This is a backport of the code in GTK4 where we can use the font
features that is given to us via HarfBuzz if we have Pango 1.44.x and
HarfBuzz 2.2.0 or later installed, even if we do not have PangoFT2
aavilable.
Since Pango 1.44.x depends on HarfBuzz for all platforms after 1.44.0,
we could take advantage of that and build the support in
GtkFontChooserWidget.
Add a directive that is to be used by Visual Studio compilers via the
Visual Studio projects to link to harfbuzz.lib automatically, so that
this support can be linked properly if we have the required Pango and
HarfBuzz headers and lib's installed. Meson builds via Visual Studio
should handle this automatically, since pkg-config is being used there.
Since HAVE_PANGOFT2 and HAVE_HARFBUZZ is not defined by default in the
Visaul Studio projects, we will leave it up to the user to enable them
themselves and put in pangoft2-1.0.lib and harfbuzz.lib in the project
settings by themselves, or they could use Meson, as we did before.
When the compose file is a symbolic link, take the link itself's
modification time into account (in addition to its target's) in
determining whether to invalidate the compose cache.
This is useful e.g. on NixOS systems where the compose file might point
to a store path with an irrelevant modification time, and we want the
cache to expire when the symlink itself changes.

Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
In macOS-12.sdk CGContextConverSizeToDeviceSpace returns a negative
height and passing that to CGContextScaleCTM in turn causes the cairo
surface to draw outside the window where it can't be seen. Passing the
absolute values of the scale factors fixes the display on macOS 12 without
affecting earlier macOS versions.
Like the Visual Studio 2012+ projects, copy the Visual Studio 2010
projects and replace the items in there as needed, so that we can
obtain Visual Studio 2022 project files, since they are all in the
MSBuild format.
The rc.exe that comes with the Windows 11 SDK does not allow one to include
winuser.h directly in the .rc scripts, so make sure that we do not try to
generate the final gtk.rc with it, but instead include windows.h with
WIN32_LEAN_AND_MEAN defined.
The resource compiler in the Windows 11 SDK does not allow one to include
winuser.h directly in resource scripts (.rc) with a rather cryptic error
message, so fix generating the .rc file to embed the UAC manifest by including
windows.h with WIN32_LEAN_AND_MEAN instead.
Broadway is the only GTK+ backend that throws an error on stderr for a
"display server" connection failure.
This causes problems when gtk_init_check() is used and unexpected error
output is generated such as with hotdoc, which fails when generating a
GTK plugin's documentation instead of overlooking the issue.
"Unable to init server: Could not connect: Connection refused"
It is necessary to signal the search engine that we are finished and
that we found something for it to reliably show the results. It would
sometimes work anyway since it is sufficient if any backend signals
completion. However if GtkSearchEngineModel was the only backend
returning results then things would break.
