From 47e8844564675cbc0e3f319371cc5252ccbbb870 Mon Sep 17 00:00:00 2001

Subject: Simplify and optimize InCall animation

* Remove the scrim and directly animate the call card container

* ResizeAnimation is no longer needed, instead we animate the height
of the card by using an ObjectAnimator and prevent any layout changes
from happening during the duration of that animation

* Change together Animators to remove some boilerplate

* Remove now redundant outer FrameLayout in call_card.xml
