Whenever a MetaSurfaceActor is painted, update the list of what outputs
the surface is being drawed upon. Since we do this on paint, we
effectively avoids this whenever the surface is not drawn, for example
being minimized, on a non-active workspace, or simply outside of the
damage region of a frame.
DND icons and cursors are not affected by this patch, since they are not
drawn as MetaSurfaceActors. If a MetaSurfaceActor or a parent is cloned,
then we'll check the position of the original actor again when the clone is
drawn, which is slightly expensive, but harmless. If the MetaShapedTexture
instead is cloned, as GNOME Shell does in many cases, then these clones
will not cause duplicate position checks.

This will be useful in order to interact with drag dest surfaces in
its windowing-specific ways, although everything defaults to the
wayland vfuncs.

Add set_modal ond unset_modal to the gtk_surface interface. When a
surface is modal, the compositor can treat it differently from non-modal
dialogs, for example attach it to the parent window if any. There is
currently no changes to input device focus; it is up to the client to
ignore events to the parent surface that is wanted.
This bumps the gtk_shell version to 2.

Since the surface actor knows more about how it draws itself, instead of
pushing texture state (buffer and scale), input region and opaque region
from MetaWaylandSurface after having transformed into what the surface
actor expects, make the surface actor set its own state given what state
the Wayland surface is in.

It only contained a pointer to a wl_resource, which isn't much of
value. Just replace it with the wl_resource instead. Any future private
data should be handled by our future role system.
We assume in meta_window_wayland_move_resize that the next commit that
changes the geometry will always be for our next pending operation, so
if we have a move pending on a resize, the next commit will trigger the
move. This is, of course, fundamentally wrong.
We broke this assumption even more now that we don't fizzle out calls to
meta_window_move_resize_internal and now call it on every commit, which
means that a simple damage and then commit would complete a pending
move.
This was even broken by apps like weston-terminal, which, when clicking
on the maximize button, first redraws the terminal with the maximize
button state back on hover on press, and would only redraw when it got
the configure event with the coordinates.
To track the correct commit to apply the move for, we implement the
ack_configure request and ignore all move/resizes that happen before
that.
Right now, we actually fizzle out the entire move/resize if there's a
future pending configure we're waiting on.
Advertise the scale factor on the output and transform pointer and damage
events as well as input and opaque regions for clients
that scale up by themselves i.e use set_buffer_scale.
We do not scale any 'legacy' apps yet.

I was talking with other people and they became confused at the
term "double-buffered", since we were also talking about
double-buffering in general, e.g. swapping between two buffers.
Instead, we'll adapt the "pending state" nomenclature that we
already use for the field / variable names.
The make_toplevel / window_unmanaging interface has never made
a lot of sense to me. Replace it with set_window, which does
effectively the same thing.
It's still not perfect in the case of XWayland, but I don't think
XWayland will ever make me happy.
Do to a bad mixup, the surface listener was never actually fired.
This was accidentally fixed as part of a refactoring in a27fb19,
but the surface listener was broken, and we started crashing. To
fix, just remove the surface listener, as we've mostly been testing
without it.
This time, to make way for MetaSurfaceActorEmpty. This also fixes
destroy effects as a side effect. It still has issues if we try
to re-assign an actor that's already toplevel (e.g. somebody
re-popping up a menu that's already being destroyed), but this
will be fixed soon.
The idea here is that MetaWindowActor will do the unparenting of
the surface actor when it itself is destroyed. To prevent bad issues
with picking, we only make the surface actor reactive when it's
toplevel.
To prevent the MetaSurfaceActor from being destroyed, we normally
unparent it before we unmanage the window. However, this doesn't
work for XWayland windows, which we unmanage when we get UnmapNotify
or DestroyNotify, not when we get the wl_surface_destroy.
To solve this, add an early hook in meta_window_unmanage that
unparents the surface actor if we have one. At the same time, clean
up the destruction code to remove old comments and assumptions about
how wl_shell behaves.
This is considered "undefined" by upstream. Right now GTK+ does this
a lot, so we shouldn't crash. Let's make them crash instead and send
them an error instead.
Implement support for synchronous subsurfaces commits. This means that
the client can, by calling wl_subsurface.set_sync, cause its surface
state to be commited not until its parent commits.
This will mean there will be will potentially be one more surface state
(regions, buffer) at the same time: the active surface state, the mutable
pending surface state, and the immutable surface state that was pending
on last surface commit.

The placement set by either wl_subsurface.place_above or
wl_subsurface.place_below should be applied when the parent surface
invokes wl_surface.commit.

Don't allow a client to stack a subsurface next to a subsurface with
another parent, or to a non-parent non-subsurface surface.

Since subsurfaces won't have toplevel MetaWindowActors, we need to
use MetaSurfaceActor instead. These are embedded in the MetaWindowActor,
just like MetaShapedTexture was (in fact, MetaSurfaceActor now contains
a MetaShapedTexture)
Once the sizing is properly wired up, we need to make sure that
the size at the initial map is correct, and not always 0, 0 because
the buffer is not yet converted into a CoglTexture by MetaShapedTexture,
otherwise we end up sending out configure events at 1 x 1.
To do so, we cache the surface type in the initial state until the
first commit.

To properly resize clients, we need to send them configure events
with the size we computed from the constraint system, and
then check if the new size they ask is compatible with
our expectation.
Note that this does not handle interactive resizing yet, it
merely makes the API calls work for wayland clients.

Add a new interface, gtk_shell, than can be used by gtk to
retrieve a surface extension called gtk_surface, which will be
used to communicate with mutter all the GTK extensions to EWMH
https://bugzilla.gnome.org/show_bug.cgi?id=707128
Add support for GTK application menus
To do so, we need to be able to set surface state before creating
the MetaWindow, so we introduce MetaWaylandSurfaceInitialState as
a staging area.
The gtk-shell-surface implementation would either write to the
initial state, or directly to the window.
At the same, implement set_title and set_class too, because it's
easy enough.
