The animation from Overview to OverviewSplitSelect is now updated to the latest spec. See bug for details. - New timings - Task thumbnails slide in with a new spring animation - Icons fade out and fade in appropriately - SplitInstructionsView has a new compound "unfold" animation Bug: 236760307 Test: Manual on tablet and phone. Looks good on both true and fake orientations. Change-Id: If98d4464aa51c876d79bee9672279992a2cf9026
