-/* Theory of Operation
- * -------------------
- *
- * 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.
