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.
