We can't destroy buffers if they're in-use by the compositor. Well,
technically we can, but that is considered undefined by Wayland and
mutter won't cope with it very well -- it simply kills the client.
To solve this, we need to delay the destroy operation until the
compositor tells us that it's released the buffer. To do this, hold
an extra ref on the cairo surface as long as the surface is in-use
by the compositor.
This prevents warnings like
(gtk3-demo:14948): Gdk-CRITICAL **: _gdk_frame_clock_thaw: assertion 'GDK_IS_FRAME_CLOCK (clock)' failed
(gtk3-demo:14948): Gdk-CRITICAL **: gdk_frame_clock_get_timings: assertion 'GDK_IS_FRAME_CLOCK (frame_clock)' failed
We need to do this, as the compositor might have already sent us a frame
event, in-flight, at the same time we destroy our window. In this case, we'll
receive the then-in-flight "done" event, and then warn as we try to look
up the frame clock on a destroyed window.
We may get a NULL region passed to the backend, which means
'nothing is opaque'. In that case, don't crash, but pass
the information on to the compositor.

The surface is destroyed when we hide a window, but
gdk_window_set_opaque_region can be called before the window is
shown again, so we need to ensure the surface exits.

If the compositor supports the gtk-shell interface, use it to
export the application ID, dbus name and paths that can be used
for the application menu.

Many parts of GTK+ assume that all windows have a cairo surface
assoicated with them. This change provides a logically 1x1 cairo surface
(respecting scale) for the root window.

If we bind to a global with an higher version than implemented, or
we make requests that appeared in a later version, we would get
fatal wayland errors.

Ths allows the retrieval of the wl_surface before the window is shown.
The surface is still created in the original places since the surface
and shell surface is destroyed when the surface is programmatically
hidden.
We've long had double precision mouse coordinates on wayland (e.g.
when rotating a window) but with the new scaling we even have it on
X (and, its also in Xinput2), so convert all the internal mouse/device
position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.
We track the list of outputs each window is on, and set the
scale to the largest scale value of the outputs. Any time the scale
changes we also emit a configure event.
If we got the release event for the last buffer then we're
fine with writing directly to the window surface, as wayland
will not be looing at it. This saves us from allocating
and copying more data.
There is currently no Wayland protocol for providing presentation
timestamps or hints about when drawing will be presented onscreen.
However, by assuming the straightforward algorithm used by the
DRM backend to Weston, we can reverse engineer the right values.

Combine duplicate code for creating and destroying surfaces.
To make the operation of the destroy() operation more obvious, the
destruction of the (fake) root window at display dispose time is
changed to not be a "foreign" destroy.

Use wl_surface_frame() to get notification when the compositor paints
a frame, and use this to throttle drawing to the compositor's refresh
cycle.

Lazily creating the cairo surface that backs a window when we
first paint to it means that the call to
gdk_wayland_window_attach_image() in
gdk_wayland_window_process_updates_recurse() wasn't working the
first time a window was painted.

When exposing an area, we were individually damaging and committing
each rectangle, *before* drawing. Surprisingly, this almost worked.
Order things right and only commit once.

Allow to set a GdkWindow to use a custom surface instead of a
wl_shell_surface. It allows to register the surface as a custom type
with some Wayland interface.

Use separate fields for saving the window dimensions prior to fullscreening
and maximisation. Then use those fields to restore the window dimensions from.
With recent changes in attach semantics, we always need to attach before
committing. Without this changes to the window contents to not get reflected
in the content of the surface.

Deprecate gdk_window_enable_synchronized_configure() and
gdk_window_configure_done() and make them no-ops. Implement the
handling of _NET_WM_SYNC_REQUEST in terms of the frame cycle -
we know that all processing will be finished in the next frame
cycle after the ConfigureNotify is received.
Allows to access Wayland specific window information like wl_surface and
wl_shell_surface.
Add gdk_wayland_window_get_wl_surface for getting the Wayland wl_surface
and gdk_wayland_window_get_wl_shell_surface for getting the Wayland
wl_shell_surface.
If we don't have a wl_seat - because a grab hasn't been initialised by GTK+
then fallback to making the shell surface transient to the parent rather than
a popup surface.
This replaces the wl_input_device with wl_pointer, wl_keyboard, wl_touch all
tied together under a wl_seat.
This is quite a radical change in protocol and for now keyboard handling is
disabled.
This allows combo box popup windows to appear in the correct place. This is a
workaround emulating root coordinates by calculating the offset for a chain
of windows that that are relative to each other.
Once we've made them popup windows we must also implement the popup_done event
handler on the shell surface listener. The best we can currently do is to hide
the window. This will then signal up to GTK which could then deactivate the
appropriate menu (see https://bugzilla.gnome.org/show_bug.cgi?id=670881)
This allows us to get the device if we need to make the window a popup. This
relies on the side effect that GTK calls into GDK to take a grab before the
popup window is shown.
Callers of this function were passing in -1, -1 for the width and height if
they just wanted the window moving - rather than the size changing. We need to
respect that behaviour and don't try and set the width/height to those
dimensions.
Now pop-up windows (ala combo-boxes) work!
When we receive a configure event from Wayland telling us to resize our
surface we check against the geometry constraints for the window to ensure we
do not resize below the minimum and maximum limits.
Now that grab and ungrab vfuncs are implemented on GdkDevice then we can use
gdk_device_ungrab to break the implicit grab created by the button press that
triggered the resize and move.
An implicit grab is created inside GTK+ when the button is pressed down on a
window. The semantics of wl_shell_surface_resize means that you don't get a
corresponding release event that would ordinarily break the implicit grab. So
we must do it as part of the resize request.
Previously all the commands that acted on the shell took the surface that was
to be acted on as parameter. Now we retrieve an object from the shell that
represents its state for the surface. With that wl_shell_surface object we can
then call methods on that.

This will trigger a repaint of the window, but it may be more efficient
to just copy back the old surface contents and let gtk+ just update the
changed parts.
