Add an adjust_fullscreen_monitor_rect virtual method to MetaWindowClass
and call this from setup_constraint_info() if the window is fullscreen.
This allows MetaWindowClass to adjust the monitor-rectangle used to size
the window when going fullscreen, which will be used in further commits
for a workaround related to fullscreen games under Xwayland.

If window decoration is modified within a short period of time, mutter
sometimes starts processing the second request before the first
UnmapNotify event has been received. In this situation, it considers
that the window is not mapped and does not expect another UnmapNotify /
MapNotify event sequence to happen.
This adds a separate counter to keep track of the pending reparents. The
input focus is then restored when MapNotify event is received iff all
the expected pending ReparentNotify events have been received.

When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.
As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.
Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.

Commit 09bab98b1e tried to avoid several workspace changes while in
window construction, but it missed a case:
If we have a window on a secondary monitor with no workspaces enabled
(so it implicitly gets on_all_workspaces = TRUE without requesting it)
and trigger the creation of a second window that has the first as
transient-for, it would first try to set the first workspace than the
transient-for window and then fallback to all/current workspace.
After that commit we only try to set the same workspace than the
transient-for window, but it gets none as neither is on a single workspace,
nor did really request to be on all workspaces.
Fixes crashes when opening transient X11 dialogs in the secondary monitor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/714
We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the
work on adding/removing it from the workspace, and everything that
happens in result.
Should reduce some activity while typing on the Epiphany address
bar, as the animation results in a number of xdg_popup being created
and destroyed to handle the animation.

As per commit 040de396b, we don't try to grab when shortcuts are inhibited,
However, this uses the focus window assuming that it is always set, while this
might not be the case in some scenarios (like when unsetting the focus before
requesting take-focus-window to acquire the input).
So allow the button grab even if the focus window is not set for the display

On Wayland, if a client issues a inhibit-shortcut request, the Wayland
compositor will disable its own shortcuts.
We should also disable the default handler for the button grab modifier
so that button events with the window grab modifiers pressed are not
caught by the compositor but are forwarded to the client surface.
That also fixes the same issue with Xwayland applications issuing grabs,
as those end up being emulated like shortcut inhibition.

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.

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.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that
surfaces for icon/mini-icon will be set, and just let it have NULL here.
It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

This function was added for historic reasons, before that we had GSlist's
free_full function.
Since this can be now easily implemented with a function call and an explicit
GDestroyFunc, while no known dependency uses it let's move to use
g_slist_free_func instead.

When an application stops responding, the shell darkens its windows.
If a window from a not-responding application gets unmanaged
then the shell will currently throw an exception trying to retrieve
the now-dissociated window actor.
That leads to a "stuck window" ghost on screen and a traceback
in the log.
This commit addresses the problem by making sure the effect is cleaned
up before the actor is disocciated from its window.

If a client maps a persistent popup with a placement rule, then resizes
the parent window so that the popup ends up outside of the parent,
unmanage the popup and log a warning about the client being buggy.

When a parent window is moved, attached windows (attached modal dialogs
or popups) is moved with it. This is problematic when such a window
hasn't been shown yet (e.g. a popup that has been configured but not
shown), as it'll mean we try to constrain an empty window. Avoid this
issue by not trying to auto-move empty windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/496
As per commit 43633d6b, we mark an unmanaging window as not focusable, while
this is true, it might cause not resetting the current focused window when
unmanaging it causing a crash.
Also this wouldn't allow to check if a window can be focused when unmanaging it,
so let's revert the previous behavior.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/462
For various error and warning messages, mutter includes a description of
the window, and that description includes a snippet of the title of the
window. Those snippets find their way into system logs, which then means
they can potentially find their way into bug reports and similar. Remove
the window title information to eliminate this potential privacy issue.
Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

It's a UI pattern that has been superseded by client-side decorations,
apps that used to set the hint have generally moved on to headerbars.
Given that and the limitation to server-side decorated X11 windows,
GTK4 removed the client-side API for setting the hint, it's time to
follow suite and retire the feature.

Commit 8d3e05305 ("window: Force update monitor on hot plugs") added the
flag `META_WINDOW_UPDATE_MONITOR_FLAGS_FORCE` passed to
`update_monitor()` from `update_for_monitors_changed()`.
However, `update_for_monitors_changed()` may choose to call another code
path to `move_between_rects()` and `meta_window_move_resize_internal()`
eventually.
As `meta_window_move_resize_internal()` does not use the "force" flag,
we may still end up in case where the window->monitor is left unchanged.
To avoid that problem, add a new `MetaMoveResizeFlags` that
`update_for_monitors_changed()` can use to force the monitor update from
`meta_window_move_resize_internal()`.

It relied on indices in arrays determining tile direction and
non-obvious bitmask logic to translate to _GTK_EDGE_CONSTRAINTS. Change
this to explicitly named edge constraints, and clear translation methods
that converts between mutters and GTK+s edge constraint formats.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
In order to allow a window with a custom rule placement to be moved
together with its parent, the final rule used derived from the
constraining were used for subsequent constraints. This was not enough
as some constraining cannot be translated into a rule, such as sliding
across some axis.
Instead, make it a bit simpler and just remember the position relative
to the parent window, and use that the next time.
This is a rework of 5376c31a33 which
caused the unwanted side effects.

With Wayland, a window is not showing until it's shown. Until this
patch, the initial state of MetaWindow, on the other hand, was that a
window is initialized as showing. This means that for a window to
actually be classified as shown (MetaWindow::hidden set to FALSE),
something would first have to hide it.
Normally, this wasn't an issue, as normally we'd first create a window,
determine it shouldn't be visible (due to missing buffer), hide it
before the next paint, then eventually show it. This doesn't work if
mutter isn't drawing any frames at the moment (e.g. the user switched
VT), as we'd miss the hiding before showing as e result of a buffer
being attached. The most visible side effect is that a window can't be
moved as the window actor remains frozen.
This commit fixes this issue by correctly classifying a newly created
Wayland window as "hidden".
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/331
Changes in window decoration result in the window being reparented
in and out its frame. This in turn causes unmap/map events, and
XI_FocusOut if the window happened to be focused.
In order to preserve the focused window across the decoration change,
add a flag so that the focus may be restored on MapNotify.
Closes: #273
On Wayland, xdg-foreign would leave a modal dialog managed even after
the imported surface is destroyed.
This is sub-optimal and this breaks the atomic relationship one would
expect between the parent and its modal dialog.
Make sure we unmanage the dialog if transient_for is unset even for
Wayland native windows.

A window placed using a placement rule should keep that relative
position even if the parent window moves, as the position tied to the
parent window, not to the stage. Thus, if the parent window moves, the
child window should move with it.
In the implementation in this commit, the constraints engine is not
used when repositioning the children; the window is simply positioned
according to the effective placement rule that was derived from the
initial constraining, as the a xdg_popup at the moment cannot move
(relative its parent) after being mapped.
