This is a bit scattered around, with the setter/getter in Clutter, and
it only being only directly honored in Wayland (it goes straight through
device properties in X11).

It's not worth letting these devices have an "unlimited" range of touch

The semantics for libinput events are not as expected here. Besides
it's pointless, as those should arrive per-slot in a burst, and we
cancel on the first event.
We can simply use the Clutter event for this.

As it does seem from a read to libinput code, TOUCH_CANCEL events
actually do contain slot information, and are emitted per-slot.
This means we can avoid iterating over the slots ourselves, they
are still expected to be sent altogether.

We want to coalesce multiple touch events into the same wl_touch.frame
event. Instead of poking internals to peek the touch events (and their
slots) coming at us before we handle them, simplify things by queueing
the event at a slightly lower priority than events, so we are ensured
to handle all pending input events before sending the event.
If there's no pending events, we can just send the frame event. As it
doesn't make sense to hold any longer.

A previously stored width and height of 0 signifies that no previous window
size has been stored. This might be the case if an application starts in
maximized or fullscreen mode. If no previous window size has been stored,
the client needs to determine its own size.

Since commit eb9cd3857d we initialize the allocation of ClutterActors to
an UNINITIALIZED ClutterActorBox. We do that to ensure the actor even
emits notify::allocation in case it got a new valid allocation of
0,0,0,0.
Now there's still the case where an actor gets removed from the
scenegraph and added again to a different parent, in this case we still
don't emit notify::allocation right now in case the new allocation
equals the old one. There's two good reasons to do so though:
1) To Clutter, there's no difference between a newly created actor and
an actor which got removed from the scenegraph, it's not consistent to
always notify the allocation property in the former situation, but not
always notify it in the latter situation.
2) When an allocation changes, Clutter notifies the subtree of that
actor about an absolute geometry change (see the call to
transform_changed() in clutter_actor_set_allocation_internal()). Now
when an actor gets reparented, obviously the absolute geometry might
change, so to make sure transform_changed() is always called in that
case we need to make sure an allocation change happens.
So simply reset the allocation property of the actor to an UNINITIALIZED
ClutterActorBox as soon as it gets unrealized.

We introduced the absolute_origin_changed flag when preparing for the
removal of ClutterAllocationFlags in commit dc8e5c7f8b. Turns out in the
mean-time commit df4eeff6f2 happened, which renders the whole
absolute_origin_changed flag moot.
That's because we now notify the whole subtree about the absolute origin
change by calling transform_changed() when the allocation of an actor
changes. transform_changed() traverses the subtree and calls
absolute_geometry_changed() on every actor immediately, which renders
the whole propagation of the absolute_origin_changed flag obsolete.

Since we now moved the queuing of relayouts into the mapping and
unmapping functions, we no longer need to do it when adding or removing
a child, that's because removing a child always unmaps the child, and
adding it to a stage (if it's visible) will map it.
So remove those calls to queue_relayout() since they're no longer
needed.
With the above we no longer queue a relayout in
clutter_actor_add_child_internal(), that means there's one place where
we need to explicitely queue relayouts now: That's when using the
set_child_at_index/above/below() APIs, those are special because they
avoid unmapping and mapping of actors and would now no longer get a
relayout.

In theory there's no big difference between only handling mapped actors
vs only handling visible actors in clutter_actor_allocate(): The
function is called recursively starting with an actor that is attached
to a stage, so it should only be called on mapped actors anyway.
The behavior of skipping hidden actors was introduced as an optimization
with commit 0eab73dc. Since the last commit, we handle
enable_paint_unmapped a bit better and don't do unnecessary work when
mapping or unmapping, so we can now be a bit stricter enforcing our
invariants and only allow mapped actors in clutter_actor_allocate().
We need to exclude toplevel actors from this check since the stage has a
very different mapped state than normal actors, depending on the
mappedness of the x11 window. Also we need to make an exception for
clones (of course...): Those need their source actor to have an
allocation, which means they might try to force-allocate it, and in that
case we shouldn't bail out of clutter_actor_allocate().
Also moving the clutter_actor_queue_relayout() call from
clutter_actor_real_show() to clutter_actor_real_map() seems to fix a bug
where we don't queue redraws/relayouts on children when a parent gets
shown.

We currently support only one case where an actor can get mapped or
unmapped during painting, that is using
_clutter_actor_enable_paint_unmapped() (although we could arguably do a
better job explicitely forbidding it in other cases). This function is
called when painting ClutterClone or MetaWindowActors during
screensharing. It temporarily (fake) realizes and maps the actor and all
its children so it can get painted.
Now a problem will appear when we'll start coupling layout and the
mapped state of actors more closely with the next commit: Since
enable_paint_unmapped() is meant to be enabled and disabled during every
clone paint, we also notify the "mapped" property twice on every clone
paint. That means with the next commit we would queue a relayout for the
source actor on every clone paint.
To avoid this unnecessary work, check whether we're being painted while
unmapped using the new unmapped_paint_branch_counter. Then avoid queuing
relayouts or invalidating paint volumes in that case.

