delete_range_cb is set to be called before the text suppression done by
the gtktextlayout (otherwise it does not work properly). But at that
point the cursor position is not yet up to date. We thus need to move
the accessibility cursor notification to after the actual text
suppression, by using another callback.
This fixes cursor position in brltty screen reading.

Like other widgets, this returns a floating reference, so
(transfer full) is wrong. Just omit the annotation as others do,
thus implying (transfer none).

This is meant as an input to the font chooser.
We don't want the user to select a language, but
rather have fonts presented as they would work for
the current language. Therefore, do away with the
lang/script combo on the tweak page.
Really exclude the portions in the gtkfontchooserwidget.c that are built
when HarfBuzz and PangoFT2 are built, and update the Meson files to
exclude such sources as well from the main GTK SO/DLL and from the
gtk4-demo program.

Remove g_auto*() usage from these sources and use the traditional
g_free(), as g_auto*() are GCCisms (or CLangisms).
Also, don't include unistd.h unconditionally and stop including
langinfo.h and dirent.h, since they seem to be unused.

For some font features, we can figure out affected
glyphs, and show before/after. For some others, we
hardcode typical sequences.
Still to do: figure out how to find ligatures and
show them.
If GtkExpander:sensitive was FALSE, the arrow still got the normal fg
colour, which made it look clickable, in contrast to the adjacent label.
Fix this by adding selectors to catch the applicable :disabled states.
Note: Needing these may indicate an oops in generic styles elsewhere,
but I couldn’t see any, so let’s just get it looking right for now.

Add a new W32 backend-specific message filtering mechanism.
Works roughly the same way old event filtering did, but without
events (events are GDK/X11 concept that never really made sense
on W32), so there's no functionality for 'altering' events being
emitted. If an event needs to be emitted in response to a message
do it yourself.
Implemented like this, it should give better performance than
if we were to use GLib signals for this, since W32 sends a LOT
of messages (unlike X11, which doesn't send events as often)
all the time, and invoking the signal machinery on *each* message
would probably be bad.

This makes the code compile again, though obviously there have been
some substantial changes in how IM contexts work, so it's possible
that IME IM context doesn't work now.

Check for freetype2 version, because pangoft works with any version
(pangoft availability does not indicate that ft2 is new enough), unlike
GTK.
On Windows, since pangoft is optional, we check for the presence of
freetype2 .pc file first after finding that we have pangoft, and then
check for FT_Get_Var_Design_Coordinates() manually by looking for the
freetype headers and .lib first, and then looking for the presence of
that symbol, since freetype2's Visual Studio build system does not
generate a .pc file for us.

Turn the GtkFontChooserLevel field into flags, and
add flags for OpenType variations and features. The
motivation for this is to make font-features in the UI
opt-in, since applications need to support them by
applying the pango attribute.
