This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.

The way code was structured made it easy to misunderstand things as the
surface actor of a window actor could change over time. So is not the
case, however, the intention of the corresponding "update" function was
so that a surface actor could be assigned to a window actor as soon as
the X11 window was associated with its corresponding wl_surface, if the
window in question came from Xwayland.
Restructure the code and internal API a bit to make it clear that a
window actor only once gets a surface actor assigned to it, and that it
after that point never changes.

We used to have wayland-specific paths for this in src/wayland, now we
have ClutterKeymap that we can rely on in order to do state tracking,
and can do this all on src/backend domain.
This accomodates the feature in common code, so will work on both
Wayland and X11.

We get a signed integer (-1 meaning "no workspace specified"), store it in
an unsigned integer, check for >= 0 (of course it is!) and set as the window
workspace (signed integer, -1 meaning "show on all workspaces"). What could
possibly go wrong?

The include <sys/random.h> was added to glibc-2.25, previously was

Fixes: a8984a81c "xwayland: Generate a Xauth file and pass this to
Xwayland when starting it"
https://gitlab.gnome.org/GNOME/mutter/merge_requests/633
Before this commit, sudo x11-app, e.g. sudo gvim /etc/some-file, fails
when running a Wayland session. Where as doing this under a "GNOME on Xorg"
session works fine. For a user switching from the Xorg session to the
Wayland session, this is regression, which we want to avoid.
This commit fixes this by creating and passing an xauth file to Xwayland when
mutter starts it. Just like gdm or startx pass a xauth file to Xorg when they
start Xorg.

When we're unfullscreening, we might be returning to a window state that
has its size either managed by constraints (tiled, maximized), or not
(floating). Lets just pass the configure size 0x0 when we're not using
constrained sizes (i.e. the window going from being fullscreen to not
maximized) and let the application decide how to size itself.

Attaching a NULL buffer should hide the cursor sprite. In these cases,
we we'll have neither surface nor buffer damage, so also update when we
just attached a NULL buffer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/630
When 252e64a0ea moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.
https://gitlab.gnome.org/GNOME/mutter/issues/597
Having a cursor role with a NULL renderer is valid state, and even desirable
on tablets (eg. after proximity out). In those cases it should be
interpreted as the cursor surface not being over any output.

We handle this in backend specific code for x11, so do the wayland
bits here. We can only honor this on applications that request focus
on a surface after a startup request, as we do need an explicit
surface to apply the workspace on (and we don't have additional clues
like WMCLASS on X11). Notably, gtk_shell1.notify_startup doesn't suffice.
Another gotcha is that the .request_focus happens when the surface is
already "mapped". Due to the way x11 and the GDK api currently work (first
reply on the startup id, then map a window, then request focus on that
window). This means the surface will ignore at this point
window->initial_workspace, so it must be actively changed.

On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
This argument instructs Xwayland to exit when there are no further
client connections. However we eventually want to handle restarts
ourselves (where, notably, mutter's will be at least the last client
connection).
This behavior could also induce race conditions on startup with clients
that quickly open and close a display, which is a more pressing issue.
Also, add -noreset back (which was also removed in commit 054c25f693 that
added -terminate). We don't want to reset the X server to a pristine state
in that situation either.

Code underneath seems to handle errors properly, or be x11-agnostic
entirely, this is apparently here to save a few XSync()s on X11. Just
drop this windowing dependent bit to make things cleaner.

It is now separated into meta_xwayland_start(), which picks an unused
display and sets up the sockets, and meta_xwayland_init_xserver(), which
does the actual exec of Xwayland and MetaX11Display initialization.
This differentiation will be useful when Mutter is able to launch Xwayland
lazily, currently the former calls into the latter.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

All child classes of `MetaWaylandShellSurface` as well as
`MetaWaylandSurfaceRoleXWayland` should only sync their actor if
their toplevel surface has a window. Currently this check is done
in the actor-surface class, but not all surface classes have a
toplevel window, e.g. dnd-surfaces.
Move the check to the right places.
For subsurfaces this assumes that the subsurface is not the child of
a window-less surface (like, as stated above, e.g. a dnd-surface).
If we want to support subsurfaces of window-less surfaces in the future
we have to extend the check here.
But as this is not a regression, ignore this case for now.

