Like the X11 and Wayland backends, re-work how the cursors are being
handled. So, we use a hash table to cache up the HCURSORS that we
create along the way.
We still need to cache up the icon/cursor themes since this is something
that is not part of Windows but was added on to support icon/cursor themes
such as Adwaita on Windows, but should be in-line with what is going on in
GdkCursor.
Also, remove the _gdk_grab_cursor global variable in gdkprivate-win32.h,
and replace it with another variable in the GdkWin32Display structure,
to make things cleaner in the process.

We must reset the image delay when stopping the timeout,
otherwise the code setting it up thinks it is still running.
This fixes cursor animation only working for the very first
enter of a widget with an animated cursor, as seen in the
cursors example in gtk4-demo.
and gdk_texture_new_from_resource().
While doing set, turn all GDK_AVAILABLE_IN_3_90 into
GDK_AVAILABLE_IN_3_94 because that's now true after the renaming.
Since on Windows we need to use a good amount of temporary GL contexts,
we need to switch back to the original GL contexts we were using when
we are done with the temporary GL contexts, otherwise multi-GL windows
will cause confusions causing display artifacts and crashes.
Also, use the GdkWin32GLContext::gl_hdc consistently throughout
the code and remove the GdkWin32Display::gl_hdc as Lukas K pointed out
that GdkWin32Display::gl_hdc becomes out-of-date and so the HDC that the
GL context is bound to becomes incorrect in sceanarios using multiple
windows with GtkGLArea/GdkGLArea items (which would cause the artifacts in
programs that use multiple windows with GtkGLArea/GdkGLArea items, and it
turns out that GdkWin32Display::gl_hdc is actually not necessary to help
keep track of the HDCs we use for our GL contexts.
This will also fix on Windows with GDK_GL=always, or when GSK's gl
renderer is used.
Partly based on patch from Lukas K <lu@0x83.eu>

Move the leftovers from the removals to use the current APIs, to fix the
build. Also for gdk_device_virtual_set_window_cursor(), only do
something when a valid GdkCursor is passed in here.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
Instead of creating a GdkX11Cursor, create GdkCursors. Cache the XCursor
in a hash table instead.
Also, make use of the new fallback mechanism for fallback code: Make
sure to provide cursors for the names that are guaranteed to exist, but
do not do bad attempts at displaying texture surfaces.
Black/White/transparent is not a replacement for those.
Stop wrapping the xsettings manager window in a foreign
window. This means that we cannot use the gdk window filter
APIs anymore, so just do the filtering in a non-generic
way.
The preferred api to create cursors is by name, and the
GdkCursorType enumeration can directly trace its ancestry
to the horrible X cursor font. So lets stop using it.
gdk_display_get_default_screen is gone, but we still
have x11-specific screen apis that GTK+ is using, so
we need an alterative way to get the screen object.
GTK+ now uses the gtk-xft-dpi setting directly.
Note: this commit only fixes the backends that
currently provide this setting. The win32 and
Quartz backends still need to be fixed.
Drop the screen argument from gdk_dnd_find_window_for_screen
and rename the function to gdk_dnd_find_window. The screen
argument does not add anything here since the drag context
is already tied to the display. Update all backends, and
update all callers.
Implement GdkDisplay->get_setting() using the existing
_gdk_win32_screen_get_setting() and get rid of GdkScreen->get_setting()
as a result, to follow the changes in GDK.
Also, since we don't emit settings events in the Windows GDK backend,
but we acquire settings to print using GDK_SETTING, drop all references
related to GDK_SETTING since that is now removed. Update the debug
strings that are print out as a result
(gdk_screen_get_setting->gdk_display_get_setting).
https://bugzilla.gnome.org/show_bug.cgi?id=773299
We are not emitting these events anymore, so lets remove them
from the api. The GdkSettingAction enum is moved to xsettings-client.c
where its only use remains.
This commit adds gdk_display_get_setting and a ::setting-changed
signal, which will replace the settings event we use now. Note
that I've done away with the GdkSettingAction argument that the
event has, since we are not using it at all.
The code that checks for the proper size of the our swapchain
was not taking window scale fully into account. With this change,
setting the window scale to 2 in the inspector causes the window
to grow and rendering to be scaled up as expected, with Vulkan,
in the same way it already is with cairo.
Epoxy 1.4 has new ad hoc API that we can use to check whether GLX is
available on the current system.
If we didn't use this API, we'd have to manually dlopen libGL (or its
equivalent on different OSes) and check if it had GLX symbols; since
Epoxy already does all of this internally, we can simply ask it instead.

