DLL loading failures should not happen under normal circumstances, but
we should at least try not to crash and and print better diagnostic
messages if they do happen.
See #4610
Previously, we treated CapsLock and KanaLock as part of the global
keyboard state, much like NumLock and ScrollLock, rather than using
the supplied modifier mask. This was because GDK does not have a
modifier mask for KanaLock, only for CapsLock, so it would not have been
possible to properly support it.
However, this approach ended up causing problems, with certain keyboard
shortcuts not registering when capslock was active. This was first
observed in Inkscape [0] and appears to affect shortcuts consisting of a
single key (like 'a') with no additional modifiers (wheareas shortcuts
like 'ctrl+a' work).
So now we are using the supplied GDK_LOCK_MASK instead, and dropped
support for KanaLock, which we probably don't need anyway (since regular
text input should be handled by the IME input module -- the keymap is
mainly for shortcuts and keybindings, where you don't really want
KanaLock).

gdk_win32_keymap_get_entries_for_keycode() did not initialize n_entries,
which led to a wrong number of items being returned in some cases.

This will enable us to not confuse with the deprecated headers in
gtk/deprecated as those headers are also listed under deprecated_h_sources in
gtk/deprecated/Makefile.inc, when we include the makefile snippets in both
gdk/ and gtk/.
This makes the rest of the sources that are generated being put in GDK's build
directory for the Visual Studio projects, instead of being placed in GDK's
source subdir, so that:
* We can avoid polluting GDK's source tree.
* The Visual Studio builds won't interfere with the Meson builds.
Update the project files to look for the generated sources and headers in the
right places, as well as making the introspection builds look for the generated
sources as well.
Also remove the gtk3-gen-srcs property sheets and put the relevant parts in the
corresponding gtk3-build-defines property sheets, to clean things up a bit.
We now have a boolean setting that determines whether the high-contrast
theme should be used. Support it by automatically setting the existing
`gtk-theme-name` and `gtk-icon-theme-name` properties when enabled.
With that, it is no longer necessary to change the regular theme settings
for high-contrast, so toggling between high-contrast and a non-default
theme finally works reliably.
`gdk_quartz_display_get_monitor_at_window` crashes when it tries to access the NSWindow on
an offscreen window. The attribute `toplevel` of `impl` is uninitialized and
causes a segfault.
This partially fixes: https://gitlab.gnome.org/GNOME/gimp/-/issues/7608
Windows keymaps contain some bogus mappings, e.g. Ctrl+Backspace=Delete.
Previously, we correctly identified the key as Backspace, but the Ctrl
was still consumed, so the Ctrl+Backspace keybinding did not work.
gdk_win32_keymap_translate_keyboard_state erroneously used the active
group rather than the specified group, which caused shortcuts not to
work in Inkscape when using a Cyrillic layout.
This consolidates the check for the running CPU in one single location,
to make things a bit cleaner, as:
* We can make use of IsWow64Process2(), if available, to check both
whether we are running on an ARM64 CPU, and whether we are running as
a WOW64 process. This is also the function to use to properly check
whether we are running as a WOW64 process on ARM64 systems, as
IsWow64Process() does not work as we want on ARM64 systems.
* If we don't have IsWow64Process2() (which is absent from Windows prior
to Windows 10 1511, where ARM64 Windows is introduced), we can fall
back to IsWow64Process(), which will tell us whether we are running
as an WOW64 process (but clearly not on an ARM64 system).
Also clean up things a bit so that we can reduce reliance on global
variables.
The old code used repeated calls to `ToUnicodeEx` to populate
the translation table, which is slow and buggy. The new code
directly loads the layout driver DLLs from Windows.

When a selection request fails to be converted to the requested format in the
GTK layers, the wayland backend would miss bumping the machinery to handle
further pending selection requests. Fix this by reacting to
GdkDisplay::send_selection_notify with target=GDK_NONE (i.e. a failed
conversion as hinted from the upper layers) to do that.
This ensures the clipboard handling doesn't lock up in the following
scenarios:
- GTK returned with a mismatching type to the one requested
- GTK fails to convert to the requested type
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4340
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.
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"
MinGW-w64 CRT provides no 'hid.lib' file. Instead, it has 'libhid.a'
which can be linked with '-lhid' linker argument.
Also, we have to declare the '_LIBADD' variable and add 'LDADDS' to it,
or 'LDADDS' won't do anything for the build.
Note that gdk_monitor_get_geometry () returns DPI-scaled values,
while the screen offset should be unscaled, as scales are properties
of indivdual monitors.
An arithmetic operation involving a signed and an unsigned operand
of the same rank will have both operands converted to *unsigned*.
That's an issue if the signed operand actually has a negative value.
That was causing issues with the handling of monitor geometries that
had negative x / y positions.
Commit 68188fc948 introduces a workaround for clients that try to
change the size of a popup after it is created, but inadvertently
introduces an infinite loop of surface creation when the popup enters
two or more wl_outputs with different scales on creation.
This commit checks if the size actually changed before applying the
workaround and avoids the loop.
Gdk doesn't know the scale of output globals it didn't bind. This
keeps them from entering the output list and triggering erroneous
changes in surface scales.
