797c349245 clutter/paint-context: Add 'no-cursors' paint flag
Will be used by the stage to not paint the overlays. We skip all
overlays since overlays are only ever used for pointer cursors when the
hardware cursors cannot or should not be used.

c7ad9b33c2 clutter/stage: Add API to paint to a custom target
Either onto a framebuffer, or into a CPU memory buffer. The latter will
use an former API and then copy the result to CPU memory. The former
allocates an offscreen framebuffer, sets up the relevant framebuffer
matrices and paints part of the stage defined by the passed rectangle.

This will be used by a RecordArea screen cast API. The former to paint
directly onto PipeWire handled dma-buf framebuffers, and the latter for
PipeWire handled shared memory buffers.

858c12e73f clutter/paint-context: Add paint flag
A paint flag affects a paint operation in ways defined by the flags.
Currently no flags are defined, so no semantical changes are defined
yet. Eventually a flag aiming to avoid painting of cursors is going to
be added, so that screen cast streams can decide whether to include a
cursor or not.

Changes for gnome-3-36: Removed flag from offscreen context.

b80b465a65 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.

bc47f0a1ac 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.

6f094bd399 clutter/master-clock-default: Sync timelines to hardware vsync
Previously clutter timelines advanced according to `g_source_get_time`.
But that meant the spatial stepping of animations was visibly sensitive to
any irregularities in the main loop. It also represented a time older [1]
than the intended presentation time of each frame.

Now we instead use `master_clock_get_next_presentation_time`. This ensures
we get the smoothness of hardware vsync as well as being closer to the
actual presentation time.

This means, for example, backends like Xorg that move the hardware cursor
independently of repaints will have their animations more closely matching
the hardware cursor position. So the cursor appears to stick more closely
when dragging windows or on the lock screen etc.

[1] "older" = (refresh_interval - sync_delay) = ~14ms for 60Hz

95c1baf3d1 clutter/click-action: Do not process captured event if action is disabled
Disabling a click action after a button-press but before a
button-release is captured makes ClutterClickAction connect to
captured-event and never disconnect.

This change fixes it by making sure the captured-event is only
processed if the action is still enabled, otherwise releasing
the action (reset state) and propagating the event.

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.

86ccc28413 clutter/cogl/stage: Rename have_clip to is_full_redraw
The 'have_clip' variable has repeatedly confused me to meaning that
there is a clip. What it actually means is that the effective clip
covers the whole view; the 'redraw_clip == NULL' meaning full redraw is
an important implementation detail for the context, and makes the
intention of the variable unclear; especially since we will after a
couple of blocks will *always* have a clip, just that it covers the
whole view.

Rename the variable to 'is_full_redraw' and negate the meaning, aiming

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.

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.

dcba7c5044 clutter: Add ClutterSeat::touch-mode boolean property
And the corresponding getter. This property returns FALSE by default
and must be overridden by subclasses. This will allow gnome-shell to
hook up specific behavior that should not happen on mouse+keyboard
setups.

2731be6929 clutter/actor: Use the new shallow relayout API
If an actor sets flag `CLUTTER_ACTOR_NO_LAYOUT` then that means it
is (or should be) unaffected by `queue_relayout` calls in its children.
So we can avoid propagating `queue_relayout` all the way up to the stage
and avoid a full stage relayout each time.

But those children whose parent has `CLUTTER_ACTOR_NO_LAYOUT` still need
to be allocated at some point. So we do it at the same point where it
happened before. Only we now queue a *shallow* relayout so the `allocate`
run on the next frame doesn't need to descend the whole actor tree anymore.
Only a subtree and hopefully very small.

For free-floating and top-level actors this provides a measurable
performance benefit. According to Google Profiler, calls to
`_clutter_stage_maybe_relayout` are now so cheap that they no longer show
up in performance profiles.
