Those are GTK internals that don't apply to us. Without the distinct
"screen's default icon theme", we also don't need custom theme support,
and can just always track the theme from StSettings.

The GTK code dates back to a time when "gchar" and friends were
still considered a good idea. Replace them with standard types
except for "guint" (I'm lazy) and GtkIconCache code that relies
on glib's byte order macros.

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.

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%.

Since commit 5a23c96bd918 we use EXPLICIT_NOTIFY for properties,
however there are still cases where we still notify unconditionally
from the setter, because we don't check the existing value first.

GTK4 added a convenience property for icon-only buttons. While that
use case is not quite as common in the shell as in GTK apps, it still
seems common enough to mirror the GTK API.

When neither the theme node itself nor any of its parents specifies
an explicit text direction, we default to aligning to the left.
That's a good default for LTR locales, but for RTL aligning to the
right is a better one.

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.

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.
This effectively reverts f74c07b9acbdc6945ca37f86bc680701f048f174

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.

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.

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.

- 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

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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2085>
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.
