 <!-- 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 InCallTouchUi (FrameLayout) with 2 children:
        (1) inCallControls: the widgets visible while a regular call (or calls) is in progress
        (2) incomingCallWidget: the UI displayed while an incoming call is ringing
      In usual cases, one of these is visible at any given moment.
      One exception is when incomingCallWidget is fading-out. At that moment, we show
      inCallControls beneath incomingCallWidget for smoother transition.
