When resolving an icon name, we currently look in all themes in
order whether one of the requested names matches.
That means, a "keyboard" icon from the configured theme will
trump over any of "keyboard-shift", "keyboard-brightness" and
"keyboard-preferences" from lower-ranked themes (like "Adwaita"
and "hicolor").
That applies to custom icons we include in the resource, which
are added to the fallback ("hicolor") theme.
We are less bound by the named-icons spec than GTK, so we can
adapt the lookup to prefer the most accurate match to matches
from the highest priority theme.

This is a small one time leak if there is more than one entry in the
search path due to multiple iterations overwriting the old pointer
before finally going out of scope.

When loading a symbolic SVG, the original file is wrapped in
a header that includes a generated stylesheet with the
appropriate colors, plus an overall opacity.
The opacity value is clamped to values between 0 and 1, which
directly matched the alpha field of the GdkRGBA type. However
since we moved to StIconColors/ClutterColor, the alpha field
is now in the range [0..255], any alpha value other than 0 now
results in full opacity.
To fix, translate the [0..255] integer into a [0..1] double
before using it as opacity.

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
translating back and forth from GdkRGBA.

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.
With that and the previous adjustments, the new code is now
finally buildable.

Its use has been discouraged for years, and glib recently deprecated
it officially (while turning it around a small wrapper around malloc).
Don't let it sneak back in through some old GTK3 code.

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
change set, just use the standard i18n support from glib for now.

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.
