock screen, in case automatic unlock is enabled.
