Two changes for the latest Compose prototype: 1. Pass the identity of the underlying app to the Overscroll plugin. 2. Enable the Compose gesture over an app when there's a Recents extra card plugin active (otherwise the current app won't count as the rightmost one). Some changes to the gesture: - Angle decreased from 35° to 25° to remove overlap with Assistant gesture - Distance increased from 8 to 110 dp. 110 dp is 2x the Assistant gesture and roughly the same as scrubbing into an app from Home. - Fling detection added; uses same distance threshold, 110 dp. - If a touch was recognized as another gesture, the touch will not be reinterpreted as a Compose gesture, no matter what touch movement occurs - Fixes issue where Assistant + Compose could both be triggered - Fixes issue where scrubbing apps to the left, then back to the right, would bring in Compose. i.e. if a touch down + touch movement starts bringing in Assistant UI elements, then, the user moves their touch below the Assistant angle, the Compose gesture will not start being recognized - Gesture length required for fling lowered from 110 dp to 40 dp, per tuning with PM.
