DMA buffers might be allocatable, but it doesn't mean the driver doesn't
fail when we try to allocate a buffer with an implicit modifier. Using
the proprietary NVIDIA driver for example, it will fail. Lets catch this
up front and avoid advertising DMA buffer support when we know it won't
work.

As of currently, we only emit .done() on actual changes coming from the
ClutterInputMethod/ClutterInputFocus. With the recent changes in the
interpretation of serials, it becomes more important now that the
compositor acknowledges every .commit done by the client, in order to
keep them feeding future IM state updates.

Compensate the protocol statelessness with our ClutterInputFocus
statefulness. This becomes more necessary now, since sending
consecutive .done() events is now considered acceptable behavior.

MetaCursorRendererNative only updates the cursor state when the
underlying texture changes. The cursor scale and transform do not
trigger updates. This results in wrong cursor orientations on rotated
displays. Use both texture changes and scale and transformation changes
to figure out when to update the cursor state.

When switching between the existence and not of a stage ClutterGrab, we
would correctly attempt to synchronize key focus from the perspective of
the Wayland clients.
But this synchronization should do its own checks about existing stage
grabs before determining a client window has key focus or not.
Add that check, so that grabs correctly unfocus the keyboard in Wayland
clients, in addition to pointers and touch.

When we get passed a "snippet" to the shaped texture, it's added as a
pipeline layer snippet to change how the source texture is sampled. When
we draw from a texture tower however we have allocated regular textures
which doesn't need any special layer snippet, so create separate
pipelines for those that doesn't use that snippet.

With Xwayland on demand, a number of maintenance X11 applications need
to be run first, before Xwayland starts accepting requests from the
normal clients, as soon as the WM_S0 selection is acquired by mutter.
On startup, mutter also sets a number of X11 properties that can be
queried by X11 clients.
Unfortunately, mutter acquires the WM_S0 selection before setting those
properties, so mutter and the first regular X11 client will race on
startup.
As a result, the X11 properties set by mutter on startup may not be
available to the very first X11 client when Xwayland starts.
To avoid that issue, make sure to take the WM_S0 selection last when
opening the display.

Currently, meta_xwayland_shutdown_dnd() is called from the handler
on_x11_display_closing() triggered from the signal "x11-display-closing"
hooked up from meta_xwayland_init_display().
Once the signal has been triggered, on_x11_display_closing() removes the
signal handler, disconnecting from the signal.
As meta_xwayland_init_display() is called from meta_display_new() which
is issued only once, the signal handler is not restored again.
As a result, meta_xwayland_shutdown_dnd() is not called anymore after
Xwayland has been restarted, but meta_xwayland_init_dnd() will check and
assert that the manager's DND object is NULL.
Basically, restarting Xwayland more that once will trigger an assertion
failure in mutter. That's even more of a problem with autoclose-xwayland
where Xwayland is expected to terminate when there is no meaningful X11
client remaining, which can happen multiple times during the lifetime
of a user session.
To make sure that meta_xwayland_init_display() is called for every new
instance of Xwayland, simply keep the signal hooked in place by not
disconnecting it when triggered.
This reverts commit 9a10b8ff94.
Even though, originally, this issue was first introduced with commit
b4fe1fdd95 ("xwayland: Make setup/teardown
a bit more symmetrical") which didn't actually kept 'x11-display-setup'
and 'x11-display-closing' connected.

For wayland meta_window_move_to_monitor sends a configure to the client
without actually moving the window, yet and the
meta_display_queue_check_fullscreen call won't detect any changes.
Checking for fullscreen in meta_window_update_monitor fixes the problem
because it is called whenever the window actually changed the monitor it
is on.

We rather confusingly still call a secondary display card that is
GPU-less (DisplayLink or other basic KMS device) a "secondary GPU",
so just because secondary_gpu_state is non-NULL doesn't mean we
can use it for rendering. The clearest indication of this is when
there is no EGL surface.

Since devices may be multiple things now, check all capabilities in order
to ensure all aspects of the device are correctly configured.
This change does the following observations:
- Devices that have TOUCHPAD | POINTER capabilities prefer the 'touchpad'
settings path. The regular pointer settings path is left for all
non-touchpads.
- Devices that are both a tablet and a touchscreen prefer the tablet
relocatable schema. This works for both aspects as the touchscreen
schema is a subset of the tablet one.
Other than that it's a rather boring, even if verbose search and replace.

We do not need to open code the ClutterInputDeviceType fetching from a
libinput_device, since we already created a native ClutterInputDevice that
has the right type.

We use meta_workpace_focus_default_window() to sync the input focus back
to a window after it was on shell UI, this is not really necessary on
Wayland, but it is on X11. What this function does internally is ask
MetaWindowStack about the topmost window and focus+raise that window.
In gnome-shell we set the input focus to the default window every time
the key-focus changes to NULL (see shell-global.c ->
sync_stage_window_focus()). Now when closing the alt-tab switcher and
activating a window while there's an always-on-top window on the
workspace, meta_workspace_focus_default_window() will focus that
always-on-top window right after closing the alt-tab switcher, making it
impossible to focus another window using alt-tab.
To fix this, make meta_workspace_focus_default_window() check if there's
an existing focus_window first, if there is, use that, and if there
isn't, resort to just focusing the topmost one.

This will allow us to reuse the keys and values more easily, as later

construct explict env strings for passing into special test cases.

We use get_window_for_event() to check whether an event happened on top
of a window or on top of shell UI to decide whether to bypass delivering
the event to Clutter. In case of crossing events though, we can't just
use the device actor to determine whether to forward the event to
Clutter or not: We do want to forward CLUTTER_LEAVE events which
happened on top of shell UI. In that case the device actor is already a
window actor (the pointer already is on top of a window), but the shell
still needs to get the LEAVE crossing event.
Since the event source actor got removed from the detail of
ClutterEvent, the context we're looking for (which actor did the pointer
leave) is now the target actor that the event gets emitted to. Since the
last commit, we also made event filters aware of this context by passing
the target actor to them, so use this context now to determine whether
we're on top of a window or not.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2321>
We'll need the additional context of which actor the event will be
emitted to in mutters event filter (see next commit), so pass that
target actor to the event filters that are installed.

Before scanning out the surface of a native client we have
to check the following attributes that influence the
relationship between buffer and the defined result on screen:
- buffer scale
- buffer transform
- viewport
In the future we can loose these checks again in cases where the
display hardware supports the required operations (scaling, cropping
and rotating).

Prior to 67033b0a mutter was accidentally including sizes for
configurations that were just focus state changes. This was not leading
to any known problems on the client side, but it was causing issues in
mutter itself when detecting whether a resize originated from the client
or the server.
Not including sizes in focus change configurations anymore however
revealed a bug in gtk. It was storing the window size when in a fixed
size mode (tiled/maximized/fullscreen), but not on any other server side
resizes. It was then restoring this stored size whenever there was a new
configuration without a size while in floating mode, i.e. the focus
change configurations generated by mutter after 67033b0a.
This change now addresses the issue 67033b0a was fixing in a way that
restores the previous behavior of always including the size whenever
sending a configuration.
