Instead of using a boolean to indicate a modal operation being in progress,
use a set of flags, and allow these to be set and unset independently.
Specifically, this allows WM_CAPTURECHANGED handler to only act when a drag-move or
drag-resize modal operation is in progress, and ignore DND (which can also cause
WM_CAPTURECHANGED to be posted). This avoids a crash due to assertion failure when
OLE2 DND code tries to end a modal operation that was already ended by the WM_CAPTURECHANGED
handler.

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that GdkWin32Display::gl_hdc becomes out-of-date and so the HDC that the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.

Otherwise, builds that include the Wayland backend fail.

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.

This state flag is used in several places in GTK+, for example to
ignore RESIZE_INC hints if tiled. Setting it is also necessary for
backwards compatibility with applications that changed their behaviour
when tiled, such as GNOME Terminal and its MATE fork.

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.

Commit c415bef5de introduced support for the new _GTK_EDGE_CONSTRAINTS
atom. If the compositor supports that atom, however, we were always
setting the tiled state, even if no actual tiling information is
available, where the correct action is to completely remove any traces
of the tiled state.
Fix that by correctly removing the tiled state when compositor supports
_GTK_EDGE_CONSTRAINTS Xatom.

Following the previous patch, where edge constraints support
was added to the Wayland backend, this patch introduces the
necessary code to handle the _GTK_EDGE_CONSTRAINTS atom from
X11 backend.

Now that GTK windows have the ability to properly handle
per-edge tiling constraints, this patch extends GTK's
internal Wayland protocol to have a proper enum with the
relevant edge data.
Once this approach is validated, we can think of upstreaming
this work as an official Wayland protocol extension.
https://bugzilla.gnome.org/show_bug.cgi?id=783669
These states will be consumed by GtkWindow in order to
have better edge management on tiling situations. Their
values are supplied by the compositor, and will be send
through and X11 Atom or a Wayland protocol extension.

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.

Under X, we were not setting the right drag cursor initially,
because at current_action == action == 0, initially. Fix this
by explicitly using the right cursor when grabbing.
Commit 1d0fad3 revealed that there were some assumptions made that were
actually to compensate for the bug fixed by that commit, so we need to
remove those assumptions as they would result in AerSnap to not work
properly on HiDPI screens.
Also re-do how we set the x and y positions of our GdkWindow, so that we
are more consistent across the board when we go between a GDK window
coordinate and a Windows API window cooredinate.
This would also simplify the code a bit.

This property contains 5 integers, of which the last 2 respectively
contain the tool serial number and tool ID. We were only extracting the
first so far, but GdkDeviceTool also has API getters for the latter,
which remained 0.

This adds support for the shortcut inhibitor protocol in gdk/wayland
backend.
A shortcut inhibitor request is issued from the gdk wayland backend for
both the older, deprecated API gdk_device_grab() and the new gdk seat
API gdk_seat_grab(), but only if the requested capability is for the
keyboard only.

This check must be done explicitly on Wayland as the master device for
tablet tools differ from the Core Pointer. This ensures that whenever a
tablet tool is inside a window and the cursor is programmatically changed,
it will be visually updated too.

Even though no Wacom tablet puck has a smooth-scrolling wheel, both event

If a tablet device is used to perform actions like window moving or resizing,
GTK must provide the correct implicit grab serial number over Wayland to Mutter
in order for the action to succeed. This commit adds tablet support to the
implicit serial getters.

If a bad behaving application tries to make the window/display beep too
often, throttle the beep requests so that we don't end up filling the
Wayland socket queue.
The throttle is set to 50 beeps per second, which far more beeps than
will ever make any sense from a user experience point of view, but will
avoid terminating due to an excessive amount of requests.
