670f4f22fe clutter/stage: Remove _clutter_stage_get_max_view_scale_factor_for_rect
Since we now have _clutter_stage_get_views_for_rect(), we can easily
replace _clutter_stage_get_max_view_scale_factor_for_rect() with it and
remove that private method.

90c20b185b clutter/actor: Disconnect from "layout-changed" signal on destroy
While the layout manager of a ClutterActor does get properly unset when
destroying an actor, we currently forget to disconnect the
"layout-changed" signal from it.

So do that, and while at it, also switch to using the signal id for
disconnecting from the signal instead of
g_signal_handlers_disconnect_by_func(), which caused problems before
because it might traverse the signal handler list.

4d7c8d68bc clutter/actor: Mark offscreen-redirect property as flag everywhere
We currently are confusing g_param_spec_enum and g_param_spec_flags for
the offscreen-redirect property of ClutterActor. Since it's actually a
flag, make it a flag everywhere.

Fun fact: This was already partly done with
d7814cf63e, but that commit missed the

455de5d6d3 clutter/align-constraint: Listen to queue-relayout signal of source
Just like the ClutterBindConstraint, the ClutterAlignConstraint should
listen to "queue-relayout" of its source actor, not
"notify::allocation". That's because the latter will queue a relayout
during an allocation cycle and might cause relayout loops.

01609de587 clutter/stage: Clear pick stack when hiding
Hiding a compositor stage is not something that's really supported, but
will still be used by tests, to get closer to a "fresh" stage for each
test case, when the tests eventually start using the mutter provided
stage.

It'll use that stage simply because creating standalone stages isn't
supported.

dcb42d3b25 clutter/actor: Sanity check new allocations
Apparently some shell extensions are setting invalid NaN allocations,
leading to weird crashes like
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1849.

Even though an implementation error like this probably deserves a crash,
those can be hard to debug since the crash can happen anywhere the
allocation is being used later. So let Clutter be the good guy and
prevent implementations from setting invalid allocations by
sanity-checking the ClutterActorBoxes using g_return_if_fail.

720360b07a clutter/actor: Don't allocate actors if only the absolute origin changed
For actors which don't have needs_allocation set to TRUE and where the
new allocation wouldn't be different from the old one, the allocate()
vfunc doesn't have to be called. We still did this in case a parent
actor was moved though (so the absolute origin changed), because we
needed to propagate the ABSOLUTE_ORIGIN_CHANGED allocation flag down to
all actors.

Since that flag is now removed and got replaced with a private property,
we can simply notify the children about the absolute allocation change
using the existing infrastructure and safely stop allocating children at
this point.

9b39e37fee clutter/actor: Notify hidden actors about absolute allocation changes
With commit 0eab73dc2e we introduced an optimization of not doing
allocations for actors which are hidden. This broke the propagation of
absolute origin changes to hidden actors, so if an actor is moved while
its child is hidden, the child will not get
priv->needs_compute_resource_scale set to TRUE, which means the resource
scale won't be updated when the child gets mapped and shown again.

Since we now have priv->absolute_origin_changed, we can simply check
whether that is TRUE for our parent before bailing out of
clutter_actor_allocate() and if it is, notify the whole hidden sub-tree
about the absolute origin change.

7abf0f1e2d clutter/stage: Set viewport without getting the last allocation
When getting the last allocation using
clutter_actor_get_allocation_box(), Clutter will do an immediate
relayout of the stage in case an actor has an invalid allocation. Since
the allocation is always invalid when the allocate() vfunc is called,
clutter_stage_allocate() always forces another allocation cycle.

To fix that, stop comparing the old allocation to the new one to find
out whether the viewport changed, but instead use the existing check in
_clutter_stage_set_viewport() and implement the behavior of rounding the
viewport to the nearest int using roundf() (which should behave just as
CLUTTER_NEARBYINT()) since we're passing around floats anyway.

0a37c32a72 clutter/actor: Update absolute_origin_changed inside set_allocation()
When manipulating the allocation of a ClutterActor from an allocate()
vfunc override, clutter_actor_set_allocation() is used to let Clutter
know about the changes.

If the actors allocation or its absolute origin did not change before
that, this can also affect the actors absolute_origin_changed property
used by the children to detect changes to their absolute position.

So fix this bug (which luckily didn't seem to affect us so far) and set
priv->absolute_origin_changed to TRUE in case the origin changes inside
clutter_actor_set_allocation_internal(). Since this function is always
called when our allocation changes, we no longer need to update
absolute_origin_changed in clutter_actor_allocate() now.

Since a change to the absolute origin always affects the resource scale,
too, we also need to move that check from clutter_actor_allocate() here
to make sure we update the resource scale.

