We closed all the DMA buffer fds after creating the DMA buffer backed
CoglFramebuffer, which meant that the fds we passed to CoglDmaBufHandle
were already closed. This broke screen casting with DMA buffers.
Fixes: 8509b74532 ("Make DMA buffer allocation format and modifier aware")
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4177>
This makes DMA buffer allocation in all layers take an array of possible
modifiers to allocate using, or zero modifiers if implicit modifiers
should be used.
The format hard coding previously used is moved to the screen cast code,
or in case of the (unused by default) shadow buffer buffers use the same
format as the the CoglOnscreen.
This also means the CoglDmaBufHandle and MetaDrmBuffer got taught how to
distinguish between planes. It's mostly unused in practice, so rather
untested.

Some laptops don't have the integrated GPU come earlier in the PCI topology
which means that when mutter enumerates the GPUs it may select the dGPU
as the primary.
In a laptop context, this is unlikely to work because the eDP panel can
only be actively connected to a single GPU at a time.

And stop passing in the color states from the RendererNative. We also
keep the color states updated by listening for changes in the color
device.
The RendererX11Cm has a single view and no mapping to a specific color
device, so we handle the absense of a color device as well and rely on
ClutterStageView to have the default color states.

This allows us to destroy and create a new offscreen dynamically, when
the rotation or color state changes.
An idle gsource with priority higher than CLUTTER_PRIORITY_REDRAW is
used to ensure the an offscreen exists when required without having to
allocate in the redraw process.

Allow compositing in a linear color space and do so either when forcing
it via the debug controls D-Bus API, or when the experimental HDR mode
is enabled.
This relies on paint nodes etc to actually transform everything into the
linear target color space, which isn't done yet, so enabling it right
now will cause a broken result. Yet, introduce this now, so that
painting can be fixed piece by piece.
Linear blending is automatically enabled on monitors where HDR is
enabled, as this makes it possible to use an linear color space when
blending content from different color spaces with different transfer
functions.
Linear blending requires extra precision, i.e. 16 bit per channel
in the intermediate buffer due how the values are distributed,
so only enable the experimental HDR mode if the Cogl context supports
half float formats.
By default, no intermadiate linear offscreen framebuffer is used.
To test, do e.g.
./tools/debug-control.py --toggle ForceLinearBlending

It's constructed as a native backend headless backend, but uses a custom
monitor manager (based on MetaMonitorManagerNative) that creates a fake
monitor. Rendering is unconditionally done with the surfaceless
renderer.
The test devices used now use virtual devices, meaning some changes to
the tests to e.g. not set names, and not dealing with input devices
directly.

If view initialization fails then don't add the view, rather than
adding a dummy offscreen view. This avoids flooding the log with

In the rare event that hotplugs destroy and then create a new EGLContext

For secondary GPU rendering contexts we currently might choose an EGL
config with a format which is not supported on all primary planes. The
renderer is created when a GPU is detected and lighting up outputs and
thus assigning CRTC and primary planes can happen at any point after
that. This means we have to make sure that all possible plane
assignments will work with the rendering context when we create it.

Fixes: cc7bca073 ("crtc/kms: Dynamically assign primary and cursor planes")
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3512>
When there are a set of primary planes, and a set of CRTCs, where each
plane can be used on multiple CRTCs, we need to make sure that when we
mode set and page flip, each CRTC gets assigned an individual plane that
isn't used with any other CRTC.
Do this during the monitor resource assignments that sets up later to be
applied configurations of the mode setting objects, but with the new
hooks into the backend, so that we don't need to teach the monitor
config manager about planes.

For scanout on a secondary GPU, for the time being try only formats
which are guaranteed to be renderable with GLES3, which notably excludes
10 bpc formats without alpha channel.
v2:
* Use separate format array for 10 bpc formats without alpha.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3139>
If the EGL_KHR_no_config_context extension is supported, use it to
choose a format per onscreen which is compatible with the scanout CRTC
and the GL rendering API used.
Suggested by Jonas Ådahl.
v2:
* Drop code which checked for GLES3 renderability. Makes no sense for
various reasons, in particular that EGLconfigs are about EGLSurfaces,
whereas secondary GPU contexts use an FBO for blitting.
* Use error parameter directly for meta_renderer_native_choose_gbm_format
call (Jonas Ådahl)

- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one
Note we would still want to get rid of the _cogl_texture_init which is something
for the next commit

When running headless, only the invalid modifiers are advertised.
That breaks with the NVIDIA proprietary driver which then rejects the
buffers created with the invalid modifier, and that kills Xwayland,
meaning that running Xwayland on top of a mutter based compositor
headless is not possible.
The reason the modifiers are not sent is because AddFb2 is not supported
when running headless.
Other compositors (weston, wlroots) would still send the modifiers even
without AddFb2, and Xwayland works fine on those compositors when
running headless.
Remove the requirement for AddFb2 to send the modifiers, so that
Xwayland can work fine on top of mutter headless with the NVIDIA
proprietary driver.

If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the
old pending mode sets and start fresh.
We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.

We had a function called "reset_modes()" on MetaRendererNative, but what
it expected to do was to unset all modes on all CRTCs. Despite this, it
had code to unset modes on unconfigured CRTCs, probably because it was
used for multiple things in the past.
Make this a bit easier to follow by renaming the function
"unset_modes()" and fold the function doing the unsetting into the
function itself.
