-/* 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.
