For each libinput scroll event we generate two clutter events
(continuous and discrete), one of them marked as emulated. libei
explicitly specifies that emulation of scrolling must be done in the
client (if desired) so drop the emulated one.

This is used as the minimum refresh rate in the variable refresh rate
range.
This value is expected to be found in the DisplayPort and eDP EDID of
every monitor that supports variable refresh rate.
It is also found in the HDMI EDID of some monitors that support
variable (FreeSync), but most likely not all of them. The rest require
parsing the AMD vendor extension which libdisplay-info doesn't
support.
No fallback is implemented for cases where libdisplay-info support is
disabled.

Frame synchronization is enabled for a view as long as it's
applicable to be enabled. It is considered applicable if it's both
requested for the onscreen and if the onscreen uses a CRTC which is
configured with a variable refresh rate mode.
When frame synchronization is enabled, it enables both the the variable
scheduling mode of ClutterFrameClock and the variable refresh rate
property for the CRTC.
Changes in the frame synchronization mode are applied asynchronously,
before the next frame is drawn.

Add variable refresh rate output modes for connectors that are VRR
capable when VRR is not disabled for the GPU.
Variable refresh rate output modes are sorted before their fixed
refresh rate counterparts. They are also marked as the preferred mode
for the output between the two.

When VRR is not disabled for a GPU, create two variants of every
display mode: one with fixed refresh rate and another with variable
refresh rate.
The variable refresh rate modes are not used yet. They will be used
in a following commit.

This can be used to disable VRR in specific drivers and hardware
combinations where it is found to be problematic.
No default rules are added for now to encourage testing.

Require the "variable-refresh-rate" keyword under the
"experimental-features" gsetting to enable the feature for now.
It would no longer be required once the experience with variable
refresh rate is good enough for general use and handles all common
use cases well.

Use a sufficiently low refresh rate to calculate the CRTC deadline
when variable refresh rate is enabled. This is done to avoid cursor
updates from driving the monitor refresh rate.
It's not great solution and is sometimes not enough, but it avoids
stutter in the main content as a result of cursor movement in most
cases.
The unfortunate downside of this approach is that cursor movement
would usually only update with the main content and would not be
smooth when the main content updates are not frequent enough.
A better solution may use an approach similar to LFC (Low Framerate
Compensation) to insert cursor-only updates between updates of the
main content, but achieving adequate results with an approach of this
nature requires more research and experimentation.

It is not trivial to accurately estimate the expected presentation
time with variable refresh rate, and not doing so only affects debug
prints.
No change in behavior for now because the expected presentation time
is always calculated. A following commit will introduce a case where
it is not.

Add functions to update and monitor the value of the "VRR_ENABLED"
KMS property.
This requires the addition of functions to process CRTC property
updates in both the atomic and the simple KMS backends. The
implementation is similar to the implemention of processing
connector updates.

Commit d48129f5ee broke the displaying of our own drag cursor during window
drags, as now the window cursor is always used, even during stage grabs
(window grabs are just a kind of stage grab).
To fix it, while not regressing on the intention of the other commit, unset
the MetaWaylandPointer surface in case a window drag is active (instead of
all kinds of grabs) by checking via meta_display_is_grab().

QueryDeviceString can successfully return NULL. The convention however
is that when NULL is returned, the error will be set.
This commit makes the returned string an output parameter which allows
us to return the success status and have the error set accordingly.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3614>
The convention is that when a function returns FALSE or NULL, the error
will be set. In this file we call set_egl_error but it might not set an
error. Code of the form
if (egl_do_thing (..., &error))
use_error (error);
will crash in those cases.
This commit makes sure we always set the error even if EGL doesn't give
us an error.

This also removes some g_return_if_fail's because the test suite expects
to be able to create arbitrary KmsUpdates even if they don't make sense
for the real state. We just get lucky that the test suite isn't
constructing updates with color space and hdr changes, yet.

Currently querying support for some output features is done partially
through the OutputInfo and partially via KMS CRTC and Connector objects.
Let's be consistent and use OutputInfo always which works with all
backends and backend types.

The kernel doesn't let us set gamma to passthrough with the legacy API
so we have to trick a bit and create an identity LUT, and also when we
read the KMS state, detect when an identity LUT is active.

Do not include it at header side as it is not part of the installed headers.
Only keep it in cogl-gl-headers.h as it is a private header.
Add it to all the source files that depend on it.

This change adds modifier-aware screencasting support to Mutter.
Implicit modifier support is kept for backward compatibility and the
code fallbacks to implicit modifiers in case any new functionality added
for explicit modifier support fails.
The advertised modifiers are retrieved by a call to
eglQueryDmaBufModifiersEXT() function. The "external only" modifiers are
excluded as Mutter uses the buffers created with the explicit modifiers
as renderbuffers. Support for implicit modifiers is checked with a test
allocation since there are drivers that do not support them.
This change also removes various implicit modifier support checks that
disable DMA-BUF screen casting support globally as they are no longer
needed. DMA-BUF support for screencasting is determined by the available
formats and modifiers case-by-case now.
It also effectively enables DMA-BUF screencasting on NVIDIA hardware as
well since GBM buffer objects with linear modifiers are no longer used
by default to create a renderbuffer object for screencasting.

meta_render_device_gbm_allocate_dma_buf() function is updated to take a
list of modifiers. If no modifiers are specified, the modifier is
selected by the allocator, and implicit modifiers are used to import the
created DMA-BUF.

They are float in libdisplay-info and our own EDID parsing also returns
a float but when then converted both to an integer. Especially the min
luminance can be <1.
We also don't need a variable for indicating presence of a CTA Static
Metadata block. The values are all zero if it is absent.
