If the transform matrix is an identity, then positioning wont change and
we can avoid creating the transform node altogether. This is based on
a similar find in GTK today while reducing temporary allocations.
This cuts the number of transforms created in clutter_actor_paint() by
about half under light testing of GNOME Shell from 6.8% to 2.4% of
allocations.
Before:
ALLOCATED TOTAL FUNCTION
[ 20.4 MiB] [ 21.20%] clutter_actor_paint
[ 11.0 MiB] [ 11.45%] clutter_paint_node_paint
[ 6.6 MiB] [ 6.84%] clutter_transform_node_new
[ 2.5 MiB] [ 2.61%] clutter_actor_node_new
After:
ALLOCATED TOTAL FUNCTION
[ 33.4 MiB] [ 24.12%] clutter_actor_paint
[ 26.2 MiB] [ 18.91%] clutter_paint_node_paint
[ 3.4 MiB] [ 2.43%] clutter_actor_node_new
[ 3.3 MiB] [ 2.41%] clutter_transform_node_new
Allocation amounts will have differed due to different amounts of running
time, but the % of allocations has now dropped below
clutter_actor_node_new() which should be expected.

There are two surface roles owning a MetaWindow: MetaWaylandShellSurface
(basis of MetaWaylandXdgToplevel, MetaWaylandXdgPopup,
MetaWaylandWlShellSurface, etc), and MetaXwaylandSurface.
With these two role types, the MetaWindow has two different types of
life times. With MetaWaylandShellSurface, the window is owned and
managed by the role itself, while with MetaXwaylandSurface, the
MetaWindow is tied to the X11 window, while the Wayland surface and its
role plays more the role of the backing rendering surface.
Before, for historical reasons, MetaWindow was part of
MetaWaylandSurface, even though just some roles used it, and before
'wayland: Untie MetaWindowXwayland lifetime from the wl_surface' had
equivalent life times as well. But since that commit, the management
changed. To not have the same fied in MetaWaylandSurface being managed
in such drastically different ways, rearrange it so that the roles that
has a MetaWindow themself manages it in the way it is meant to; meaning
MetaWaylandShellSurface practically owns it, while with Xwayland, the
existance of a MetaWindow is tracked via X11.

The role determines how a relative coordinate is calculated. More
specifically, using clutters API to transform coordinates is only
accurate right after a clutter layout pass but this function is used
e.g. to deliver pointer motion events which can happen at any time. This
isn't a problem for Wayland clients since they don't control their
position, but X clients do and we'd be sending outdated coordinates if a
client is moving a window in response to motion events.
This was already done already, but now move the Xwayland specific logic
to the Xwayland surface role, keeping the generic transformation logic
in the generic actor surface role.

The shell surface role is the one where subsurfaces may exist, and it
has direct relation to the MetaWindowActorWayland which currently has
the subsurface stacking logic.
Instead of directly finding the window actor when dealing with
subsurfaces, notify the parent surface that the subsurface state
changed, so that it can outsource the application of this information to
the role. For subsurface roles, this simply means forward upward to the
parent; for shell surface roles, this means regenerate the surface actor
layering.
This allows us to move away from accessing the window directly from the
surface, which in turn allows us to change the ownership structure of
windows.

If a window already is being pinged, it doesn't make sense to send more
pings to the window, instead we should just wait for that answer or
timeout until we send a new one.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/891
Using a timestamp twice in a row (e.g. when activating two windows in
response to the same event or due to other bugs) will break the window
detection and show a close dialog on the wrong window. This is a grave
error that should never happen, so check every timestamp before sending
the ping for uniqueness and if the timestamp was already used and its
ping is still pending, log a warning message and don't send the ping.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/891
Increase the number of checks whether a window is still responsive and
ping windows on every call to `meta_window_focus()` instead of
`meta_window_activate_full()`. This ensures the window is also pinged in
case normal interaction like clicks on the window happen and a close
dialog will eventually get shown.

Currently when a window is requested to be unredirected, the
corresponding pixmap and texture can get cleared before the window has
been unredirected by the X server. This can result in the windows behind
showing through which causes a short flicker after showing an OSD or
notification when a fullscreen application is running.
Fix this by ensuring the texture is only cleared after the window has
been unredirected by the server.
Similarly when the window is being redirected again, the pixmap of the
window can only be requested after the redirection has been completed by
the server. This currently can happen in a different frame than the next
redraw of the actor resulting in an empty texture until the next redraw.
Fix this by queuing a redraw immediately after redirecting.

By default clutter will show an actor as it is added to a parent. This
means that after we create the window actor, when it's added to the
window group, we implicitly show it. What we really want is to not show
it until the window is supposed to be shown, which happens when
meta_window_actor_show() is called, as showing prior to that, could
cause issues.
Avoid the implicit show by setting the "show-on-set-parent" property on
the window actor to `FALSE` on window actor construction.

We didn't log what we enabled, just g_info():ed what failed to be
enabled. Change this to g_warning() what failed to be enabled, and
g_message() on what was enabled, so that both will be visible in the
logs.

We preserve the core one, which represents the union of all input
devices. It might make sense to make this per-seat in the future,
but certainly the per-device granularity is unused (at last!) and
useless.

XWayland clients get their opaque region set from their window, not the
surface. Doing both resulted in the surface constantly overwriting the
opaque region - effectively disabling culling of XWayland clients.

Devices have capabilities that other parts need to know about. Instead
of having them probe using drmMode* API, outsource this to
MetaKmsDevice. Currently the only capability tracked is HW cursor size.

Turns the cursor setting and movement into cursor plane assignment
primitives. In the current simple implementation, this in turn
translates into legacy drmModeSetCursor() and drmModeMoveCursor() calls.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/930
A cursor plane can now be assigned, and for the simple KMS
implementation, it'll translate into drmModeSetCursor() and
drmModeMoveCursor() calls.
When assignments failed, the cursor planes that failed to be assigned
are communicated via the feedback object.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/930
The current API as all synchronous, so they can be made to return
feedback immediately. This will be needed for the cursor renderer which
needs to know whether it should fall back to OpenGL cursor rendering.

meta_kms_update_process_..() makes it sound like it's a MetaKmsUpdate
function called update_..() but in fact it's a MetaKms function that
calls the corresponding process-update impl function. Clear up this
naming confusion.
