Scale down thumbnail with app surface
The recents Go app to overview transition has app scale down to a thumbnail but normally covers the thumbnail. However, apps with transparency will be semi-visible and will allow the user to see the thumbnail in the back at its final size. Instead, we should fit the thumbnail to the surface so that they both scale down at the same time. Bug: 132458092 Test: Go to app with transparency, scale down Change-Id: Iaebeaaf2ddcfc86fd4f55ef9d8c3f19583947c48
