...even if PangoFT2 is not present, provided that Pango 1.44.0+ and
HarfBuzz 2.2.0+ are installed. The demo now has added support for later
Pango versions that use HarfBuzz for shaping on all supported platforms.
...if Pango 1.44.0+ and HarfBuzz 2.2.0+ are available, otherwise we
stick on to the current code path.
This way, we can have people build and run the demo even without
PangoFT2 if Pango 1.44.0 or later and HarfBuzz 2.2.0 or later is
installed.
This way, we can share the demo listing to be used in other build
Makefile-based build systems, such as the auxiliary NMake Makefiles used
to generate the various sources.
Various files are in git but not in dist tarballs. Some of them look
like potentially useful references for downstream distributors.

open() in text mode should never be used without an encoding because it defaults
to the locale encoding which is rarely what is wanted.
This fixes the Windows build in some cases (depending on the locale/paths used)
Comments matched to reassure the compiler that fallthrough is
intentional are supposed to precede the case or default keywords, at
least in GCC, so the one here did not suppress the warning with GCC. We
can just the if condition and put the comment at the end to solve that.

If we detect HarfBuzz and PangoFT2, GtkFontChooserWidget uses them. So
we need to add CFLAGS and LIBS of them to GTK_DEP_CFLAGS/LIBS. If we
don't add them, MinGW build fails to link.
...in place of math.h, as we are using round(), which is possibly not
provided by the compiler since we don't require a C99 compiler in
GTK+-3.x and gtk/fallback-c89.c does include math.h anyways.
This class is not added by any widgets nor themed by Adwaita/HC.
However, it is presented here as if it does something. It doesn’t.
But we changed the 2 buttons with the .raised class to use symbolic
icons, unlike their ‘unraised’ counterparts, which is unnecessarily
confusing and might make people think .raised affects icons somehow.
So, make them use the same icons in all cases; that way, if .raised is
ever made to do anything, 6 years later, what it does will be clear.

And rename it to "Touch and Drawing Tablets", since it's no longer about
"axes" really.
As for pad support in the demo, just keep it "simple", make the
controller handle all pad devices, and make all the actions have the
same callback.

After introducing the CSS blend mode enum values and including
the background-blend-mode CSS property, it is very important to
actually provide an example of the new feature.
This patch adds a new demo to gtk3-demo which shows how the
background-blend-mode CSS property works.
