It is generally assumed here and there that the pointer at all point in
time is within some logical monitor, if there is any logical monitor to
be within.
With the input thread, this was for a short amount of time not reliable,
resulting in crashes in combination with hotplugging or suspend/resume,
where monitors come and go quickly.
What happens is that the pointer at first is within a logical monitor,
but when that logical monitor is removed, while the new monitor
viewports are handed to the input thread, the constraining happens
asynchronously, meaning there is a time between between the new
viewports are sent, and before clutter_seat_query_state() starts
reporting the constrained position.
If a new client mapped a maximized window during this short time frame,
we'd crash with
#0 meta_window_place at ../src/core/place.c:883
#1 place_window_if_needed at ../src/core/constraints.c:562
#2 meta_window_constrain at ../src/core/constraints.c:310

#8 wl_closure_invoke at ../src/connection.c:1025
#9 wl_client_connection_data at ../src/wayland-server.c:437
The fix for this is to make sure that the viewports are updated and
pointers constrained synchronously, i.e. the main thread will wait until
after the input thread is done constraining before continuing.

The CRTC cursor sprite scale was incorrectly assumed to be always 1.0
when using the default not-scale-monitor-framebuffer mode. This is
harmless in most cases, as most clients provide HiDPI capable cursors,
but for the ones that didn't, we'd end up drawing their cursors
unscaled, when using the cursor planes.
Fix this by using the "texture scale" which is what is intended for
this.

Cursor planes tend to be ARGB8888 and support no other format (ideally
we should not hard code this, but un-hard-coding that is for another
day), and if we put e.g. a XRGB8888 buffer in there, it'll either result
in the gbm_bo allocation failing (it doesn't allow USE_CURSOR with any
other format) or mode setting failing if using dumb buffers directly.
In the former case, we'll fall back to OpenGL indefinitely, and in the
latter, we'll have failed mode sets as long as we try to set the invalid
cursor buffer as the cursor plane.
Change things to process all buffers that are not ARGB8888 using the
scale/rotate machinery we already have, turning XRGB8888 into ARGB8888.

Some mice send a value slightly lower than 120 for some detents. The
current approach waits until a value of 120 is reached before sending a
low-resolution scroll event.
For example, the MX Master 3 sends a value of 112 in some detents:
detent detent
| | |
^ ^ ^
112 REL_WHEEL 224
As illustrated, only one event was sent but two were expected. However,
sending the low-resolution scroll event in the middle plus the existing
heuristics to reset the accumulator solve this issue:
detent detent
| | |
^ ^ ^ ^
REL_WHEEL 112 REL_WHEEL 224
Send low-resolution scroll events in the middle of the detent to solve
this problem.

Previously, when scroll was received in a remote session, it was handled
as continuous scroll.
This generated issues with clients without high-resolution scroll
support as the code path in charge of accumulating scroll until 120 is
reached was not used and therefore discrete scroll events were not being
generated.
Handle scroll generated in a remote session as discrete scroll when the
source is CLUTTER_SCROLL_SOURCE_WHEEL to fix this issue.

This is an old relic from when ClutterStageView was being added, and
tests were somewhat prepared to be able to test the "X11 style" of
things, with the nested backend some how managing to emulate that.
Lets drop that stuff, it isn't used by the test suite, and isn't useful
anyway; if we want to test X11 configurations, we should use the actual
X11 backend, which didn't make use of this anyway.

This adds a copy of the calibration test profile and sets up a test to

We might fail with some part of the color profile construction and
initialization. For example there might be a system wide profile with
the same ID as one we attempt to add from a local ICC directory. When
this happens, we should drop these profiles, and use the ones from the
system instead.
Profiles may fail to initialize for other reasons too, e.g.
unpredictable colord errors, or other I/O issues.

If our profile wasn't fully initialized, we'd try to clean it up, in an
attempt to handle race conditions by finding synchronously then cleaning
it up, but don't attempt this if the profile is ready, as that means we
didn't create one in the first place.

This is instead of getting anything from the CdDevice. This avoids a
crash when CdDevice isn't successfully setup but something still tries
to look up the filename of the ICC profile.
This isn't a real bug fix for anything, but there is no reason having to
rely on CdDevice for this anyway, and as we don't really have control of
it, it's less reliable of containing something valid.

When creating a render device, we create a temporary EGLContext where we
then query the `GL_RENDERER` string to check whether the renderer is any
of the known software renderers. After we're done, we destroy the
context and move on.
This should be fine as according to specification eglDestroyContext(),
with the context being actually destroyed a bit later when it's no
longer current, but mesa, when running RK3399 (Pinebook Pro), this
results in a crash in a future eglMakeCurrent():
#0 in dri_unbind_context () at ../src/gallium/frontends/dri/dri_context.c:266
#1 in driUnbindContext () at ../src/gallium/frontends/dri/dri_util.c:763
#2 in dri2_make_current () at ../src/egl/drivers/dri2/egl_dri2.c:1814
#3 in eglMakeCurrent () at ../src/egl/main/eglapi.c:907
...
We can avoid this, however, by calling eglMakeCurrent() with
EGL_NO_CONTEXT on the EGLDisplay, prior to destroying, effectively
avoiding the crash, so lets do that.

EGLStream is incompatible with atomic mode setting, but nvidia-drm when
using libgbm is not, so lets only deny using atomic mode setting when
the render device is an EGLStream based one.

The type of render device used for a specific GPU affects the mode
setting backend that can be used, more specifically, when the render
device is an EGLStream based one, atomic mode setting isn't possible, as
page flipping is done via EGL, not via atomic mode setting commits.
Preparing the render devices before KMS devices means can make a more
informed decision whether to deny-list atomic mode setting for when
a certain GPU uses a EGLStream based render device instance.
This also means we need to translate mode setting devices to render node
devices when creating the render device itself, as doing it later when
creating the mode setting device is already too late.

Currently, the peripheral "output" setting will be unset if Mutter is
deciding automatically the mapped output of a tablet device. In that
case, gnome-control-center will have a hard time figuring out itself
the better output to show the tablet calibration UI, unless it's hand
held by Mutter.
Add this private D-Bus interface so that gnome-control-center can look
up the output as determined by Mutter to bring the missing harmony
between both. This interface consists of a simple method to get the
mapped output for a input device node.

Following the EGL_KHR_swap_buffers_with_damage specification, the
surface damage used by eglSwapBuffersWithDamage does not need to
contain the damage history.
Rework that to initialize swap_region earlier, before appending the
damage history.
This may help optimizing the composition process in some cases (at least
on X11 when EGL_KHR_swap_buffers_with_damage is available) by not
accumulating additional regions as damaged unnecessarily.
