A Vulkan renderer for weston, based on the GL renderer.
The goal is to impose the least requirements as possible on Vulkan
implementations, as to allow even Vulkan 1.0 (or early development)
drivers to run a Wayland compositor. Any additional features or
extensions are made optional if possible.
Currently supports drm, wayland, x11 and headless backends.
As of this implementation, this is still considered an experimental
renderer.

Add API to create color profiles from parameters. It is a public API
that should be used by the frontend and also by the color management
protocol implementation.
Currently our protocol implementation does not support clients that want
to create color profiles from parameters, and this is a step towards
supporting that.
As warned in "color: add get_color_profile_from_params() to color

parameters. This just creates a boilerplate color profile that we're

helper lib' and 6293ab1f90, 'libweston, shared: Move out
weston_shell_get_binding_modifier' moved things out of libweston, and
libweston implicitly depends on xkbcommon.
Rather than just depending on dep_xkbcommon use the deps_for_libweston_users

of libweston/meson.build and include it in the main meson.build as
libweston/meson.build would have a circular dependency on

Add a separate PipeWire backend based on the PipeWire plugin. The backend
requires PipeWire 0.3.x.
The PipeWire backend can be used as a standalone-backend backend for streaming
and composing Wayland clients to PipeWire.
The backend supports the on-demand creation of heads via the
weston_pipewire_output_api_v1. It also supports per-output pixel format
configuration via a gbm-format option.
Multiple PipeWire outputs can be created by setting the num-outputs option in

Introduces three new structs, weston_tablet and weston_tablet_tool for the
respective devices, with the respective information as it's used on the protocol.
And weston_tablet_tool_id to track the tools of a tablet.
Note that tools are independent of tablets, many tools can be used across
multiple tablets.
The nesting on the protocol level requires a global tablet manager, a tablet
seat nested into weston_seat. The list of tablets and tools are also part of
the weston_seat.
Most functions are stubs except for the actual tablet and tablet tool
creation and removal.

This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.
See the previous commit "protocol: new screenshooter protocol" for why.
If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.

Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

This creates the color-lcms plugin that in the future will be using
Little CMS as the color matching module, processing ICC profiles, and
producing HDR tone mappings.
Right now, this new plugin is functionally equivalent to the no-op color
manager, except it already links to lcms2 and checks that the renderer
supports color operations.
Color-lcms is a libweston plugin that is loaded with explicit
weston_compositor API. This does not currently allow loading alternative
color manager plugins. External color manager plugins might be
considered in the future when the libweston APIs around color management
stabilize.
This libweston plugin uses the same build option as the old cms-static
Weston plugins, as they both need lcms2. The minimum version for lcms2
was chosen by what Debian Buster provides today and for no other reason.
This plugin intends to support the Wayland CM&HDR protocol extension and
hence sets supports_client_protocol to true. This will expose the
protocol extension to clients when it gets implemented.
