If present, use the cursor-shape protocol instead of manually
updating a pointer surface. This commit supports both v1 of the
protocol and the (still unmerged) v2 additions to the enumeration.
This was tested with both kwin and mutter.

Some of the listeners connected during the initial roundtrip assume a
non-NULL selection, when they finally invoke functions such as
gdk_wayland_selection_ensure_offer(),
gdk_wayland_selection_ensure_primary_offer() or
gdk_wayland_selection_set_offer(). The GdkWaylandSelection should
therefore be initialized before the second series of roundtrips, as the
compositor may have already sent a selection by then.
This fixes potential runtime crashes in some somewhat unlikely
configurations, like a modern compositor but gtk built against an old
wayland protocols version.
We only need v2 for the tiling fixes, so request that.
The cursor-theme-size setting is documented as
'0 means the default size'. Make it so by using
size 24 if we see a 0. Its better than crashing.

This way we can keep the same wayland-protocols requirement, so the latest GTK3
still builds on distributions shipping older versions of wayland-protocols,
such as Debian Bullseye.
Should fix CI builds as well.
When using xdg_activation we need to keep the id around until we send
the first activate to signal succesful startup.

This adds a private GDK API that GTK calls using GDK_PRIVATE_CALL(). It
is more or less a copy of the GdkSurface::titlebar_gesture() API, and
achieves the same. If the backend or compositor doesn't support titlebar
gestures, the existing path is used as a fallback.
Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
... until all globals have been received.
The dependency tracking introduced in 4e9be39518 only allows to
specify required globals and processes the closures as soon as
the requirements have been met. There are, however, also optional
dependencies - most notably the primary_selection protocol.
Currently we rely on the fact that compositors like Mutter announce
it before `wl_seat`, even though the order is not specified in
the spec.
Process globals closures only after all globals have been announced,
so optional dependencies can be accommodated.
Closes https://gitlab.gnome.org/GNOME/gtk/-/issues/3791
Additionally to gtk_primary_selection, the gtk-private predecessor,
support the upstream unstable protocol.
This allows the primary selection to work on Kwin and potentially
other compositors, as well as dropping the private version eventually.

When using the gdk_display_close(), the handle to the Wayland compositor was not released.
This could cause the consumption of all available handles, preventing other processes from accessing the display.
Fixing this by calling wl_display_disconnect() when releasing the GdkWaylandDisplay object.

This adds a "release" destructor for the gtk_surface1 interface which
signals to the server that a surface has been destroyed on the client
side, which the current "destroy" does not do.
Ideally the protocol would have specified a destroy request marked as
destructor to handle this automatically, however this is no longer
possible due to the destroy method being implicitly generated in the
absence of an explicit request in the protocol. Adding a destroy request
marked as destructor now would generate a new destroy method that
unconditionally would send the request to the server, which would break
clients running on servers not supporting that request.
xdg-output v3 marks xdg-output.done as deprecated and compositors are
not required to send that event anymore.
So if the xdg-output version is 3 or higher, simply set the initial
value `xdg_output_done` to TRUE so we don't wait/expect that event
from the compositor.
https://gitlab.gnome.org/GNOME/gtk/issues/2053
The xdg_output interface has a `name` property that reflects the output
name coming from the compositor.
This is the closest thing we can get to a connector name.
Fixes: #1961
Previously, the GDK backend for Wayland would deduce the logical size
of the monitors from the wl_output size and scale.
With the addition of fractional scaling which advertises a larger scale
value and then scale down the client surface, the computed logical size
of the monitors in GDK would be wrong and confuse applications which
insist on using the monitor size and position (like Firefox).
The xdg-output protocol aims at describing outputs in a way which is more
in line with the concept of an output on desktop oriented systems by
presenting the outputs using their logical size and position appropriately
transformed.
Add support for the optional xdg-output protocol so that the size and
position of the monitors as reported by GDK is correct even when using
fractional scaling.

Add private API to GDK to move these variables from the environment into
static scope. Also move the DESKTOP_STARTUP_ID validation here to reduce
code duplication.
Use constructors to read them as early as possible; however, do not
unset them until first requested. This avoids breaking gnome-shell and
gnome-settings-daemon, which want to use the DESKTOP_AUTOSTART_ID in
their own gnome-session clients.
Fixes https://gitlab.gnome.org/GNOME/gtk/issues/1761
The use of the startup ID is now twofold, we reply back with it to end any
corresponding startup notification, but we also use it on
gtk_surface1.request_focus to acknowledge that the activation might raise
the corresponding window.
We should preserve the startup ID for the second to work properly, so avoid
clearing it here. It is inconsequential if the underlying
gtk_shell1.set_startup_id request happens multiple times on no longer existing
startup IDs, so don't bother preventing that from happening.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1754
This uses the gtk_surface1.request_focus request added in gtk-shell v3,
the given startup ID may be used by the compositor in order to determine
when was the request started, and whether user input happened in between.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/624
This functionality is similar to Linux's memfd. It creates anonymous shared memory without touching the filesystem, which allows it to work in Capsicum capability mode (sandbox).
This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

The internal known_globals hashtable is used to carry accounting for
interfaces that depend on others (as ordering is not guaranteed), extend
its usage so it also keeps track of unimplemented interfaces (here at
least).
The API call will then use this to allow querying the globals offered by
the compositor, it will be useful to determine whether we can use
text-input protocols or should fallback to other IMs.
If the compositor prefers server-side decorations and the client doesn't
customize the title bar, we disable client-side decorations and let the
compositor know. Otherwise, we continue to use client-side decorations.

Now that GTK windows have the ability to properly handle
per-edge tiling constraints, this patch extends GTK's
internal Wayland protocol to have a proper enum with the
relevant edge data.
Once this approach is validated, we can think of upstreaming
this work as an official Wayland protocol extension.

This adds support for the shortcut inhibitor protocol in gdk/wayland
backend.
A shortcut inhibitor request is issued from the gdk wayland backend for
both the older, deprecated API gdk_device_grab() and the new gdk seat
API gdk_seat_grab(), but only if the requested capability is for the
keyboard only.

If a bad behaving application tries to make the window/display beep too
often, throttle the beep requests so that we don't end up filling the
Wayland socket queue.
The throttle is set to 50 beeps per second, which far more beeps than
will ever make any sense from a user experience point of view, but will
avoid terminating due to an excessive amount of requests.

For wayland clients, the startup notification ID is currently only set
from the DESKTOP_STARTUP_ID environment variable. As that variable is
only set for clients launched via exec(), startup completion is not
indicated correctly for DBus-activated applications unless an explicit
ID is specified - usually that is not the case, as the default handling
uses gdk_notify_startup_complete().
To address this, we need API to set the startup notification ID from GTK
as we have on X11.

Only update to using v2 headers/structs. The incompatible changes
to tool events are dealt with in the next commit. Pads aren't handled
in this commit either.
Debian stable currently ships with a 3.16 kernel, so
it doesn't have memfd available.
This commit adds shm_open fall back code for that case
(for now).

We currently use syscall() directly to invoke memfd_create,
since the function isn't available in libc headers yet.
The code, though, mishandles how errors are passed from syscall().
It assumes syscall returns the error code directly (but negative),
when in fact, syscall() uses errno.
Also, the code fails to retry on EINTR.
This commit moves the handling of memfd create to a helper function,
and changes the code to use errno and handle EINTR.
