* usually affects the animation aspects vertically, as the system decoration is

* @param surfaceInsets In rare situation the surface is larger than the content and we need to
* know about this to make the animation frames match. We currently use
* this for freeform windows, which have larger surfaces to display
* shadows. When we animate them from recents, we want to match the content
