ClutterEffects are responsible for queueing redraws when their
properties change (and StScrollViewFade is a good citizen already), also
Clutter itself should queue a redraw when adding/removing an effect.
Users of Clutter should never have to queue redraws themselves (unless
they're implementing a custom ClutterEffect or ClutterContent), so don't
queue a redraw here.

The fade effect can also be added to the scroll view programatically
instead of using CSS via the st_scroll_view_update_fade_effect() API.
We make use of this API in the appDisplay, but since commit ba547ec1d
the fade margins get overridden to 0.0 from the ::style-changed handler.
Fix this by only setting the fade margins when CSS actually defines a
custom vfade/hfade offset.

Since now the resource consumption of the "style-changed" signal
handlers should be significantly lower, we can start emitting the signal
in all cases again as it was originally intended. This fixes some small
visual issues, like the battery percentage in the panel only being shown
on hover or updating the size of StIcons on scale-factor changes.

Just like with the last commit, listen to some ClutterText property
changes to catch style changes that were trigerred by
_st_set_text_from_style() and invalidate the shadow spec on changes.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1744>
We update a few properties of ClutterText when the CSS changes via
_st_set_text_from_style() (which we call when receiving the
style-changed signal).
Right now we simply invalidate the text shadow every time we receive the
style-changed signal, but we're going to change that with the next
commits. To ensure the shadow still gets invalidated on CSS changed that
might affect the shadow, listen to a bunch of property changes that will
get notified when any property that affects the shadow changes.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1744>
When text shadows are used, the cursor indicating the current position
also casts a shadow.
This means we have to regenerate the shadow texture after the cursor
position changed, so invalidate the shadow in that case.

It's slightly more efficient not having to do property lookups. While
that is unlikely to be a concern for the properties in question, it's
still good practice and makes the code base a bit more consistent.

We are now consistently calling notify() when a property does change.
With that we can opt out of g_object_set()'s implicit change notifications,
so that notify is only emitted when a property *actually* changes.

- move all icons to the icons directory
- rename some icons to be more meaningful
- put all icons on a resource sheet
- update references to icon name changes
- deprecate icons for those in standard set

The calendar's timezone cache holds only timezones already received
or added to the calendar, thus when asking it for a timezone for "the first
time", it returns NULL and a wrong timezone is used instead.
The get_timezone() does not do any I/O when the timezone is already cached
on the client side, thus it's fine to use it.
This could exhibit with non-recurring events, which use custom time zones,
in which case the event is shown in a wrong time.

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 ()
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1954>
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).