9f121a211d clutter/actor: Always reset absolute_origin_changed after relayout
Since the introduction of the shallow relayout functionality it's
possible to start an allocation cycle at any point in the tree, not only
at the stage. Now when starting an allocation at an actor that's not the
stage, we'd still look at the absolute_origin_changed property of this
actors parent, which might still be set to TRUE from the parents last
allocation.

So avoid using the parents absolute_origin_changed property from the
last allocation in case a shallow relayout is being done and always
reset the absolute_origin_changed property to FALSE after the allocation
cycle.

This broke with the removal of the ABSOLUTE_ORIGIN_CHANGED
ClutterAllocationFlag that was done in commit dc8e5c7f.

f8e2234ce5 backends/native: Drop external keyboard detection for ::touch-mode
This cannot be made to work reliably. Some factoids:

- Internal devices may be connected via USB.
- The ACPI spec provides the _PLD (Physical location of device) hook to
  determine how is an USB device connected, with an anecdotal success
  rate. Internal devices may be seen as external and vice-versa, there is
  also an "unknown" value that is widely used.
- There may be non-USB keyboards, the old "AT Translated Set 2 Keyboard"
  interface does not change on hotplugging.
- Libinput has an internal series of quirks to classify keyboards as
  internal of external, also with an "unknown" value.

These heuristics are kinda hopeless to get right by our own hand. Drop
this external keyboard detection in the hope that there will be something
more deterministic to rely on in the future (e.g. the libinput quirks
made available to us directly or indirectly).

0b6a3166ed clutter/text: Also queue relayout if the actor has no valid allocation
In clutter_text_queue_redraw_or_relayout() we check whether the size
of the layout has changed and queue a relayout if it did, otherwise we
only queue a redraw and save some resources.

The current check for this also queues a redraw if the actor has no
valid allocation. That seems right on the first glance since the actor
will be allocated anyway, but we actually want to call
clutter_actor_queue_relayout() again here because that also invalidates
the size cache of the actor which might have been updated and marked
valid in the meantime.

So make sure the size cache is always properly invalidated after the
size of the layout changed and also call clutter_actor_queue_relayout()
in case the actor has no allocation.

This fixes a bug where getting the preferred width of a non-allocated
ClutterText, then changing the string of the ClutterText, and then
getting the preferred width again would return the old cached width (the
width before we changed the string).

The only place where this bug is currently happening is in the overview,
where we call get_preferred_width() on the unallocated ClutterText of
the window clone title: When the window title changes while the
ClutterText is unallocated the size of the title is going to be wrong
and the text might end up ellipsized or too large.

It's effectively used by mutter by abusing a ClutterTimeline to scedule

b8003807b0 clutter/stage: Make clutter_stage_schedule_update() always schedule
We could call clutter_stage_schedule_update() and it wouldn't actually
schedule anything, as the master frame clock only tries to reschedule if
1) there is an active timeline, 2) there are pending relayouts, 3) there
are pending redraws, or 4) there are pending events. Thus, a call to
clutter_stage_schedule_update() didn't have any effect if it was called
at the wrong time.

Fix this by adding a boolean state "needs_update" to the stage, set on
clutter_stage_schedule_update() and cleared on
_clutter_stage_do_update(), that will make the master clock reschedule
an update if it is TRUE.

c2c4f74923 clutter/stage-view: Add tile based shadow damage detection
Compare, tile by tile, whether actual damage actually changed any
pixels. While this requires mmap():ing DMA buffers and comparing their
content, we should only ever use shadow buffers when we're using the
software renderer, meaning mmap() is cheap as it doesn't involve any
downloading.

This works by making the shadow framebuffer double buffered, while
keeping track of damage history. When we're about to swap the onscreen
buffer, we compare what part of the posted damage actually changed,
records that into a damage history, then given the onscreen buffer age,
collect all actual damage for that age. The intersection of these tiles,
and the actual damage, is then used when blitting the shadow buffer to
the onscreen framebuffer.

11f224f4b0 clutter/box-layout: Remove child meta
ClutterBoxLayout's layout policy of using the generic ClutterActor
align/expand properties for children that are expanded and a custom
meta otherwise is confusing, in particular as the x-fill/y-fill
defaults don't match the default CLUTTER_ACTOR_ALIGN_FILL align.

StBoxLayout's own custom child meta (which was deprecated last
cycle) is probably the only consumer. And luckily, the St meta
uses different x-fill/y-fill default that match the ClutterActor
defaults, so removing it will not affect code that doesn't use

dc8e5c7f8b clutter/actor: Replace ABSOLUTE_ORIGIN_CHANGED flag with a property
The ABSOLUTE_ORIGIN_CHANGED allocation flag is only really useful to
propagate the information of the absolute origin of an actor having
changed inside Clutter. It wasn't used anywhere else besides for some
debug messages and it probably shouldn't be used in custom layout
implementations anyway since 1) actors shouldn't have to be aware of
absolute allocation changes and 2) it doesn't factor in changes to the
transformation matrix of a parent.

