This describes the transform that a compositor will apply to a

The flipped values correspond to an initial flip around a
vertical axis followed by rotation.
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.
