This is useful when clients use subsurfaces independently of GDK.
For example if a client creates a subsurface that covers a GdkWindow
entirely. If this subsurface is opaque, Wayland compositors may not
emit callbacks for the surface of the GdkWindow any more.
Adding the covering subsurface via this new API ensures the
GdkWindow will continue to update in this case.
These shadows cause a significant draw performance drop for maximized
windows. Disabling them increases the chances we can have faster scroll
performance of text.
There is some risk here for systems where they have a dock and you expect
the shadow to draw beneath that dock for transparency reasons.
Improve compose sequence handling:
- Show preedit for compose seqences
- Support sequences of up to 20 code points
- Warn when ignoring Compose file features
- Support compose sequences producing multiple characters
- Support hex escapes
This commit unsubscribes CUPS backend from a DBus
signal in idle when listening for new items on Avahi.
Since GDBus emits gathered signals in idle while
checking whether the signal has been unsubscribed
it could happen that a signal was not processed
because it was removed from hash table of
subscribed signals.
This caused the situation where printers advertised
on Avahi were not listed in CUPS backend sometimes.
We need those signals since this happens when switching
from a general subscription which listens to signals
for all Avahi services to a specific one which listens
to just _ipp._tcp and _ipps._tcp (chicken and egg problem).
This change extends set of Avahi advertised printers which
works with Gtk's CUPS print backend.
It creates a temporary queue (local printer) for each
Avahi printer in CUPS instead of accessing them directly
(via CUPS library).
This makes some printers work which did not work before and
also gives users more options to change in the print dialog.
This also changes naming of printers to be in accordance with CUPS.
It uses '_' instead of '-' and has hostname appended for CUPS remote
printers.
As the program executable name has 'update' in its filename,
gtk-update-icon-cache.exe is considered to be an installer program on 32-bit
Windows [1], which will cause the program to fail to run unless it is running
with elevated privileges (i.e. UAC).
Avoid this situation by embedding a manifest file into the final executable
that tells Windows that this is not a program that requires elevation.
Also make the autotools build files dist the new script and use the new script
to generate the manifest and rc files, instead of hardcoding the generating
bits in gtk/Makefile.am

Currently when GTK3 is compiled without G_ENABLE_DEBUG, the inspector
can't be opened with GTK_DEBUG=interactive because it doesn't parse
this env var without G_ENABLE_DEBUG.
Since the inspector is always good to have, this commit now always
parses the GTK_DEBUG env var but only keep the "interactive" flag if
G_ENABLE_DEBUG isn't defined.
Commit e6209de962 added some checks on TranslationEntry.valid in
order to figure out whether using the new font settings or the
old g-s-d ones. However that's only set in the non-sandboxed case.
This makes sandboxed applications fallback to the old (and also
non-existing with modern g-s-d) settings, possibly resulting in
ugly defaults being picked.
Fix this by also marking TranslationEntry elements as valid when
using the settings portal, precisely those entries that we are able
to read and match with our own table.
When destroying a wl_surface (e.g. when a window or menu is closed), the
surface may continue to exist in the compositor slightly longer than on
the client side. In that case, the surface can still receive input
events, which need to be ignored gracefully.
In particular, this prevents segfaulting on wl_surface_get_user_data()
in that situation.

It turns out that we must put Directory.Build.props in win32/vs10 and let
automake copy it over to win32/vs15/... so do that, and only dist the copy
in win32/vs15.
Update the NMake Makefiles used for generating the various sources be able to
cope with an ARM64 build environment, and update the project files, in
particular for Visual Studio 2017 (VisualStudioVersion 15.0) so that we can
pull in the system .lib's that were somehow excluded from the default list
on ARM64 builds.
Also, add a custom Directory.Build.props in win32/vs15 so that we do not
try to build with the Windows 8.1 SDK by defualt, which is not ready for ARM64
builds, but instead uses the appropriate Windows 10 SDK that supports this.
Update the README.win32 file to give people instructions on how ARM64 builds
can be carried out.
Look in the include/harfbuzz directory that is under the pre-defined prefix
directory, as Pango 1.44.x and later pulled in HarfBuzz headers for all builds
Intel OpenGL drivers have an issue where the results of a series of
glBlitFramebuffer() can delay updating the display, when we use GDK_GL=always,
which is manifested when attempting to enter text in text boxes.
This attempts to work around this issue by requiring a glFlush() call and a
retry to the same glBlitFramebuffer() calls to avoid delays in keystrokes when
using GDK_GL=always and when not using libANGLE OpenGL/ES emulation, when an
Intel OpenGL driver is being used.
Special thanks to Lukas K. for the analysis and coming up with a workaround,
which this patch builds upon.
Fixes issue 3487
fmin() is a function that is introduced with C99/C++11, so check for the
presence of it and provide a simple implementation for it if it does not
exist.
Also update the config.h.win32.in template accordingly, since this
function is provided on Visual Studio 2013 or later.
This way, we can enable the built binaries to print out diagnostic
messages as needed by the values we set via the envvar GDK_DEBUG.
The release configs of the Visual Studio project files follow the
settings of Meson's `debugoptimized` build settings.
