We create various windows during the initial creation of display
objects, which causes some bootstrapping issues when we try to
find the default screen to get its root window. To work around this,
pass the display object into gdk_window_new.
This is not an API change, since gdk_window_new is no longer public API.
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.

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.

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).

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.

We're not currently using this, and dropping it allows us to loose
a bunch of code which leads us towards the goal of having GdkWindow
only for toplevels (and reparenting makes not sense for toplevels).
We can't really support these on e.g. wayland anyway, and we're trying
to get rid of subwindow at totally in the long term, so lets drop this.
It allows us to drop a lot of complexity.
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.

I read the code as if (use_gl) instead of if (!use_gl) and commented it
out in bddfd7bb41. That broke drawing on
Wayland without OpenGL completely.
Whoops.
Now it's back.
No visible changes as GL rendering is disabled at the moment.
What was done:
1. Move window->invalidate_for_new_frame to glcontext->begin_frame
This moves the code to where it is used (the GLContext) and prepares it
for being called where it is used when actually beginning to draw the
frame.
2. Get rid of buffer-age usage
We want to let the application render directly to the backbuffer.
Because of that, we cannot make any assumptions about the contents the
application renders outside the clip area.
In particular GskGLRenderer renders random stuff there but not actual
contents.
3. Pass the actual GL context
Previously, we passed the shared context to end_frame, now we pass the
actual GL context that the application uses for rendering. This is so
that the vfuncs could prepare the actual contexts for rendering (they
don't currently).
4. Simplify the code
The previous code set up the final drawing method in begin_frame.
Instead, we now just ensure the clip area is something we can render
and decide on the actual method in end_frame.
This is both more robust (we can change the clip area in between if we
want to) and less code.
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 int
account when placing and moving subsurfaces under Wayland.

This can be triggered on workspace switches, and on hidpi results in
the scale factor being reset to 1 while the window is not in the
current workspace.

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.
