Layout:
Use an absolute-fill view as the background with the sidebar on top of. This
greatly simplifies styling, as there is no need to calculate how large the
backdrop needs to be.
Animation:
Switch to a translateX transform animation. This serves 2 purposes: first,
there seems to be a bug somewhere in React Native 0.51-0.55 where the content
that is being animated starts to be clipped. Very weird! But more importantly,
translateX transmorm animations are supported by the native animation driver!
https://facebook.github.io/react-native/blog/2017/02/14/using-native-driver-for-animated.html8f5ebe5952/Libraries/Animated/src/NativeAnimatedHelper.js (L138-L176)
This makes the animation more performant and buttery smooth.
Some small cleanups are also included here.
TouchableWithoutFeedback and TouchableHighlight interfere with the
implementation of 'pinch to zoom' to come. We prepare for it by driving
the onClick/onPress handler(s) out of Conference, through LargeVideo and
ParticipantView into Video itself where the bulk of 'pinch to zoom' will
be implemented.
In preparation for "pinch to zoom" support in desktop streams on mobile, make
certain Views not intervene in touch event handling. While the modification is
necessary for "pinch to zoom" which is coming later, it really makes sense for
the modified Views to not be involved in touching because they're used to aid
layout and/or animations and are to behave to the user as if they're not there.
Whatever I've tried so far ends up failing in really weird ways, so let's admit
defeat, for now. Destroy containers only on Android.
This shall be revisited when we update RN to version >= 0.43 and we have
"display: 'none'" available.
When a Container is not visible there is no need for it to react to touch
events, thus avoid wrapping it in a touch component.
In addition, simplify the style needed for hiding the component. Moving the view
out of the window boundaries no longer works on RN 0.42 on iOS. Seting the size
to 0 works well on both platforms, but in the future (when we upgrade to RN >=
0.43) we should switch to display: none:

This essentially reverts

In the filmstrip we keep a container full of thumbnail views. Destroying these
every time we want we want to hide it is costly, as new renderers have to be
recreated, and they lack context, so there is an increased chance for "black
thumbnails".
Introduce certain React Components which may be used to write
cross-platform source code such as Audio like Web's audio, Container
like Web's div, Text like Web's p, etc.
