- Refactor some basic scrim logic to Scrim class and have WorkspaceAndHotseatScrim and OverviewScrim extend it - Draw OverviewScrim under recents unless predictions are disabled, in which case draw it under hotseat (since that is in recents) - Remove sysui scrim (behind status bar and nav bar) when overview is peeking Bug: 132455160 Change-Id: Ia5d6f54582a4c5a70e3b2d4a98281567edd68519
