The font features demo started calling the Harfbuzz API directly
starting from commit 9de3b24c20. Harfbuzz
is an implicit dependency of Pango on some platforms, but it's not part
of the public dependencies; this means that we cannot expect to link to
Pango and automatically get Harfbuzz symbols to link against —
especially when things like --as-needed are in play.
This change triggered build failures on non-Unix platforms, fixed by
commit 2a9967731a, as well as build
failures in Continuous, with this error message:
/usr/lib/gcc/x86_64-gnomeostree-linux/4.9.3/../../../../x86_64-gnomeostree-linux/bin/ld:
font_features.o: undefined reference to symbol 'hb_tag_to_string'
//lib/libharfbuzz.so.0: error adding symbols: DSO missing from command
line
collect2: error: ld returned 1 exit status
In order to get the font features demo to build everywhere we should
take an explicit, though optional, check on Harfbuzz, and conditionally
build the font features demo with the right compiler and linker flags.
The fonts features demo now uses fontconfig APIs via PangoFT2, which makes
the code not build on non-Linux, so only include this demo in the build
on UNIX.
Add more features to the list, allow selecting script/language
from the set that is supported by the font, indicate which
features are present in the font for the selected script/language,
and expand the default specimen to cover latin, cyrillic and
greek.
Its very easy to get extra references to the NativeDialog so that
when you release your last reference any visible dialog is not
hidden. We handle this by adding a destroy method similar to how
you destroy regular toplevels.
Use the common automake module from the previous commit in the
Makefile.am's, which means that the Makefile.am's in gdk/ and gtk/ can be
cleaned up as a result. As a side effect, the property sheet that is used
to "install" the build results and headers can now be generated in terms of
the listing of headers to copy during 'make dist', where we can acquire
most of the list of headers to "install", so that we can largely avoid the
situation where the property sheet files are not updated in time for this,
causing missing headers when this build of GTK+ is being used.
Also use the Visual Studio Project file generation for the following
projects:
gtk3-demo
gtk3-demo-application
gtk3-icon-browser
gdk-win32
gdk-broadway
gail-util
So that the maintenace of these project files can be simplified as well.

Add a --run option which takes the name of an example and
launches it. Also add a --autoquit option which can be used
to quit after a given number of seconds.