Also the propagation of absolute origin changes using this flag broke
with commit 0eab73dc2e and now hidden actors are no longer notified
about those changes.

Additionally, this flag gets in the way of a few potential optimizations
since it has to be propagated even if the allocation box of the child
hasn't changed, forcing a reallocation of the child.

affb3de829 clutter/actor: Don't layout children inside set_allocation()
Now that we no longer have the DELEGATE_LAYOUT we expect all actors
overriding the allocate() vfunc to allocate their children themselves.

Since clutter_actor_set_allocation() is only called from custom
vfunc_allocate() implementations, the condition in
clutter_actor_maybe_layout_children() would always fail, which makes
calling the function useless anyway.

24d7a7ad0b clutter: Remove DELEGATE_LAYOUT allocation flag
The CLUTTER_DELEGATE_LAYOUT flag is unintuitive and makes the allocation
process inside Clutter unnecessarily complicated. It's very easy for
actors overriding the allocate() vfunc to layout their children
themselves (in fact most of them do this), and it also never made sense
that clutter_actor_set_allocation() does eventually layout children.

There was no ClutterActor implementation in mutter or gnome-shell which
actually used the DELEGATE_LAYOUT flag, but even without it, it's fairly
easy to archive the same behavior now: In the allocate() override,
adjust the allocation as wanted, then chain up to the parent vfunc
without calling clutter_actor_set_allocation().

So remove the CLUTTER_DELEGATE_LAYOUT flag, which will allow making the
relayout code in Clutter a bit easier to follow.

a7bf6322e3 clutter/actor: Use priv->parent instead of public API sometimes
The public API to get the parent actor, clutter_actor_get_parent() does
a type check whether the actor is actually a ClutterActor. In case of
_clutter_actor_apply_relative_transformation_matrix(), which is called
recursively and very often during the paint process, this type check
shows up with almost twice the amount of hits than the actual matrix
multiplication.

So use the parent pointer directly in some code paths that are executed
very often and avoid the expensive type checking there, we can do that
since both places are not public API.

Since a NULL redraw_clip means that a full view redraw should be done

in clutter_stage_view_add_redraw_clip()), the fb_clip_region should
always be set to a reasonable region that's either the whole view or
individual regions inside the view.

Right now we're checking for the DISABLE_CLIPPED_REDRAWS debug flag
after creating the fb_clip_region and adjusting the redraw_clip. That
means that if may_use_clipped_redraw was TRUE, the redraw_clip will
still be set to the region and thus cause the stage to only be partially
redrawn. Since we don't push a clip to the framebuffer though
(use_clipped_redraw is now FALSE), parts of the view will get corrupted.

To fix that, disable clipped redraws right away if the debug flag is
set. This also allows removing the may_use_clipped_redraw bool and

This also disables a few relatively unrelated interactive tests, as they
rely on ClutterAnimation to implement some animations they use to
illustrate what they actually test.

As interactive tests currently are more or less untestable due to any
interaction with them crashing, as well as they in practice means
rewriting the tests using non-deprecated animation APIs, they are not
ported right now. To actually port the interactive tests, it needs to be

793a9d45e1 clutter/stage-cogl: Fix painting the redraw clip with the damage region
The redraw clip that's painted together with the damage region has to be
copied earlier than we do right now. That's because if
PAINT_DAMAGE_REGION is enabled, buffer age is disabled and thus
use_clipped_redraw is FALSE. That means the redraw_clip is updated and
set to the full view-rect. If we copy the queued_redraw_clip after that,
it's also going to be set to the full view-rect. So copy the redraw clip
a bit earlier to make sure we're actually passing the real redraw clip
to paint_damage_region().

Also keep the queued_redraw_clip around a bit longer so it can actually
be used by paint_damage_region() and isn't freed before that.

While at it, move paint_damage_region() from swap_framebuffer() into
clutter_stage_cogl_redraw_view() so we don't have to pass things to
swap_framebuffer() only for debugging.

e74c2e42cf clutter/stage: Don't assume stage relayouts reallocate everything
With the introduction of "shallow" relayouts, we are now able to enter
allocation cycles not only at the stage but also deeper down the
hierarchy if we know an actors allocation isn't affected by its children
since the NO_LAYOUT flag is set.

Now that means when queuing relayouts it's possible that
`priv->needs_allocation` gets set to TRUE for some actors down the
hierarchy, but not for actors higher up in the hierarchy. An actor tree
where that happens could look like that:

stage -> container -> container2 (NO_LAYOUT) -> textActor

With that tree, if the "textActor" queues a relayout, "container2" will
be added to the relayout hashtable of the stage and the actors "stage"
and "container" will have `priv->needs_allocation` set to FALSE.

