 // Displays onscreen animations and locks or suspends the system in response to
 // the power button being pressed or released.
 // Lock workflow:
 // Entry points:
 //  * StartLockAnimation (bool shutdown after lock) - starts lock that can be
 //    cancelled.
 //  * StartLockAnimationAndLockImmediately - starts uninterruptible lock
 //    animation.
 // This leads to call of either StartImmediatePreLockAnimation or
 // StartCancellablePreLockAnimation. Once they complete
 // PreLockAnimationFinished is called, and system lock is requested.
 // Once system locks and lock UI is created, OnLockStateChanged is called, and
 // StartPostLockAnimation is called. In PostLockAnimationFinished two
 // things happen : EVENT_LOCK_ANIMATION_FINISHED notification is sent (it
 // triggers third part of animation within lock UI), and check for continuing to
 // shutdown is made.
 //
 // Unlock workflow:
 // WebUI does first part of animation, and calls OnLockScreenHide(callback) that
 // triggers StartUnlockAnimationBeforeUIDestroyed(callback). Once callback is
 // called at the end of the animation, lock UI is deleted, system unlocks, and
 // OnLockStateChanged is called. It leads to
 // StartUnlockAnimationAfterUIDestroyed.
