This commit adds protocol additions making it possible to request that a
popup should be repositioned according to a new xdg_positioner object.
Explicit popup moving is done using a new request on xdg_popup:
xdg_popup.reposition. What it does is change the parameters used for
positioning a popup by providing a new xdg_positioner object. This
request is coupled with a new event; xdg_popup.repositioned, sent
together with the configure events (xdg_popup.configure and
xdg_surface.configure) to notify about the completion of the reposition
request. The reposition request also takes a token that is later passed
via the repositioned event; this is done so that a client may determine
for which reposition request the compositor has sent configure events.
Synchronization between surfaces to avoid state application race
condition are deliberately left out, and should be handled by an
external protocol.
To brief the compositor of the future dimension of the parent that the
compositor should position the popup against, a
xdg_positioner.set_parent_size request is added.
Lastly, a request to couple a xdg_positioner object with a parent
configure event is added (xdg_positioner.set_parent_configure) in
order for a compositor to pair a popup reposition request with a pending
configure event, and it's resulting window geometry. This is necessary
to, for example, properly constrain a popup given a future parent state.
An example of when this may be necessary is an interactive resize where
both the toplevel position and the relative popup position changes.

This commit adds protocol additions making it possible to implicitly
reposition an already mapped popup if the conditions for the constraint
changed (e.g. toplevel moved).
Implicit popup moving is done by setting a adjustment flag on the
positioner used to create it that will cause the compositor to adjust
the position as the conditions used to constrain it change.
These changes may include, for example, changes in the position of the
parent window or the geometry of the work area. To allow the client to
update its content in response to the updated position, the client must
ack the configure event, optionally with new content. Until the client
acks this configure event, the existing positioner will continue to be
used.
Implicit repositioning by itself is racy regarding inter-surface
synchronization of applied state. Inter-surface synchronization is
deliberately left out of xdg-shell, and left to be handled externally.

The output description is a human-readable text describing the output. Unlike
the name which uniquely identifies the output, it's intended to be displayed to
the user.
It might be desirable for a compositor to update an output's description. For
instance, when only one output is plugged in, it's not necessary to dump make,
model, serial and connector to the description, something like "Dell U2717D" is
enough. However when two identical outputs are plugged in it's necessary to add
e.g. the connector type to tell them apart ("Dell U2717D on HDMI"). See [1] for
a discussion about this.
This commit bumps xdg_output's version to allow compositors to update the
property.

LibreOffice is one big binary with explicit brandings for different
application modules. This is represented in X11 by a different
WM_CLASS setting for a window. The WM_CLASS is changed based on the
loaded document at runtime. As a result LibreOffice already offers
multiple desktop files with different icons, StartupWMClass
entries and application names.
This amendment of the set_app_id request just explicitly specifies
the use case to change a surfaces' app ID at runtime, so a compositor
implementor is made aware of it. Just as the WM_CLASS, a change of
the app ID should result in an update of the propertes of a surface
depending on the app ID, like the window icon specified in the
desktop file or a re-grouping of the surfaces in a task manager.

This commit makes it so a wl_output.done event is guaranteed to be sent with a
xdg_output.done event.
This protocol change has been discussed in a recent xorg-devel discussions [1].
First let's recap why a change is needed: Xwayland listens to both wl_output and
xdg_output changes. When an output's properties change, Xwayland expects to
receive both a wl_output.done event and an xdg_output.done event. If that's not
the case, Xwayland doesn't update its state (so old state is still exposed to
X11 clients).
Most of the time, both objects will be updated at the same time (e.g. the
current mode is changed, so both wl_output.mode and xdg_output.logical_size are
sent) so this won't be an issue. However in some situations only one of
wl_output or xdg_output changes. For instance:
- The mode is changed at the same time as the scale, resulting in the same
logical_size.
- The compositor doesn't expose the outputs' position via wl_output, so whenever
the position changes only xdg_output is updated.
Both KDE [2] and wlroots [3] have experienced this issue.
For this reason, I'd like to update the xdg-output protocol to make it mandatory
to always send a wl_output.done event after xdg_output changes. This effectively
makes wl_output.done atomically apply all output state (including the state of
add-on objects like xdg_output). This approach is pretty similar to
wl_surface.commit: this request will atomically apply surface state including
the state of e.g. the xdg_surface object tied to the wl_surface.
To update the protocol to reflect this new requirement we can either:
- **Bump xdg_output version**. The current protocol doesn't specify that
wl_output.done must be sent, adding this new requirement would be a breaking
change. We need to fix Xwayland for the current xdg_output version (maybe make
it non-atomic for the current version, atomic for the new one?). Should we
deprecate xdg_output.done in the new version?
- **Don't bump xdg_output version**. This clarifies what is expected in practice
by Xwayland, a major xdg_output consumer, and what is currently implemented by
all compositors.
There's one issue with the "don't bump" approach: indeed in practice compositors
always send wl_output.done and xdg_output.done in pairs, however the ordering
between those two events is not guaranteed. This means some compositors might
send this sequence:
wl_output.geometry(…)
wl_output.done()
xdg_output.logical_position(…)
xdg_output.done()
In this case the wl_output.done event fails to atomically apply the xdg_output
state.
For this reason, I think bumping the version is a better approach.
This commit also deprecates xdg_output.done, which doesn't have any purpose
anymore.

Also make it clearer that implementations are free to support other
buffer types beyond the required ones.

This protocol enables explicit synchronization of asynchronous graphics
operations on buffers on a per-commit basis. Support is currently
limited to dmabuf buffers and dma_fence fence FDs.
Explicit synchronization provides a more versatile notification
mechanism for buffer readiness and availability, and can be used to
improve efficiency by integrating with related functionality in display
and graphics APIs.
This protocol is also useful in ChromeOS ARC++ (running Android apps
inside ChromeOS, using Wayland as the communication protocol), where it
can enable integration of the ChromeOS compositor with the explicit
synchronization mechanisms of the Android display subsystem.
Finally, the per-commit nature of the release events provided by this
protocol potentially offers a solution to a deficiency of the
wl_buffer.release event (see
https://gitlab.freedesktop.org/wayland/wayland/issues/46).

The wording in xdg-shell's `set_*` requests implies the compositor
*will* honour the client's request.
This would give clients the control over their actual state, while the
general expectation is that clients kindly ask for state changes which

This patch ensures the actual protocol text reflects these expectations.

This adds two events to the protocol. The goal is to allow clients to
give the user the ability to select outputs with the same names the
compositor uses and to identify outputs consistently across sessions.
The output name is a short and stiff identifier with strict limits on
permitted characters, which is suitable for storing in config files,
command line arguments, etc. A warmer "description" event is also
provided to (optionally) provide a more human readable name, and has
much broader restrictions on its form.

wl_pointer, wl_keyboard and wl_touch events currently use a 32-bit
timestamp with millisecond resolution. In some cases, notably latency
measurements, this resolution is too coarse to be useful.
This protocol provides additional high-resolution timestamps events,
which are emitted before the corresponding input event. Each timestamp
event contains a high-resolution, and ideally higher-accuracy, version
of the 'time' argument of the first subsequent supported input event.
Clients that care about high-resolution timestamps just need to keep
track of the last timestamp event they receive and associate it with the
next supported input event that arrives.
