StIconTheme was added as a private implementation detail of
StTextureCache, but it turns out that some extensions do
make heavy use of GtkIconTheme.
Allow them to port away from GTK by exposing StIconTheme to
introspection.

There's a few things going on here, that unfortunately must
happen in lockstep:
- The gnome-desktop-3.0 dependency gets replaced by gnome-desktop-4
and gnome-bg-4. The code in ui/background.js required minor updates.
- The libnma dependency gets replaced by a libnma4 dependency. The
code in misc/modemManager.js required minor updates.
- The gtk3 dependency is torn down everywhere but tests. Some
missing GdkPixbuf dependencies had to be added to compensate for
its lack.
- gtk_init_check() is no longer called
As a result, we replace a hard gtk3 dependency with a soft gtk4
run-time linking one, only added indirectly through gnome-bg-4
and libnma4.

Avoid using it by... guess it... yes! Copying the function
into an utility. This helper function to convert between

Reimplement tray icon support on top of NaXembed. NaTrayIcon now
becomes a subclass of this type, replacing GtkSocket. The
ShellTrayIcon wrapper now embeds directly a NaTrayIcon, the
ShellEmbeddedWindow GTK widget and ShellGtkEmbed ClutterClone
objects are no longer necessary to wrap a NaXembed socket window.

We include a private hidden .desktop file for evolution's calendar
component, so that we can explicitly open that component when
evolution is configured as the default calendar application.
That's because the evolution developers didn't want to ship
additional .desktop files at the time, but they have since
then included a desktop action that can be used for the same
purpose.

Since commit a1d650ce27, window title changes are listened for in the
ShellWindowTracker in order to emit ::tracked-windows-changed when
there are window title changes.
The rest of the things that happen in between (removing the window
from a ShellApp, possibly have it destroyed, and possibly creating a
new ShellApp to re-insert the window) are superfluous and even result
in the altTab switcher popup ending up confused about the applications
available.
Only emit the signal so changes can be followed on D-Bus, but avoid
the ShellApp fiddling otherwise.

The ClutterFrame argument was added to several signals with mutter commit
08b0e563d4d0088e19d24f3199626a2d27349d09. We have a bunch of after-paint
handlers in gnome-shell too, and updating those was apparently forgotten,
introducing subtle memory corruption that was luckily easy to track down by
running gnome-shell with ASAN enabled. Let's fix that and add the additional
argument to all the signal handlers.

We already have ClutterColor to represent a color, and StIconColors
to hold color information for symbolics from CSS. Now that we moved
GtkIconTheme in-tree, we can make use of those types instead of

We are still linking to GTK, and extensions may import GTK for
whatever reason, so avoid conflicts by moving the copied GTK
code into our namespace.

Its use has been discouraged for years, and glib recently deprecated

The GTK code predates the G_DECLARE_*() macros, so it's under- standable
that it still does all the boilerplate manually. We
don't have that excuse in 2023, so move the the standard macros.
There is no reason for GtkIconTheme to be derivable, and as that
means that the instance struct itself is private, stop adding
separate private instance data.

GTK uses its own private i18n header, which most notably defines
an I_() macro for interning static strings. That may be a worthwhile
idea for the entire codebase, but as it's out of scope for this

Those are GTK internals that don't apply to us. Without the distinct

The GTK code dates back to a time when "gchar" and friends were

GtkIconTheme's headers are split between a public and a private
one. We won't expose the icon theme API at all, nor do we need
to access anything beyond what the texture cache is currently
using, so merge the private header into the implementation.

GTK4 changed icon loading significantly, it is now closely tied
to snapshots and paintables. This makes a port highly unrealistic,
so to avoid staying stuck on GTK3 forever, copy the relevant code
into the tree.
The code is unmodified except for the include names and replacing
some stray tab indentation. It is still full of GTK internals, so
it will take a while before we can actually build it.

