While we shouldn't normally receive crossing events for any windows
except the stage when running nested, we do in case we hold a pointer
grab - just ignore those events instead of taking down the user's
session.
The spec says:
"A server should avoid signalling the frame callbacks if the surface is not
visible in any way, e.g. the surface is off-screen, or completely obscured
by other opaque surfaces."
We actually do have the information to do that but we are always calling
the frame callbacks in after_stage_paint. So fix that to only call when
when the surface gets drawn on screen.

The compositor maintains a ring of shared fences with the X server in order to
properly synchronize rendering between the X server and the compositor's GPU
channel. When all of the fences have been used, the compositor needs to reset
one so that it can be reused. It does this by first waiting on the CPU for the
fence to become triggered, and then sending a request to the X server to reset
the fence.
If the compositor's GPU channel is busy processing other work (e.g. the desktop
switcher animation), then the X server may process the reset request before the
GPU has consumed the fence. This causes the GPU channel to hang.
Fix the problem by having the compositor's GPU channel trigger its own fence
after waiting for the X server's fence. Wait for that fence on the CPU before
sending the reset request to the X server. This ensures that the GPU has
consumed the X11 fence before the server resets it.

If GL advertises this extension we'll use it to synchronize X with GL
rendering instead of relying on the XSync() behavior with open source
drivers.
Some driver bugs were uncovered while working on this so if we have
had to reboot the ring a few times, something is probably wrong and
we're likely to just make things worse by continuing to try. Let's
err on the side of caution, disable ourselves and fallback to the
XSync() path in the compositor.

If we can't put up a popup because grabbing the pointer fails we
immediately dismiss the popup but the client might have made requests
already, in particular it might have commited the surface and in that
case we should ignore it.
https://bugzilla.gnome.org/show_bug.cgi?id=753237
When a client sets an input region or a opaque region to NULL, it
should still be considered a change to the corresponding region on the
actor. This patch makes sure this state is properly forwarded.

This was introduced in commit c6793d477a
to prevent window self-maximisation. It turns out that that bug seems
to have been fixed meanwhile in a different way since the reproducer
in https://bugzilla.gnome.org/show_bug.cgi?id=461927#c37 now works
fine with this special handling removed.
In fact, failing to set window->fullscreen immediately when loading
the initial set of X properties causes us to create a UI frame for a
window that sets _NET_WM_STATE_FULLSCREEN.
This, in turn, might cause the fullscreen constrain code to fail if
the window also sets min_width/min_height size hints to be the monitor
size since the UI frame size added to those makes the rectangle too
big to fit the monitor. If the window doesn't set these hints, we
fullscreen it but the window will get sized such that the UI frame is
taken into account while it really shouldn't (see the reproducer
above).

Since commit 14b0a83f64 we store the
main window monitor instead of computing it every time. This means
that we must now ensure that it's updated before trying to use it
which we do from meta_screen_resize_func() or else we'll crash on an
assertion later on when removing a monitor:
assertion failed: (which_monitor < workspace->screen->n_monitor_infos)
https://bugzilla.gnome.org/show_bug.cgi?id=752674
Some monitors return a bunch of bytes on their display descriptor
which aren't valid utf8 and thus we fail to serialize them later on
for the DisplayConfig DBus API.
Let's fall back to the stringified product code and serial number in
that case.

There's a chance the icon will be animated, so store the XcursorImages
instead of the individual XcursorImage, and handle that as a nimages=1
special case.
API to "tick" a cursor animation, and retrieve current frame timing
information has been added.

They otherwise fall through paths that enable bypass_clutter, this
is necessary so they can be picked by captured-event handlers
along the actor hierarchy.

When placing a popup and the legacy transient wl_shell_surface surfaces,
take the current scale of the window into account. This commit doesn't
fix relative positioning in case a window scale would change, but since
the use case for relative positioning is mostly popups, which would be
dismissed before the parent window would be moved, it should not be that
much of a problem.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Make meta_wayland_surface_get_toplevel_window return the top most window
in case its a chain of popups. This is to make all popups in a chain
including the top most surface have the same scale.
The reason for this is that popups are mostly integrated part of the
user interface of its parent (such as menus). Having them in a different
scale would look awkward.
Note that this doesn't affect non-popup windows with parent-child
relationship, because such windows are typically not an integral part of
the user interface (settings window, dialogs, ..) and can typically be
moved independently. It would probably make sense to make attached modal
dialogs have the same scale as their parent windows, but modal dialogs
are currently not supported for Wayland clients.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Since we scale surface actors given what main output their toplevel
window is on, also scale the window geometry coordinates and sizes
(window->rect size and window->custom_frame_extents.top/left) in order
to make the window geometry represent what is being rendered on the
stage.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
The main monitor of a window is maintained as 'window->monitor' and is
updated when the window is resized or moved. Lets avoid calculating it
every time it`s needed.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Tracking back from the monitor to the output every time we need to
figure out the scale of a window on a monitor is inconvenient, so
propagate the scale from the output to the monitor it is associated
with.

A MetaWaylandSurface was casted into a ClutterActor, but it should have
been the MetaSurfaceActor.
Move out parent_actor and surface_actor out of the loop while at it
since they won't change when iterating.
https://bugzilla.gnome.org/show_bug.cgi?id=745655
Keep the active position state in its original coordinate space, and
synchronize the surface actor with it when it changes and when
synchronizing the rest of the surface state, in case the surface scale
had changed.

We can get this operation in some cases, for example when
we're trying to resize window that cannot be resized.
This can occur with maximized windows that have a border
(without border we couldn't resize them by mouse in maximized state).
In this case we reached abort() beacuse we did not handle this op.

Previously a MetaWaylandOutput could be removed from the current outputs
table (by being unplugged for example). This would result in the global
object being removed and the MetaWaylandOutput instance freed, but the
wl_resource destructor would still try to remove itself from the list of
resources. Trying to do this, it'd try to access its user data pointer
which would point to the freed MetaWaylandOutput instance, and as a
result crash when trying to manipulate the freed data.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
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.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
We may access it during painting even if it has been freed. For now,
manually unset it during the MetaWaylandSurface cleanup; in the future
make MetaWaylandSurface a GObject and make the surface pointer a weak
reference.

Lets use the role when doing role specific commit actions. The
conditions effectively do that anyway, and this way we will get a
compiler warning here whenever we add a new role, as well as we avoid
having different variants of role-determination checks in different
places.

Enable a user to test and debug multi output configurations on Wayland
without having the available hardware by enabling some basic
configuration of the dummy monitor manager.
Currently available configuration options are:
MUTTER_DEBUG_NUM_DUMMY_MONITORS - to set the number of monitors
MUTTER_DEBUG_DUMMY_MONITOR_SCALES - to configure the monitor scales
See src/backends/meta-monitor-manager-dummy.c for detailed description
of the available configuration parameters.
