This makes it possible to use udev even for backends which are not
native. Specifically we want to start controling backlights in mutter
which has to happen for both native and X11.

As far as I can see this doesn't happen in practice, but theoretically
the uninitialized values can be used if:
1. `did_placement` is TRUE
2. `flags` contains both `META_MOVE_RESIZE_RESIZE_ACTION` and
also `META_MOVE_RESIZE_MOVE_ACTION`
3. `!meta_window_is_tied_to_drag (window)` is FALSE
In that case, the `frame_rect` variable (with uninitialized values) is
passed to `unconstrained_rect`, then passed to `constrained_rect`,
then finally the (uninitialized) X and Y values are read in the
`if (did_placement)` branch.
This is probably a regression from 3047b2ce261. I don't know if this is
the appropriate fix.

This is needed to allow tests to manipulate the behavior of the test
shell plugin during startup. Since the plugin is created and started
when the MetaDisplay is created, it needs to be handled via MetaContext,
by setting the options after creating the context, but before starting.
For simplicity reasons, make the options an opaque GVariant, passed via
a an `"options"` property when the plugin object is created, if the
passed options is non-NULL. Only passing the options when non-NULL
allows for backward compatibility.

This disables the visibility change effects for the dragged window,
which makes it feel a bit smoother.
TODO: Double-check whether this is indeed desirable. Note: ChromeOS imp
does this and Chromium-X11 used to do this at client side.
Status:
- [x] Basic window drag triggering
- [x] Exclude the dragged window from event targets
- [x] Event forwarding (window drag vs wayland grabs)
- [x] Offset calc relative to toplevel geometry
- [x] Attach already mapped windows
- [x] Properly support not-yet-mapped windows
- [x] Disable visibility change animations
- [ ] Dnd events stream adaptations

- This adds a new ClutterActor parameter to meta_compositor_drag_window
and meta_window_drag_begin such that it's possible to inject an
external grab actor, which is then used to implement a "non-grabbing"
mode that allow a MetaWindowDrag to be used in conjunction, for
example, with a Wayland drag-and-drop session;
- This new API is going to be used to implement the toplevel drag
protocol in a subsequent commit.

The MetaWindowConfig can indicate whether the configuration reflects on
the initial configuration, before the window is first mapped.
Add a smaller helper (private) window function to create the appropriate
"type" of MetaWindowConfig depending whether the window was already
showed or not.
This is preparation work for the following commits where this function
will be used.

Use the meta_window_is_fullscreen() API instead of accessing the
fullscreen field of the MetaWindow structure directly.
This is both a (small) cleanup and preparation work for the next commit.
No function change (intended).

This is intended to be used in place of the window rect and fullscreen
flags.
That will also allow for a pre-configuration signal to be added, passing
the configuration so that a plugin can tweak the configuration before it
gets applied first.

In acbb14f34bc8fee14e77db3c100e5d116d8e3d60, we have dropped the
is_client_decorated except it was still being used by gnome-shell
to adjust the window coordinates in case it is using server side
decoration.
Instead of re-adding the same function, expose a new function that
takes care of getting the whole client area while taking into account
SSD for X11 clients.

To avoid mostly going through struct fields in macros as we might soon
move those first to a WindowConfiguration & maybe even make the window

we will just remove the whole thing and use glib helpers directly as

It will be used to force the color state of all monitors to be as if
they managed to turn on HDR mode. This is useful for debugging shaders
in an environment where an HDR mode capable display is not available,
such as the nested mode.

While the events when processing keybindings are quite obviously
key events, the individual structs are all opaque and all public
API is provided by the generic ClutterEvent type. That means that
any handler that uses the passed in event must cast it to
ClutterEvent anyway, so drop the cast to ClutterKeyEvent when
processing key events.

Allow saving the session gvdb file in the background, with as little
overhead in the main thread as possible. We still need to serialize
all created/deserialized MetaSessionState to a GVDB hashtable there,
in order to avoid these being poked from the async task thread.

Make this core object own the MetaSessionManager, for the window management
code to access.
At this level, we will be able to integrate with systemd notification
system, and use systemd fdstore to keep the mapped memory warm for
us for the case of soft reboot. This is at the moment not implemented
here.

This core object will be the manager of "client sessions", allowing
the windowing-specific paths to generate MetaSessionState objects to
track their clients.
This object is unused at the moment, and will be integrated in later
commits.

This is an abstract base class to implement a "client session",
carrying the accounting of the windows, and allowing to serialize/read
their state into a Gvdb table.
Since different windowing backends may require slightly different
data to be saved for each window, this is meant to have windowing-specific
implementations.

A nick property is a bit similar to the nick of a GObject property, in
that it's a shorter version of the name. It's intended to be used to
store state on the file system, where the state depends on the desktop
environment being used. E.g. gnome-shell sets the name "GNOME Shell",
which is, if no nick is explicitly set, transformed into the nick
"gnome-shell", which will be used for file paths.

Allow scale-aware Xwayland clients to scale by an integer scale
themselves, instead of letting them render them at 1x scale and then
scaling up the texture, making it look blurry.
When monitor framebuffers are scaled, this special cases Xwayland and
sends output regions in a way that Xwayland think everything is N times
as large as the logical region, where N is the ceil of the max monitor
scale.
This is done by introducing a "stage" vs "protocol" coordinate space for
X11, where the "protocol" coordinate space is "stage" multiplied by a
scaling factor.
Xwayland thus will have its own "effective scale", sent via
wl_output.scale. The effective Xwayland scale is also used for the
internal MetaWaylandSurface scale internally, unless there is a viewport
dst size set on the same surface, in which case the scale is still set
to 1, to not interfere with wp_viewport semantics.
We're guarding this behind a new experimental feature
"xwayland-native-scaling", which can only come into effect when enabled
together with "scale-monitor-framebuffer".
[v2]:
Move stage_to_protocol/protocol_to_stage to generic window class.
This means parts that aren't aware of any windowing system specific
logic, only that coordinates originate from there for a given window,
can still get their coordinates properly handled.
In particular, this means coordinates from IBus that originates from the
client, can be scaled properly when that client is using X11.
Also make them properly introspected.
[v3]:
Split up coordinate transform API.
Make it one that takes a MtkRectangle, and another that takes a point.
This means the rounding strategy becames explicit when transforming a
point, while when it's a rectangle, it's still always "grow".

Toplevels get the main monitor from their MetaWindow and have no main
monitor when the toplevel is not mapped.
Subsurfaces get the main monitor from their parent surface.
DnD and cursors get the main monitor from the current cursor position no

This leads to possibly missed key release events being propagated down to
clients, and in the case of X11 clients, to stuck keys e.g. after switching
workspace with Ctrl+Alt+Left/Right and ending up with a X11 client focused.