This means the screen share window view gets updated also when the title
of a window changes. This is important since it often changes shortly
after mapping, which would otherwise go unnoticed by
xdg-desktop-portal-gnome.
An example is launching Files and it showing up as 'Loading..', or
launching a terminal, and it not showing the proper title (current
directory), but some place holder that is never visible on the
application window.
Adding it to the window tracker instead of in introspect.js itself is
for convenience - there is no per window signal tracking there, and it
already listens to the signal emissions about changed windows.

This allows neat tricks like first arranging the script `fakegdb`:
```sh
function ignore_gdb_arg() {
if [[ "$1" == "--quiet" ]] || [[ "$1" == "--args" ]]; then
return 1
else
return 0
fi
}
ignore_gdb_arg "$1" || shift
ignore_gdb_arg "$1" || shift
echo exec "$@"
```
then running
```sh
meson test -C build -v perf-basic --test-args '--wrap "gdb --args"' --gdb --gdb-path `which fakegdb`
```
To make it possible to run the perf test case with gdb running the
actual gnome-shell.

This test runs all of GNOME Shell using the headless backend inside a

If one wants to run tests the non-installed gnome-shell, that currently
fails as gnome-shell the executable attempts to link against
./build/src/libgnome-shell.so, but when GObject introspection tries to
find what library to link to for Shell, it goes to the installed
libgnome-shell.so, causing two different versions of libgnome-shell.so
to be loaded.
This, however, can be avoided thanks to meson adding $ORIGIN paths to
relevant libraries before installing an executable. What this means in
practice is that we can inspect ourself upon startup, discover whether
the RPATH/RUNPATH header contains $ORIGIN, and if so, expand it to the
directory containing the executable, and prepend the introspection
search paths with said directory.
This effectively means that the introspection machinery now finds the
same library that the linker linked the gnome-shell executable with,
making it run successfully.
It's not possible to use $GI_TYPELIB_PATH since
g_irepository_prepend_library_path() takes precedence. There is no
"append" variant of that API.

Commit 9168f6055e marked the parameter as nullable, which is in
conflict with the precondition check. But given that NULL is
valid for the underlying ClutterText (and GtkLabel accepts it
as well), there's no strong argument for disallowing NULL, so
remove the precondition check.

Only when part of it is actually visible.
Because the central rectangle is generally the largest part, this
eliminates most of the shadow's render time. For example, animating
`.workspace-background` by tapping Super, the shell's overall render
time is reduced about 15%.

WorkspaceBackground's allocate is a hot function called every frame
during overview animations. Port it to C.
While we're at it, cache the work area and the monitor geometry, which
do not need to be re-fetched on every allocation.
This reduces the average WorkspaceBackground allocation time from
0.134 ms to 0.017 ms. With four workspaces, scrolling the overview sees
an average WorkspacesView allocation time improvement from
1.104 ms to 0.678 ms.

Even though GNOME Shell is not explicitly using structured logging via
G_LOG_USE_STRUCTURED, GLib uses it as default since 2016 [1], and so
we're de facto using it.
As per this, if backtrace on warnings is enabled, it is ignored since the
log handler isn't used anymore, and no dump is printed.
Thus, replace the default log handlers with writer functions instead, honoring
backtrace-warnings debug string.

We started tracking all windows to make sure the assumption that any
window can be match to an app holds. It is not expected however to
ever represent OR windows in the UI, so it seems better to exclude
them from get_windows() instead of expecting everyone to filter the
return value themselves.
(The returned list still includes "uninteresting" windows like attached
dialogs, which can be important for cases like the correct MRU order in
alt-tab)

As first mentioned in commit 672171093, the CSS spec defines shadow
colors independently from the colors casting the shadow. It's not
a physical light simulation so a shadow is allowed to be a different
color from texture casting it.
This means we only care about the shape of the source where alpha
values of zero are adjacent to alpha values of non-zero. And all such
non-zero pixels should be treated as fully opaque for the purpose of
shadow generation. While this would be wrong for a physical light
simulation it does allow us to cast shadows around semi-translucent
shapes and better support CSS.

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.

Just like with the last commit, listen to some ClutterText property

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.
