A property for reversing the visible order of children is a bit odd.
It has also been unused by actual gnome-shell code since 2010, and the
somewhat related pack_start()/pack_end() API in GtkBox(Layout) is gone
in GTK4.
With that in mind, turn the property into a no-op and deprecate it,
so that it can be dropped next cycle.

Replace deprecated functions with their direct replacements:
- dep.get_pkgconfig_variable() → dep.get_variable()
- prg.path() → prg.full_path()
- source/build_root() → project_source/build_root()
In one case we need meson.global_source_root() that was only
added in meson 0.58, so bump the requirement to that.

Since commit 1807be1, we clear the fallback icon when a window is
removed, and notify the icon change. The notify call currently
happens after removing the window from the running state, but
before syncing the state (and possibly clear the running state
altogether).
That state is inconsistent and results in an assertion hit when
some code tries to re-fetch the icon in response to the notify
call.
Address this by updating the state before clearing the fallback
icon, so that the app will be in the correct STOPPED state after
removing the last window.

We were not properly tracking the window used for the fallback icon.
This could trigger a crash, as disconnection of the signal handler might
happen on the wrong window, which in turn could cause the icon change
notification to happen on a destroyed ShellApp instance.
Fix this by tracking the window used for the fallback icon. Disconnect
the icon notify callback explicitly for this window only when it is
removed.
Also, just to be extra safe, make sure that the icon is never NULL even
if x11_window_create_fallback_gicon should return NULL for some reason.

We currently track windows via MetaWorkspace's ::window-added and
::window-removed signals. Those aren't emitted for override-redirect
windows though, as those aren't actually located on any workspace
(see https://gitlab.gnome.org/GNOME/mutter/-/blob/gnome-41/src/core/window.c#L1322).
While that shouldn't be an issue as there's no good reason to look up
the ShellApp of an OR window, extensions can make modifications that
result in OR windows ending up in places that assume that every window
has an associated ShellApp.
We can either
- accept that extensions break stuff (including badly)
- carefully handle app-less windows everywhere
- extend tracking to OR windows
Opt for the last option, as that's the most user-friendly and least
disruptive one.
It's also simpler to track ::window-created and ::unmanaged, as we
don't have to track workspaces or windows moving between workspaces.

The window-type property may change, and with it the skip-taskbar
property that decides whether we consider it "interesting".
As a result we can end up showing untracked window, i.e. one
which does not have an associated app.
Cover this case by simply tracking all windows regardless of
their type. This won't change the app's running state, as that
is solely based on the skip-taskbar property (which is enforced
for all previously excluded window types).

Windows from some applications, such as guake, are created as showing on
all workspaces. When these windows are put on the workspaces via
set_workspace_state() during construction, the first time the window is
added to a workspace in the loop triggers the shell app tracker which
then tries to move the window to its startup workspace. This makes the
window unsticky which triggers another set_workspace_state() which
tries to remove the window from all workspaces, but currently it is only
on the first one and then adds it to the startup workspace. Once that is
finished, the first set_workspace_state() continues adding the window
to the remaining workspaces, despite the window now no longer having
on_all_workspaces set to true.
When the window is now unmanaged, the window according to its internal
state is only found on the startup workspace, so it will only be removed
from that. This causes the assertion to fail that checks that the window
is no longer present on any workspace after this.

Icons that are changed while an actor is not mapped may not have a theme
node associated with, and thus we'd end up not updating them at all.
In fact we return early in st_update_icon(), and this was not an issue
until commit 0b1dfbf6f3, because we'd end up to update the icon anyways
once the style was changed (and so with a valid theme node), but since
such change we might not updating the icon if no theme detail changed.
To prevent this, add a flag to require an icon update when the theme
changed, if no successfully update happened earlier.

GJS added a console module that extensions may start using. To ensure that

If an actor is not on any stage view, then it doesn't have a valid

Since we correctly call the `style_changed` vfunc superclass at the end

Until now, the absence of a `background-color` would cause `box-shadow`s
to be invisible. That was a bug because `box-shadow` is meant to be either
the color specified in `box-shadow`, or if none was specified then the
foreground `color`.
There is nothing in the spec that says the `box-shadow` rendering should
depend on `background-color`, so separate them. This ensures `box-shadow`
is rendered even when `background-color` is absent or transparent.

> the shadow a Gaussian blur with a standard deviation [sigma] equal to
> half the blur radius
This does not change the value of `sigma`, it only corrects the value of
`sampling_radius` used to size the shadow texture. Since the texture is
no longer being slightly oversized it won't get scaled down when rendered
according to the dimensions provided by `st_shadow_get_box` in
`_st_paint_shadow_with_opacity`.

