gdk_wayland_window_attach_image() is normally called from
gdk_window_end_paint() to notify the compositor of newly staged drawing.
If any of the drawing code inadvertently dispatches the wayland event
loop (for instance with a gdk_flush() call), then it's possible that by
the time gdk_window_end_paint() is called, the staged drawing is already
destroyed.
This commit bypasses the attach_image call in scenarios where the staged
drawing is prematurely dropped.

These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
xdg_shell v6 allows grabless popups, whose behavior is not that
different from override redirect windows with no grab to take
keyboard input (and pointer events outside).
This means we can relax the requirement to have a grab before
creating an xdg_popup. The warning is still useful to have so
people stop relying on gdk_window_show();gdk_device_grab() being
an ok pattern to popup a window, it's been moved to wayland
implementation of gdk_device_grab() instead, so we warn if trying
to grab a GDK_WINDOW_TEMP window that's already visible.

Opaque region, margin and input region were only being synced when a cairo
paint happened. That caused GL paints to sometimes end up with bad state.
Move calls to sync state to gdk_window_impl_wayland_end_paint.

Setting the shadow width earlier as done with commit 4cb1b96 to address
bug 771561 proved to cause unexpected side effects on size_allocate
signal propagation.
As the window is sized correctly earlier, the size_allocate signal is
not emitted again in gtk_widget_size_allocate_with_baseline() which
prevents clutter-gtk from relocating its child widget correctly.
To avoid this issue, revert commit 4cb1b96 but make sure the values
passed as min and max size is never negative in Wayland as this is a
protocol error.
With this, the min/max size will be wrong for a short amount of time,
during the state transition, until the shadow width is updated from
gdk_window_set_shadow_width().
This approach is much safer and less intrusive than changing the
size_allocate logic in gtk.
This reverts commit 4cb1b9645e.

A popup may have moved and resized when configured. Make sure every
layer knows about this and call gdk_window_move_resize() with the
configured dimension and position. This won't actually move the
window, but might resize it.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
The result of move_to_rect, received from the xdg_popup.configure
event, needs to be translated to the correct coordinate space; that is
from real parent window geometry to coordinates relative to the gdk
window set as transient-for.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
Use a helper to translate a coordinate from non-real GdkWindow parent
to window geometry coordinate space of the real GdkWindow parent,
meaning the coordinate space of the GdkWindow of the parent used as a
xdg_popup parent where (0, 0) is inside of the shadow margin.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
When using the dynamic positioner (i.e. positioning from move_to_rect)
we can always rely on having a proper transient-for to position
relative to, so lets drop the ignored parameter.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
Move the code used for calculating the result of move_to_rect
(final_rect, flipped_rect etc) closer to the other move_to_rect
functions (i.e. next to create_dynamic_positioner), and let the
xdg_popup configure handler just call the calculation function.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
If an application umaps the toplevel from its popup callback, this can
lead to a protocol error.
Make sure we mark popup parent and use that to check if their parent is
the toplevel being unmapped in which case we shall unmap the popup first
to avoid the protocol error.
Bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=770906
When a popup is mapped but will not be the top most popup (for example
the parent is not the current top most popup, or if there already is a
popup mapped but the parent is a toplevel), warn and ignore it instead
of continuing, as continuing would be a protocol violation.
https://bugzilla.gnome.org/show_bug.cgi?id=770745
Add an API that enables an application to, given an exported window
handle, set its own window as a transient of the window associated with
the exported window handle.

Only set input, opaque and window geometry regions once per commit.
They are double buffered anyway, so the last one would only take effect
either way; this way reading protocol logs are much more pleasent.
https://bugzilla.gnome.org/show_bug.cgi?id=769937
At the time of move_to_rect() is called, not all state may have been set
up on the impl gdk window, causing the position to sometimes be
slightly offset due to drap shadow margins. For now, work around this
by postponing the processing of the move_to_rect() parameters until
showing, when its more likely that all state (such as shadow margin)
has been set correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
The position of each transient-of will be in fake-root coordinate
space; thus we should not accumulate all the positions making it an
offset; each window is already in fake root coordinate space.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
When using the set transient-for as a popup parent, fetch the effective
toplevel instead, otherwise we will position against the wrong
coordinate.

This matches the behaviour of Mutter, Metacity and traditional X11
window managers on the window manager side, and is what we want
for at least gnome-terminal. I can't think of any reason why we'd
want incremental resize in any other tiled window.

A wl_buffer has a max size of 4096 bytes, of which 8 are needed for the
header and another 4 for the string argument length (in this case), so
make sure the we only save the first 4083 bytes that are still valid
UTF8.

xdg-shell allows desktop environments to extend the list of states
within a given range.
Use this possibility to add a new state for tiled so that gtk+ can
benefit from this.

In Wayland, surfaces get an enter/leave notification each time they
enter or leave an output.
Add an API to GdkWaylandWindow to retrieve the output the window has
last entered.

Use of g_signal_handlers_disconnect_by_func() needs to do more work than
necessary to find all the matching handlers. Instead, just hold on to the
signal identifier and remove it directly so we hit the fast path.
Not terribly ground breaking in terms of performance gains, but its done
enough to be worthwhile.
https://bugzilla.gnome.org/show_bug.cgi?id=766049
Don't track all orphaned dialogs globally, as mixing them up with each
other would in most cases trigger errors when we try to pass bogus
values to Wayland requests.

The naming of pointers to GdkWaylandDisplay's were inconsistent.
Running the following commands in gtk+/gdk/wayland illustrate the
inconsistency:
$ grep -r '\<display_wayland\>' *.[ch] | wc -l
195
$ grep -r '\<wayland_display\>' *.[ch] | wc -l
81
This patch renames all occurrences of "wayland_display" to
"display_wayland". This is also consistent with naming in the X11
backend. A couple of whitespace changes were done as well in places
where the rename was already done, that added line breaks to long lines
that stood out.

gnome-control-center is calling gtk_window_resize() on configure-event
signals which leads to a busy loop.
Avoids such a busy loop by not re-configuring a window with the same
size, unless this is coming from and xdg-shell configure.
bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=764374
If the configure-event gives us the same size as we had before,
which is common for animation resizes, then try to keep the
existing buffer around. This saves us a memfd_create() syscall
on every frame.
