If a window is configured with a fixed size (it's tiled, maximized, or
fullscreen), ignore any resize call that doesn't respect this. The set
size will instead be saved, when appropriate, so that the new size is
used when e.g. unmaximizing.
This makes it possible to call 'gtk_window_resize()' while the window is
maximized, without the window actually changing size until it's
unmaximized. Changing size to a non-maximized size is a violation of the
xdg-shell protocol.
An application may want to set a fallback size of a window while still
mapping maximized. This is done by calling gtk_window_resize() before
gtk_window_maximize() and before gtk_window_show(). When the window is
mapped, it should have a maximized size, and if it eventually is
unmaximized, it should fall back to the size from the earlier
gtk_window_resize() call.
What happens before this commit is that the initial window size ends up
respecting the first gtk_window_resize() dimensions, and not the window
dimension configured by the Wayland display server (i.e. maximized
dimensions).
Fix this by postponing any configure events until we received our
configuration from the display server. If we got one with a fixed size
(e.g. we're maximized, tiled etc), we use that, otherwise we look at the
one that was previously configured by gtk which corresponds to the
"preferred" size when not being maximized.
This fixes Firefox being started in a maximized state when using the
Wayland backend.

On Wayland, opening and closing a `GdkDisplay` generates a coupe of
warnings at runtime:
```
GLib-GObject-WARNING **:
invalid cast from 'GdkWindowImplWayland' to 'GdkWindow'
GLib-GObject-WARNING **:
invalid cast from 'GdkWaylandWindow' to 'GdkWindowImplWayland'
```
This is from `gdk_window_impl_wayland_finalize()` which tries to cast
the given GObject to a `GdkWindow` while it's a `GdkWindowImplWayland`.
Use the correct type casting of objects to avoid the warnings.
If a client issues a `move_resize()` request while the window is
maximized or fullscreen, update the saved size for when it will be
unmaximized/unfullscreened

This is a backport of the GdkProfiler from master. It does not include
the pixel bandwidth numbers that come from gdkdrawcontext.c since there
does not seem to be an analog in 3.x.
Additionally, this implements the recent changes for SYsprof's D-Bus
profiler API which adds a Capabilities property and an options hash-table
to the D-Bus interface for forward portability.
The event received in `gdk_wayland_window_show_window_menu()` can
come from widgets with a GdkWindow. In those cases the coordinates
are relative to the widget, not the root window.
This results in a misplaced window menu.
Properly calculate the coordinates by iterating to the toplevel
window as suggested by Carlos Garnacho.

This uses the gtk_surface1.request_focus request added in gtk-shell v3,
the given startup ID may be used by the compositor in order to determine
when was the request started, and whether user input happened in between.

If the size was constrained by the xdg_positioner mechanisms, we handle
the resize by resizing the popup window. What we shouldn't do is
hide/show the popup window so avoid that.
Suggested by Garnacho. Hopefully fixes#1349.
Note: I'm riskily committing this via web UI not because I'm lazy
(though I am :) but because I'm seeing a weird host key when I try to
push or pull from GitLab.
Let's just use the fact that a window was mapped as a subsurface to
remap it above another transient parent instead of relying on the more
complicated 'should-map-as-subsurface' helper function.
The enum is duplicated in the spec for the manager and the decoration
object. We should be using the right ones. In practice they have the
same value, so this bug didn't cause any issues.
The wl_surface is destroyed and recreated when the window is
mapped/unmapped. As we have a new wl_surface we need to create a new
server_decoration object for that surface.
According to the spec compositors were to assume surfaces are CSD until
told otherwise. This means we need to send
org_kde_kwin_server_decoration_request_mode in both cases.
This fixes libreoffice under kwin, which would remove it's own headers
as per the manager's request but not inform kwin leaving it in the even
more broken state of having none.
The shortcuts inhibitors hash table is created when we create a
GdkWaylandWindow implementation for a GdkWindow, and it's destroyed once
we finalize the instance. The fake "root" window we create for the
Wayland display does not have a backing native window, so the shortcuts
inhibitors hash table is set to NULL; this causes a critical error
message when calling g_hash_table_destroy() on it. The finalization of
the root window happens when we close a display connection.
We should use g_clear_pointer(), instead, as it's NULL safe.
Without this change, the displayclose test fails, as all warnings are
considered fatal.
The stable xdg_shell port (5c8bb51a) introduced an error in
gdk_wayland_window_set_geometry_hints which would set the minimum size
to the maximum size, if provided.
This resulted in various wxWidgets apps (FileZilla, Audacity, Veracrypt)
crashing because they attempted to allocate a ginormous surface.
Fixes#157.
If a window is unmapped by the client while gdk is processing updates,
(for example Firefox un-mapping its window on Expose events), the
windowing backend resources might be lost (for example with Wayland)
which can cause a crash in end_paint().
Make sure we drop the cairo surfaces as well when hiding the surface,
that will avoid the crash in gdk_window_impl_wayland_end_paint() when
trying to attach the staging cairo surface to a released wl_surface,
these will be recreated when needed when the surface becomes visible
again and there is no need to keep such buffers around for a surface
which is not visible anyway.

This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

In order to map a window with the correct initial parent-child
relationship when a modal dialog is set up to be a child of an imported
foreign window, the relationship must be set up before the window is
mapped.
In order to do this, if a window is not yet mapped, postpone the
relationship setup until when the window is eventually mapped.

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.

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.

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.

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.

begin_resize_drag() and begin_move_drag() check for xdg_surface being

xdg_toplevel being non-null instead.

When an event is received while a tooltip is showing, the GtkTooltip's
event handling code can end up calling gdk_window_set_transient_for()
from gtk_tooltip_set_last_window().
The Wayland GDK backend will try to automatically create a subsurface
in gdk_wayland_window_set_transient_for() but if the parent surface is
gone meanwhile, this will will cause a crash when trying to create a
subsurface from a parent with a null surface.
Checking for the parent is not sufficient, we ought to check for the
parent surface as well to avoid the crash.

Applications can specify the type hint as utility even on toplevel
windows.
When that toplevel is also marked as a transient for another window,
GDK Wayland backend would translate that as an xdg_popup which is not
appropriate.
While utility temp windows should remain mapped as subsurfaces (such as
the ones used by treeviews), regular windows should not translate as
neither a subsurface nor an xdg_popup.

Allow getting the same export handle multiple times by calling
gdk_wayland_window_export_handle() multiple times. For each time
export() is called, a unexport() must be called to unexport.
When the window is already exported, the exported callback is called
via a idle handler. If there are multiple export() calls, they are
invoked in order either when the handle is received by the display
server, or when the idle callback is invoked.
Calling unexport() will not affect future invokations of the exported
callback, unless all export() calls have their unexport() call count
matched.