When a GTK app is started, we create a corresponding GtkApplication
proxy to monitor the app's busy state. If the app is stopped before
the proxy request finishes, we cancel the cancellable before clearing
the running state.
Usually we clear the cancellable once it is no longer needed, namely
when we got the proxy. However when the request was cancelled, the
cancellable has already been cleared, and if there's a cancellable,
it belongs to another request (because the window was added again,
for example when moving between monitors).
Leave that cancellable alone in that case, so we can cancel the
second request as well if necessary to avoid a crash when trying
to set the proxy on a cleared running state.

With commits fab39bbea5 and

ClutterActor API: clutter_actor_invalidate_paint_volume()
Given that this commit was applied to the 40 stable release, it broke
ABI compatibility with mutter, which is something we guarantee between
stable releases. So use GModule to dynamically find the symbol in our
loaded libraries. If it exists, use it and invalidate the paint volume.
If it doesn't exist, libmutter is still at version 40.0 and we don't
need to invalidate the paint volume.
This also adds a dependency on gmodule. We need to link against gmodule
to use g_module_open() and g_module_symbol() APIs.

StWidget is overriding ClutterActors get_paint_volume() vfunc to adjust
for overpaint of things like box shadows that get set in CSS, it does

just invalidate the paint volume when the theme nodes paint_equal()

Since commit 770231, StImageContent implements the GIcon interface, which
allowed us to represent all application icons as GIcon (app-info, X11 icon
property or themed fallback icon).
While that change made for a nicer ShellApp API, it did introduce a
conceptual issue in st_texture_cache_bind_cairo_surface_property():
GIcons usually represent static icons, while the ClutterContent
returned by that method updates automatically when the bound property
changes.
Address this by tracking the MetaWindow:icon property in ShellApp, and
update the fallback icon when it changes. With that, a GIcon object
always represents the same icon, and any icon change is reflected
by a corresponding GIcon change.

This reverts commit 87558efbf1.
The commit did not fix the bug it was supposed to fix, it just
complicated the code. The hopefully correct fix is in the previous
commit.
The point of this commit was to ensure everything gets removed when
bind->source gets removed. This however was already the case since the
signal handler was already connected to bind->source and has a
destructor registered that takes care of everything. And since gobject
destroys its signal handlers before it clears the weak refs, this new
weak ref was effectively never being used.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1718>
If the icon surface of a window got updated and its type or format no
longer match what we expect, st_texture_cache_reset_texture() might
overwrite the existing image in the bind with a new image, while still
keeping the weak ref on the old image. Due to this the old image might
trigger a st_texture_cache_on_pixbuf_notify() after the bind has already
been freed by g_signal_handlers_destroy() in the bind source. While this
usually would remove the weak ref, the weak ref it tries to remove is
on the new image, not the old one. The call to
st_texture_cache_on_pixbuf_notify() then tries to read the already
free'd memory from the bind which causes the cast to G_OBJECT to fail,
resulting in the crash.

Changing the workspace of a window causes the window tracker to remove
and add it to the app again. If this happens from within
_shell_app_add_window() before the window has been added to the windows
list, this will cause the check that is supposed to prevent adding the
same window multiple times to fail and the window to be added twice.
The app will then be considered still running after the last window has
been closed. Then when clicking on the corresponding app icon, the shell
would attempt to switch to a NULL workspace for the closed window
instead of starting a new instance, resulting in a crash.
Changing the workspace also needs to happen after increasing the
interesting window count, because otherwise removal of the window by
the window tracker would trigger a uint underflow leading the app to be
considered running with UINT_MAX interesting windows, despite having no
windows, leading to crashes right after launching the app.

Launching applications on a particular workspace works through
launch contexts and startup notifications. While this is no
longer required by a launcher/WM split, in theory this allows
us to reliably identify the correct window to apply startup
properties to.
However in practice we fail more often than not: Missing support in
toolkits, differences between display protocols, D-Bus activation
and single-instance applications all provide their own pitfalls.
So instead, take advantage of the fact that launcher and WM live in
the same process, and go with the unsophisticated approach: Just
remember the last workspace that was requested when launching an
app, then move the next window that is associated with the app to
that workspace.
This will break X11 applications that set an initial workspace, but
that's legacy functionality anyway (given that there's no wayland
protocol for that functionality), and seems a price worth paying
for making launching apps on workspaces more reliable.

of the effect ending abruptly past the given extents.

What the blur shader does is going n_steps in each direction (e.g. in case
