The cursor texture, scale and position is captured separately and
overlaid on top of the preview, and on top of the final screenshot
image. This allows toggling it on and off post-factum.

As mentioned in the last commit, we'll split up taking screenshots into
creating a GPU texture first, and later saving that to disk as a PNG.
For individual windows it's already easy to get a ClutterContent with
the texture using meta_window_actor_paint_to_content (), for the stage
it's not that easy and involves a few extra steps including X11 specific
ones.
So introduce a new ShellScreenshot API which does all that and provides
the caller with a ClutterContent of the stage:
shell_screenshot_screenshot_stage_to_content ()

With the new screenshot UI we're introducing, we'll be capturing all
screenshots to textures on the GPU at first, and then create a PNG
stream from those textures at a later point. This will allow us to
present screenshots immediately to the user so they can inspect them and
select the right area before actually saving them to disk.
As a first step to make this work, introduce a new ShellScreenshot API
that writes an existing CoglTexture to a PNG output stream:
shell_screenshot_composite_to_stream ()

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
extensions using console.log() and similar functions don't show up as
'Gjs-Console' in users' system logs, we should call setConsoleLogdomain()
with 'GNOME Shell'.
This GJS API addition is only accessible using ECMAScript Modules (ESM),
this commit moves shell startup to a small init.js module and adapts
CI jobs to either handle or ignore it.
We can drop the .jscheckignore file when future versions of SpiderMonkey
allow for compile checks without validating module specifiers.

If an actor is not on any stage view, then it doesn't have a valid
resource scale, which will hit an assert later.
When that is the case (for example when running headless), we expect
that there is no valid theme node (yet) either, so simply moving
the clutter_actor_get_resource_scale() call after peeking at the
theme node is enough to avoid the crash.

Since we correctly call the `style_changed` vfunc superclass at the end
of our own function anyway, the style changes will get propagated to the
children of the scrollView inside `st_widget_real_style_changed` anyway.
So remove those unneeded and quite expensive (because they cause the
theme node to be regenerated) calls to `st_widget_style_changed`.

Properly compare the new icon properties of StIcon to the old ones on

This ports over gnome-shell and the theme test case to MetaContext,
instead of the various functions that were available before.
The test case is changed to use the special test context, used to
construct contexts for testing. It's part of a shared libary separate
from the main libmutter one.
This enables building mutter tests during CI, as the test framework is
needed by some of gnome-shell's tests.

`mallinfo` has been deprecated in favor of `mallinfo2`:

The fields of the mallinfo structure that is returned by the

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.

From [the spec](https://www.w3.org/TR/css-backgrounds-3/#shadow-blur):
> the resulting shadow must approximate (with each pixel being within 5%
> of its expected value) the image that would be generated by applying to
> 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`.

Having an inaccurate paint volume didn't matter until ae338af1e8, but
after that having too small a paint volume resulted in apparent clipping.

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.

Not when the main actor dimensions change. So now the shadows don't get

app_notify_events_added uses an intermediate builder to construct an
array that is then added to the main variant using g_variant_builder_add
which should clear the intermediate, but doesn't due to the way it is
passed: by value, rather than as a pointer.
This was debugged with the help of Eduardo Habkost, who believes it
works on x86 due to big structs being passed as pointers.