We're going to enforce some invariants a bit stricter and will only
allow allocating if an actor is mapped, not only visible.
Since actors are only mapped if their parent is mapped and stages are
hidden by default, we need to show the stage to ensure the actors are
mapped before we allocate them. So do that and call clutter_actor_show()
on the stage before fake-allocating the test actors.

Add new private API to ClutterActor, returning TRUE in case the actor is
being painted while unmapped. This is useful for implementations of the
paint() vfunc or for signal handlers of the "notify::mapped" signal.
Use this API in CallyActor to properly detect "notify::mapped" emissions
while painting unmapped, this fixes detecting the case where
painting-unmapped is used for screencasting.

Just like the existing in_cloned_branch counter, add a property which
tracks whether the actor is part of a subtree that's being painted while
unmapped. This is going to be useful for a few things, for example
changing the clutter_actor_is_in_clone_paint() API to use
enable_paint_unmapped instead of in_clone_paint.

clutter_actor_queue_relayout() detects whether a parent has the
NO_LAYOUT flag set by itself and then queues a shallow relayout for us.
There's no need to duplicate that logic when showing actors, so simply
call clutter_actor_queue_relayout() and let that handle it.

Apparently clutter_paint_volume_union() has problems building the union
of two paint volumes in eye coordinates, that's probably because of the
negative coordinates that come into play there.
Circumvent that by making even more use of Graphene and letting it take
care of computing the union. We do that by creating two graphene_box_t's
from the axis-aligned paint volumes and intersecting those boxes, then
setting our vertices to the new min and max points of the resulting box.

Bug 448183 fixed an issue with _NET_WM_MOVERESIZE_WINDOW not moving a
window by basing the resize on the current (new) rectangle instead of
the original rectangle.
While this fixes the issue with _NET_WM_MOVERESIZE_WINDOW, this also
causes windows with a size increment to move when the resize also
implies a move, such windows might drift while resizing.
Make sure to use the current rectangle for non-interactive resizes only.

The XSizeHints set by X11 clients give a hint to the window manager
about size increment, aspect ratio, base, minimum and maximum size, etc.
When an X11 client changes those values, there is a good chance that it
will affect the actual window size in some way, and mutter rightfully
queue a window resize in that case.
However, mutter does not check if any of the hints have actually changed
and unconditionally queue a window resize whenever a client changes its
WM_NORMAL_HINTS property.
That can be a problem when a zealous client such as xterm decides to
update its WM_NORMAL_HINTS property on resize, because in return mutter
will queue a non-user driven resize in the middle of user-driven events,
hence defeating the purpose of the META_MOVE_RESIZE_USER_ACTION flag.
To avoid that issue, make mutter a bit smarter and avoid queuing a
window resize if the XSizeHints haven't actually changed.

On interactive resize, mutter calculates the difference in size based on
the pointer location and relies on window constraints to ensure the
minimum size is honored.
Wayland however does asynchronous window configuration, meaning that not
checking for size hints early enough may lead to the window moving as
the locations was initially computed on a size which will be invalidate
by the client eventually.
Make sure to respect the client size hint on update_resize() so that we
don't end up with a window moving unexpectedly when the client
eventually acked the configuration.

portrait mode panels
Many tablets have a native portrait mode panel, yet come with a keyboard dock,
where the device gets docked in landscape mode. To avoid the display being
on its side when mutter starts while the tablet is docked, we need to take
the accelerometer reported orientation into account even if there is a
tablet-mode-switch which indicates that the device is NOT in tablet-mode
(because it is docked).
Add special handling for the first time the "orientation-changed"
signal gets signalled by the orientation-manager, which happens after it
has successfully claimed the accelerometer with iio-sensor-proxy.
The added special handling of the initial "orientation-changed" signal
does a number of checks:
1. panel_orientation_managed is false because of the tablet-mode-switch and not
because of other reasons.
2. The device has a native portrait mode panel (and thus likely needs rotation
to display the image the right way up when docked).
If all these checks succeed then it continues with creating a new
monitors-config based on the orientation ignoring the panel_orientation_managed
value (for the initial/first "orientation-changed" signal only).

panel_orientation_managed changes
The orientation reported by the orientation_manager may have changed while
panel_orientation_managed was false. So when panel_orientation_managed
changes to true we should re-check the orientation.
This fixes the orientation not being correct when e.g. taking a 360 degree
hinges 2-in-1 in clamshell mode (so landscape orientation) and then folding
it into tablet mode while holding it in portrait orientation.