Now if another relayout on the stage actor is queued,
`clutter_stage_queue_actor_relayout()` currently removes all the other
hashtable entries in favour of the stage entry, (wrongly) assuming that
will allocate everything. It doesn't allocate everything because in the
example above "container" has `priv->needs_allocation` set to FALSE,
which makes clutter_actor_allocate() return early before allocating its
children, so in the end "container2" will never get a new allocation.

To fix this, stop flushing the relayout hashtable when queuing a
stage-relayout and still add new entries to the hashtable if a stage
relayout is already queued to make sure we still go through all the
previously queued "shallow" relayouts. That shouldn't hurt performance,
too, because as soon as an actor got allocated once, it doesn't need an
allocation anymore and should bail out in clutter_actor_allocate() as
long as it's absolute position didn't change.

Disabling a click action after a button-press but before a

captured-event and never disconnect.

This change fixes it by making sure the captured-event is only

92710d8f89 clutter/stage-cogl: Check for buffer age early
Fix a regression that got introduced with
c483b52d24 where we started passing the
redraw_clip to paint_stage() instead of creating a temporary view_region
for unclipped redraws: In case we detect an invalid buffer age, we fall
back to doing an unclipped redraw after we passed the first check
setting up may_use_clipped_redraw. That means we didn't reset the
redraw_clip to the view_rect, and we're now going to redraw the stage
using the original redraw clip even though we're swapping the full
framebuffer without damage.

To fix that, check for the buffer age before setting up the
fb_clip_region and the redraw_clip and set may_use_clipped_redraw to
FALSE if the buffer age is invalid, too. This ensures the redraw_clip is
always going to be correctly set to the view rect when we want to force
a full redraw.

32c99513c8 clutter/actor: Inherit cloned painting when calculating resource scale
When calculating the resource scale of a clone source, we might end up
in situations where we fail to do so, even though we're in a paint. A
real world example when this may happen if this happens:

 * A client creates a toplevel window
 * A client creates a modal dialog for said toplevel window
 * Said client commits a buffer to the modal before the toplevel

If GNOME Shell is in overview mode, the window group is hidden, and the
toplevel window actor is hidden. When the clone tries to paint, it fails
to calculate the resource scale, as the parent of the parent (window
group) is not currently mapped. It would have succeeded if only the
clone source was unmapped, as it deals with the unmapped actor painting
by setting intermediate state while painting, but this does not work
when the *parent* of the source is unmapped as well.

Fix this by inheriting the unmapped clone paint even when calculating
the resource scale.

This also adds a test case that mimics the sequence of events otherwise
triggered by a client. We can't add a Wayland client to test this, where
we actually crash is in the offscreen redirect effect used by the window
dimming feature in GNOME Shell.

159c83b914 clutter: Move redraw clip management to views
The stage window handled the redraw clip in a global manner; this would
interfere if we want to paint views individually as it'd mean
intersecting views (i.e. mirrored monitors) would loose the redraw clip
once the first view was painted. It also is awkward to have a global
state for something that is built up before redrawing, and only really
valid during paint, due to buffer damage history.

This commits removes all redraw clip management from the stage window,
moving it all into the stage views. When a redraw clip is added to the
stage, every affected view will get the same redraw clip added to it,
and eventually when painted, the stage window (ClutterStageCogl) will
retrieve the redraw clip for each view as it repaints them.

1c98f01a65 renderer-native: Draw stage separately per CRTC
Prior to this commit the stage was drawn separately for each logical
monitor. This allowed to draw different parts of the stage with
different transformations, e.g. with a different viewport to implement
HiDPI support.

Go even further and have one view per CRTC. This causes the stage to
e.g. draw two mirrored monitors twice, instead of using the same
framebuffer on both. This enables us to do two things: one is to support
tiled monitors and monitor mirroring using the EGLStreams backend; the
other is that it'll enable us to tie rendering directly to the CRTC it
will render for. It is also a requirement for rendering being affected
by CRTC state, such as gamma.

It'll be possible to still inhibit re-drawing of the same content
twice, but it should be implemented differently, so that it will still
be possible to implement features requiring the CRTC split.

0c55e87d8f cogl: reduce temporary allocations calculating redraw regions
When calculating regions, a lot of temporary allocations are created. For
the array of rects (which is often a short number of them) we can use
stack allocations up to 1 page (256 cairo_rectangle_int_t). For building
a region of rectangles, cairo and pixman are much faster if you have all
of the rectangles up front or else it mallocs quite a bit of temporary
memory.

If we re-use the cairo_rectangle_int_t array we've already allocated (and
preferably on the stack), we can delay the creation of regions until after
the tight loop.

Additionally, it requires fewer allocations to union two cairo_region_t
than to incrementally union the rectangles into the region.
