<!-- In-call onscreen touch UI elements, used on some platforms.

     This layout is a fullscreen overlay, drawn on top of the
     non-touch-sensitive parts of the in-call UI (i.e. the call card).

     The top-level View here is a FrameLayout with 2 children:
       (1) incomingCallWidget: the UI displayed while an incoming call is ringing
       (2) inCallControls: the widgets visible while a regular call (or calls) is in progress
     Exactly one of these is visible at any given moment.
