Swipe to unlock - Fix alpha continuity
Many transitions should start from the last value used in the UI
layer, such as alpha, translationX, translationY. In the case of swipe
to unlock, as the user is swiping up, elements are fading out until a
certain point is reached which then triggers a LOCKSCREEN->GONE
transition. This transition should begin from the current alpha value
rather than some other arbitrary point.
