++ * 1. Clients render to their pixmaps and Windows aggregating damage.
++ * 2. Before blocking, we walk the list of dirty Windows and submit
++ * any damage to Mir. This consumes the xfer buffer.
++ * 3. Clients continue to render and we accumulate damage. However,
++ * as there is now no xfer buffer free, damage accumulates.
++ * 4. Mir reports that its exchange has complete and gives us a new
++ * transport buffer.
++ * 5. Before going to sleep, we iterate over dirty Windows and copy
++ * their damage into the xfer buffer and send back to Mir.
++ *
++ * Clients render uninterrupted, but we only send damage to Mir once
++ * every frame.