This object represents a Wayland selection owner. In order to invert the
FD direction (we hand an output fd, but want an inpu fd), create an
intermediate pipe so we can then create a GInputStream on top of it.

mutter would randomly crash in `send_xdg_output_events()` when changing
the fractional scaling:

This is because the xdg-output resource got freed but wasn't removed
from the list of resources.
Fix this by setting the user data of the xdg-output resource to the
corresponding `MetaWaylandOutput` so that the xdg-output resource
destructor can remove it from the list of resources.

Currently, it is assumed that if querying the EGL_TEXTURE_FORMAT of a
Wayland buffer succeeds it is an EGLImage. However, this assumption will no
longer hold on upcoming versions of the NVIDIA EGL Wayland driver which
will include support for querying this attribute for EGLStream buffers as
well. Hence, we need to check if buffers are EGLStreams first.

We use the input_method on both branches, but only check for its existence
when enabling the text_input. The case of focusing out shouldn't happen in
practice as we couldn't have focused in ever before, but still make the
check one level above so it's clearer that the text_input's IM focus cannot
be enabled without an IM implementation.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/432
Enable the OSK if receiving .enable consecutively (i.e. the
ClutterInputFocus was already focused). We specifically want to avoid
enabling the panel just because of focus changes within a surface (where
the .disable request across focus change would previously unfocus the
ClutterInputFocus). Prior state should be preserved if possible in that
situation.

When the touch_down event was not delivered to Wayland clients, there's
no point in keeping the touchpoint in our list, so remove it early
inside update() instead of removing it after the touch ended.
This fixes a crash inside touch_handle_surface_destroy() where the
assertion to make sure the surface is removed fails because the
touch_count of the surface never reached 0. This in turn happened
because a new sequence was added, while a (already ended one) wasn't
removed from the touch->touches list before. This caused the touch
counter to get incremented by 1 while no new sequence was added to the
list (because Clutter reuses sequence IDs, the old sequence is equal to
the new one, i.e. the new sequence already is present in the list).

Since commit 8df2a1452c (As pointed out by Robert Mader) we just happened
do this check when doing the first lookup for a Wayland surface for a
XWayland window, when we are later notifying upon surface creation we just
set the relation with no further checks.
The cases pointed out in the comment (eg. window changing decoration) might
presumably happen in a quick enough sequence that we have two scheduled
associations on the fly, so move this check to the more generic
meta_xwayland_associate_window_with_surface() which is called on both
immediate and delayed paths.

XWayland creates buffers of the combined size of all connected displays.
This can, especially on older but still in use hardware, exceed the limits
of the GPU.
If that is the case, use `CoglTexture2DSliced` instead of `CoglTexture2D`

Prior to this commit, MetaWaylandSurface held a reference to
MetaWaylandBuffer, who owned the texture drawn by the surface. When
switching buffer, the texture change with it.
This is problematic when dealing with SHM buffer damage management, as
when having one texture per buffer, damaged regions uploaded to one,
will not follow along to the next one attached. It also wasted GPU
memory as there would be one texture per buffer, instead of one one
texture per surface.
Instead, move the texture ownership to MetaWaylandSurface, and have the
SHM buffer damage management update the surface texture. This ensures
damage is processed properly, and that we won't end up with stale
texture content when doing partial texture uploads. If the same SHM
buffer is attached to multiple surfaces, each surface will get their own
copy, and damage is tracked and uploaded separately.
Non-SHM types of buffers still has their own texture reference, as the
texture is just a representation of the GPU memory associated with the
buffer. When such a buffer is attached to a surface, instead the surface
just gets a reference to that texture, instead of a separately allocated
one.
