<!-- 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.

But note there are a couple of *pairs* of buttons that share a
single "slot", namely Hold/Swap and Add/Merge. For these, the
code in InCallTouchUi is responsible for making sure that at any
point exactly one of the pair is VISIBLE and the other is
GONE. -->
