<!-- 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.

            Layout notes:
            - Use an opaque black background since we need to cover up
              a bit of the bottom of the contact photo
            - The verticalOffset value gets us a little extra space above
              the topmost "Respond by SMS" icon
            - The negative layout_marginBottom shifts us slightly downward;
              we're already aligned with the bottom of the screen, but we
              don't have an icon in the downward direction so the whole
              bottom area of this widget is just wasted space.
