Core wayland protocol
- We need rotation information in the output (multiples of 90
degrees) and we'll need a way for a client to communicate that it
has rendered its buffer according to the output rotation. The
goal is to be able to pageflip directly to the client buffer, and
for that we need the client to render accordingly and the
compositor needs to know that it did.
- Atomicity. Currently a lot of the atomicity in Wayland relies on
how we batch up all requests in a protocol buffer and only flushes
in the "blockhandler" in the client. Consensus was that we need

This describes the transform that a compositor will apply to a
surface to compensate for the rotation or mirroring of an
output device.
The flipped values correspond to an initial flip around a
vertical axis followed by rotaion.
The purpose is mainly to allow clients render accordingly and
tell the compositor, so that for fullscreen surfaces, the
compositor will still be able to scan out directly from client
surfaces.