According to the documentation, gdk_monitor_get_geometry() reports the
monitor geometry in ”application pixels”, not in ”device pixels”,
meaning that the actual device resolution needs to be scaled down by the
scale factor of the output.
x11 backend does that downscaling, whereas Wayland backend did not,
causing a discrepancy depending on the backend used.

If the compositor prefers server-side decorations and the client doesn't
customize the title bar, we disable client-side decorations and let the
compositor know. Otherwise, we continue to use client-side decorations.

Under Wayland, an xdg_surface.configure with size 0x0 means it's up to
the client to set its size.
When transitioning from maximized state to un-maximized, the Wayland
compositor will send such an 0x0 configure so that the client can
restore its original size.
However, the original size was already constrained, so re-applying
size constrains can lead to a smaller size when using size increments.
Avoid this caveat by not applying size constrains when we are restoring
the original size.

We were unnecessarily spewing warnings when blank cursors
were getting a new scale set. Standardize on "none" as the
name for blank cursors, and avoid the warning.

Some clients (e.g. gnome-online-accounts) quickly unmap and map
a window. With some backends the backend surface will be replaced
causing the application to crash because the GL context is still
using the old surface. Clearing the GL context when a window is
withdrawn fixes this.
https://bugzilla.gnome.org/show_bug.cgi?id=789141
The list of surfaces passed into the function may be NULL, so don't try
to initialize the surfaces if it is so, to avoid a crash.
Also, remove the cast to GdkPixbuf* for getting surfaces->data, as we
are already using a cairo_surface_t*.

When building with G_DISABLE_ASSERT, the g_assert_not_reached()
statement won't do anything, and we're going to fall through, and the
compiler will emit a warning that we're not returning anything from a
function with a return value.
Add the necessary machinery into the Meson definition files so that we
can build for Windows.
Since we don't have Wayland or X support for our use case here, disable
them once we know that we are building for Windows, as they are
(otherwise) enabled by default, and enable the items that need to be
built for Windows builds.
Exclude gtk4-launch from Windows builds as that is something that
is not supported on Windows.
As we won't have gio-unix on Windows, and PangoFT2 is optional, don't use
fallbacks for them when we are on Windows (but do use fallbacks for
gio-win32, as it will be used).
Also, clean up meson.build a bit as we can just force-include
msvc_recommended_pragmas.h from GLib since we depend on GLib, and so we
can handle these warnings from msvc_recommended_pragmas.h instead.

This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
There is no guarantee that the gtk_surface won't be NULL,
and Wayland API does not safeguard against NULL, so we have
to do that ourselves here.
We were also mistakenly cheking for the surface version off
by one, fix that too by checking if the surface version is
equal or greater.
gdk_seat_default_grab() grabs POINTER_EVENTS if the capability is
GDK_SEAT_CAPABILITY_ALL_POINTING. But that enumerator is a union that
includes GDK_SEAT_CAPABILITY_TOUCH, but we never grabbed TOUCH_EVENTS,
an unused macro that was presumably created with this purpose in mind.
So, check which of the ALL_POINTING capabilities we have, and set the
right mask of POINTER_EVENTS and/or TOUCH_EVENTS as required.
As part of this, explicitly let TABLET_STYLUS take over pointer events,
as this is the intended behaviour and was the effective result before.
This should fix touch events being lost in migrating from Device.grab()
to Seat.grab(GDK_SEAT_CAPABILITY_ALL_POINTING), as found by Inkscape.
https://bugzilla.gnome.org/show_bug.cgi?id=781757
The behavior where a touchpoint takes over the pointer position is
really backend dependent. Since this went away from the generic code,
implement it here.
This was by all lights broken, and is basically an implementation detail
of the X11 backend since the pointer emulating touch just steals the pointer
cursor, so should be reimplemented there.
One used to point to the toplevel and the other to the client-side window
that the pointer pointed to. The latter was made to be like the former in
most places, so put those together, and fix the remaining cases where the
variable might not end up with a toplevel/native window.
This is not necessary now that there's no client-side windows to track.
The only removed piece that could make sense is emission of grab broken
events, but it's already an stretch since the semantics of those with
multi-touchpoint is unclear.
Anyhow, This should be fixed at the GTK level, while we let GDK deal with
seat/device level grabs.
GDK just needs to care about toplevels nowadays, which means these events
are already delivered from the windowing. We don't need to generate
intra-window crossing events ourselves.
Those should be interpreted by widget-local gestures, not guessed at a
high level with no notions of the specific context. Users will want
GtkGestureMultiPress to replace these events.
