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.

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.

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
not null, but those apply on xdg_toplevel so they should check for
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.

Use the gravity enum values when converting to gravity. It doesn't fix
anything, since the enum values were identical, but it makes a coverity
warning go away.

When resizing an xdg_popup immediately after the initial mapping, there
is a race condition between the client and the compositor which is
processing the initial size given by the xdg_positioner, leading to the
xdg_popup to be eventually of the wrong size.
Only way to make sure the size is correct in that case is to hide and
show the window again. Considering this occurs before the initial
configure is processed, it should not be noticeable.

Clamping the anchor values as introduced in commit 9a5ffcd to fix bug
777176 breaks menu positioning.
By keeping the anchors rectangle size greater than zero, we end up
deducting some positive value from the original position, so there is no
need to clamp() actually, keeping the values positive is enough and
avoids the issue with menu positioning on the menubar.
An additional benefit is to make the code a lot simpler.

Currently hiding destroys the wl_surface and all related interfaces,
(including the gtk_surface1) so the next time the GdkWindow is mapped,
we don't bother to set the DBus properties. Toggle the check off so
it's actually issued again after the GdkWindow gets a gtk_surface1.

This is how windows are meant to be hidden as per the wayland
protocol, there's no need to destroy the xdg_surface and other
interfaces.
Also, rename gdk_wayland_window_hide_surface() to clear_surface(),
as that's what it does.

Passing a rectangle with zero width or height to xdg_shell-v6
set_anchor_rect() will cause a protocol error and terminate the client,
as with gedit when pressing the Win key.
Reason for this is because the rectangle used to set the anchor comes
from gtk_text_layout_get_iter_location() which uses the pango layout
width/height, which can be empty if there is not character at the given
location.
Make sure we don't use 0 as width or height as an anchor rectangle to
avoid the protocol error, and compensate the logical position of the
given rectangle if the size is changed, so that the actual position
remains as expected by the client.

When a subsurface is used as a parent of a popup, GDK needs to traverse
up to the transient-for as the next parent, to properly find the parent
used by the popup positioner. This is because the parent of a popup
must always either be an xdg_popup or an xdg_surface, but traversing
the "parent" (in GDK terms) upwards from a subsurface will end up on
the fake root window before we hit the actual parent (in Wayland terms).
https://bugzilla.gnome.org/show_bug.cgi?id=776225
For subsurfaces, the new state which includes the input shape is not
applied by the compositor if the subsurface is in effective synchronous
mode.
So we need to apply the input shape once parent surface is in effective
desynchronized mode, which is when it's committed, otherwise the input
shape may never be applied if the widget is not using being_paint() /
end_paint() to draw on its subsurface, like clutter does.
We do that only for empty input shape as those won't need update when
the subsurface is resized, for all other non-empty input shape, the
client still has to use begin_paint()/end_paint() for the input shape to
be applied.
https://bugzilla.gnome.org/show_bug.cgi?id=774534
Now that subsurfaces can be created as child of another GdkWindow (and
not just the root window), they must be placed according to the location
of their parent, i.e. the abs_x/abs_y must be updated and taken into
account when placing and moving subsurfaces under Wayland.
