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.
This uses the same function for dumping CSS nodes and styles
as the CSS node test. It can be used to test aspects of inheritance
and matching, as well as initial values.
No actual tests yet.
Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.

GTK cannot depend on libcanberra-gtk which depends on GTK. This causes
a circular dependency and is especially neat if installed GTK is
different enough from uninstalled GTK.
"Add" Visual Studio 2015 projects by what we did before: Copy the Visual
Studio 2010 project files and replace the items in there as needed, as
the formats of the 2010 and 2015 projects are largely the same.
We need to rename the projects so that when these projects are added
into an all-in-one solution file that will build the GTK+ 2/3 stack,
the names of the projects will not collide with the GTK+-2.x ones,
especially as GTK+-2.x and GTK+-3.x are done to co-exist on the same
system. This is due to the case that the MSVC projects are directly
carried over from the GTK+-2.x ones and was then updated for 3.x.
We still need to update the GUIDs of the projects, so that they won't
conflict with the GTK+-2.x ones.
Use a separate G_ENABLE_CONSISTENCY_CHECKS define to guard internal
consistency checks that are applied unconditionally if they are enabled,
such as the widget invariants checking. Interactive debug spew that can
be triggered at runtime with the GTK_DEBUG environment variable is still
guarded by the G_ENABLE_DEBUG define.
The mapping from enable-debug levels to defines is as follows:
yes: G_ENABLE_DEBUG G_ENABLE_CONSISTENCY_CHECKS
minimum: G_ENABLE_DEBUG G_DISABLE_CAST_CHECKS
no: G_DISABLE_CAST_CHECKS G_DISABLE_ASSERT G_DISABLE_CHECKS
GTK+ now uses pango_attr_foreground_alpha_new, pango_attr_background_alpha_new,
PANGO_ATTR_FOREGROUND_ALPHA, PANGO_ATTR_BACKGROUND_ALPHA,
pango_renderer_set_alpha, pango_renderer_get_alpha, which were all added
after 1.37.2.
I invadvertendly introduced a dependency on a recent GLib recently,
by cherry-picking a fix that used new GLib API. This commit will
help catching such errors before release, by using the versioned
deprecation machinery to turn such events into build-time
warnings.
This patch introduces support for using the newly introduced
monitor objects in the XRandR protocol. These objects are meant
to be used to denote a set of rectangles representing a logical
monitor, and are used to hide details like monitor tiling and
virtual gpu outputs.
This uses the new objects instead of crtc/outputs objects when
they are available to create the monitor lists. X server 1.18
is required on the server side for randr 1.5.

It's now needed by gtk-launch, so it's just the case to enable it for all the
builds except the win32 one, instead of adding it for every unix backend.

Requires Vista and newer.
* Create surfaces with cairo_win32_surface_create_with_format
* Provide an rgba visual that can be distinguished from the system visual
* Make rgba visual the best available visual
* Enable alpha-transparency for all windows that we control
* Check for appropriate cairo capabilities at configure time
(W32 - 1.14.3 newer than 2015-04-14; others - 1.14.0)
* Check for composition support before enabling CSDs
* Re-enable transparency on WM_DWMCOMPOSITIONCHANGED
Windows that were created while composition was enabled and that were CSDed
as a result and will look ugly (thick black borders or no borders at all) once
composition is disabled.
If composition is enabled afterwards, they will return back to normal.
This happens, for example, when RDP session is opened to a desktop where a GTK
application is running. For W7/Vista windows will only re-gain transparency after
the RDP session is closed. For W8 transparency will only be gone momentarily.
Windows that were created while composition was disabled will not be CSDed
automatically and will use SSD (WM decorations), while windows that are CSDed
manually will get a thin square border.
If composition is enabled afterwards, these windows will not change.
This is most noticeable for system menus (popup menus are often generated
on the fly, system menus are created once) and some dialogues (About dialogue,
for example).

isatty() on MSYS2 returns non-zero if the fd is stdout and is redirected
to /dev/null. That lets xgettext to produce colorized output and leads
to an assertion failure during terminal type detection.
Although the problem should be fixed in MSYS2, isatty() could behave
wrongly in many ways on Windows. Since gtk+ doesn't need colorized
output, it would be safer to bypass the terminal dependent code.

The current GdkScreen->is_composited() is a stub as we were having Windows
XP being supported, which does not support Desktop Window Manager (DWM),
which is used by Windows for composition.
Windows Vista and later support DWM, and it is always enabled on Windows 8/
Server 2012 and later.
Please note that as we are dropping XP support in this cycle, this is the
commit that would say goodbye to Windows XP support for GTK+-3.x, by
linking directly to dwmapi.dll. This means, we only check whether we are
on Windows 8 or Server 2012 (or later) to see whether we unconditionally
have composition enabled.
