like:
clutter/clutter/meson.build:628: DEPRECATION: Library mutter-clutter-4
was passed to the "libraries" keyword argument of a previous call to
generate() method instead of first positional argument. Adding
mutter-clutter-4 to "Requires" field, but this is a deprecated behaviour
that will change in a future version of Meson. Please report the issue
if this warning cannot be avoided in your case.
This makes the build less verbose, as all .gir generation except for
clutters didn't pass --quiet to g-ir-scanner, making it output long
linking commands. Do this by adding a common introspection_args
variable.
While at it, put -U_GNU_SOURCE in there too, as it was always passed
everywhere as without it the scanner would log warnings.
The actor-shader-effect test actors are 50px wide, but we check the 51st
pixel. This went along undetected until "clutter: Avoid rounding
compensation when invalidating 2D actors" because the paint volumes were
made slightly bigger and the shaders paint all over them (I guess nobody
noticed those actors being actually ~52px wide).
Update the test to check the middle of the opposite edge, so we keep neatly
rounded numbers.
The test does a clutter_actor_set_scale_full() call that only updates
the scale center (i.e. no changes to scale-x/y), but expects to receive
notifications of actor scale changes.
Since "Revert "Revert "ClutterActor: Optimize away idempotent
scale/position updates"" these are optimized away, so just drop the
assumption.
This allows the redraw clip to be more constrained, so MetaCullable doesn't
end up rendering portions of window shadows, frame and background when a
window invalidates (part of) its contents.

Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.
In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.
Removing it means less code, less branches when running,
and one less config option to deal with.
This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

Externally setting the sync-to-vblank setting was a feature
added as a workaround to old Intel and ATI graphic cards, and
is not needed anymore. Furthermore, it doesn't make sense to
change it on a compositor whatsoever.
This commit removes all the ways to externally change this
setting, as well as the now unused API.

The xf86-input-wacom driver exports a property with the tool type as known by
the driver. This is a more reliable choice than guessing based on the device
name.
In the touchscreen case, we simply use is_touch_device() to guess which one of
the two options it is. Note that this code should never be hit anyway as we
would've succeeded earlier with a previous is_touch_device() call.
If we are lucky enough and the parent actor has the CLUTTER_ACTOR_NO_LAYOUT
flag, we would skip the relayout, but still redraw the parent actor in its
entirety.
In these cases, we can at least just redraw the area affected by the actor
being shown/hidden.
These calls don't actually affect the layout, but the paint order.
It seems safe to skip the full relayout/repaint of the parent actor,
and redraw only the area occupied by the affected child.
cogl_(fromebuffer)_set_viewport will implicitly cast away the fraction
of a floating point number, meaning if a coordinate calculation
resulted in just below the integer (which for example ~1.75 scaling on
a 1920x1080 did), we'd set a one pixel too narrow viewport. Fix this by
always rounding the floating point to the closest int before passing,
avoiding the precision loss.

This is to ensure we're rendering a red damage area that actually
represents what is being damaged.
Fixes an always-fullscreen red damage on bare metal Wayland and
GNOME Shell.
This is useful to visualize which parts of the screen are being
damaged.
Add a new 'damage-region' value for CLUTTER_PAINT and paint the
damaged regions accordingly.
This commit includes following fixes for a few shell scripts:
1. Follow the best practice of quoting variables everywhere unless they
are used in places where word-splitting and globbing can never happen.
2. Replace `command` with $(command) because the latter is easier to use
and read.
3. Don't use "$@" in places expecting a string because it is an array
of strings instead of a single string.
Bash is not always installed in /bin and we should not hardcode the path
of it in source code which is expected to be built on many operating
systems and distributions.
Since most scripts using #!/bin/bash here doesn't have any bashism,
they can be converted to #!/bin/sh instead of using /usr/bin/env trick.
If a device (virtual or real) is removed while there are remaining
events queued for that device, the event loop may try to access the
event freed memory.
To avoid the issue, add a reference to the device when the event is
created or copied, and remove the reference once the device is freed.

Mostly as expected, this port is also trivial. A small cleanup
accompanies this patch, making gen_texcoords_and_draw_cogl_rectangle()
receive the framebuffer that it should draw into.
Because ClutterText has a somewhat convoluted drawing routine,
replacing cogl_rectangle() here isn't as straightfoward as the
effects were.
A new CoglPipeline is now part of the ClutterText struct, and
is used to set the color of the background or the selection.
Another change is paint_selection() now receives a framebuffer
to draw into. The check for NULL framebuffer does not make
sense here, since there is always a draw framebuffer set
when in the drawing function. Because of that, the check is
now gone.
All those effects have the same basic pattern of setting a
color of a pipeline, then drawing a rect with cogl_rectangle().
Thus, replacing those was as easy as retrieving the draw
framebuffer and calling cogl_framebuffer_draw_rectangle() on it.
The default implementation of ClutterActor.pick() uses
cogl_rectangle() to draw the rectangle with the color
for picking.
Replace that by cogl_framebuffer_draw_rectangle(). A
static color pipeline had to be created in order to
hold the pick color.
Instead of using cogl_read_pixels(), which is deprecated and
uses the implicit framebuffer, pass the current CoglFramebuffer
and use cogl_framebuffer_read_pixels().
Another case of a simple and direct API translation. Instead of
using the deprecated cogl_clear() function, replace it by the
non-deprecated cogl_framebuffer_clear().
The events-touch test tested that clutter could properly process evdev
touch events. It used uinput to post evdev touch events, thus only ran
when runnig the test as root. Running as non-root it'd just silently
pass. As Clutter doesn't process evdev touch events anymore,
libinput does, so the test is fairly pointless, so remove it.
Pausing the master clock didn't actually pause it if there was already a
scheduled frame in progress. This is problematic if one actually expects
to see no new frame scheduling to happen after pausing, for example it
caused actor 'pre-paint' to be signalled on actors, but nothing was ever
painted.
Avoid this by destroying the master clock source when pausing, and then
recreating it when resuming.

When profiling gnome-shell it was found that one of the main triggers
of `clutter_actor_queue_relayout` during animations was
`clutter_actor_set_margin_internal` continuously setting the same
zero margins. That's obviously pointless but also expensive since it
incurs full stage relayouts and reallocation. So just avoid redundant
margin changes.
Helps to further improve:

Almost a decade old, lets just assume it's there. This makes the button
on cally-atktext-example work again when building with meson, and
probably other things too.
If texture allocation fails (e.g. on an old GPU with size limit 2048)
then `update_fbo` would return `FALSE` but leaves `priv->offscreen`
as non-NULL. So the next paint will try to use the offscreen with a
`NULL` texture and crashes. The solution is simply to ensure that
`priv->offscreen` is NULL if there is no `priv->texture`, so the default
(non-offscreen) paint path gets used instead.
