To support this feature, the input dispatcher now allows input events to be acknowledged out-of-order. As a result, the consumer can choose to defer handling an input event from one device (because it is building a big batch) while continuing to handle input events from other devices. The InputEventReceiver now sends a notification when a batch is pending. The ViewRoot handles this notification by scheduling a draw on the next sync. When the draw happens, the InputEventReceiver is instructed to consume all pending batched input events, the input event queue is fully processed (as much as possible), and then the ViewRoot performs traversals as usual. With these changes in place, the input dispatch latency is consistently less than one frame as long as the application itself isn't stalled. Input events are delivered to the application as soon as possible and are handled as soon as possible. In practice, it is no longer possible for an application to build up a huge backlog of touch events. This is part of a series of changes to improve input system pipelining.
