While the --backend parameter looks like it takes a file name, it really
is selected from a list of supported strings that are then funneled
through a translation to enum weston_compositor_backend [1].
Because all backend parameters are of the form "...-backend.so", and
writing "--backend=...-backend.so" is boring, allow the --backend option
to match the backend name without "-backend.so" suffix instead.
For example, this allows to use "--backend=headless" instead of
"--backend=headless-backend.so".
Update help text and documentation. Keep the old way working for
backwards compatibility.

With commit 'Move libweston-desktop into libweston' we've moved out
libweston-desktop DSO into libweston. Move also the header to
libweston/desktop.
This removes removes the libweston-desktop pc file and bumps libweston

It's not really useful to have libweston without libweston-desktop. It's
also very little code.
Merging both into the same DSO will allow us to cut out a bunch of

Before this change the drm-backend in Weston did the work of parsing DRM
blobs in order to query IN_FORMATS data, if available. This is also the
case for other DRM/KMS clients that use IN_FORMATS (i.e. X).
libdrm 2.4.108 with e641e2a6 ("xf86drm: add iterator API for DRM/KMS
IN_FORMATS blobs") introduced a dedicated API for querying IN_FORMATS data.
Bump the minimum required version to 2.4.108, stop parsing IN_FORMATS in
Weston and start using DRM iterators. In addition, remove fallback code for
libdrm <2.4.107.

This reverts commit 1618697dc3.
The original commit was a workaround for
https://gitlab.freedesktop.org/mesa/mesa/-/issues/2219 which was fixed
in Mesa:
- c7617d8908a970124321ce731b43d5996c3c5775 released as 20.1.0-rc1
- a0e6341fe4417e41cda0b19e4fa7f8bbe4e1dba1 released as 19.3.5
- f27e5d9df5bc9c85d45c2cb1f2a4997b453365fe released as 20.0.0
This workaround should not be necessary anymore, we don't use it in our
CI, and it was manual to begin with. Therefore remove it.

With commit e825fe38, we no longer display the pointer if no movement is

shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.
This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.
shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.
Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.
In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).
This commit contains no functional changes to any observable code.

Moving forward we're going to be supporting libseat and logind as our
only launchers. We're doing this to reduce our maintenance burden,
and security impact.
Libseat supports all our existing use cases, and seatd can replace
weston-launch so we no longer have to carry a setuid-root program.
This patch removes weston-launch, and launcher-direct, leaving only
libseat and logind.

These formats are useful because they are often easier to produce
on CPU than half-float formats, and abgr16161616 has both >= 10bpc
color channels and adequate alpha, unlike abgr2101010.
The 16-bpc textures created from buffers with these formats require
the GL_EXT_texture_norm16 extension.
As WL_SHM_FORMAT_ABGR16161616 was introduced in libwayland 1.20,
update Weston's build requirements and CI.
The formats also needed to be registered in the pixel format table,
and defined in a fallback path if recent libdrm is not available.

This patch adds the tooling for incorporating files as C data, so that
files can be built into the binaries. The tool is in Python to avoid
adding extra dependencies like xxd.
xxd.py is copied from Mesa as-is, from commit
b729cd58d76f97f3fc04a67569535ee5ef2f5278 (master branch on 2021-01-26),
a.k.a 21.0-branchpoint-635-gb729cd58d76.
Moving the GLSL vertex shader into a separate file is not that
interesting, the purpose of this commit is to provide a simple
demonstration of the tooling. The real benefits come in a following
patch where the fragment shaders are re-written and externalized.

fine. Mesa does that too. Bump the requirement to 0.52.1 which is the

Ubunut Xenial is the only mentioned distribution that does not provide a
libdrm new enough. I think that is fine to drop now, 2016 was a good
while ago.
Libdrm 2.4.95 also introduced DRM_CLIENT_CAP_ASPECT_RATIO,
DRM_MODE_PICTURE_ASPECT_64_27, DRM_MODE_PICTURE_ASPECT_256_135.
The fallback definitions for the above are dropped.

kiosk-shell is fullscreen shell for apps that use the xdg-shell
protocol. The goal is to make life easier for people shipping embedded
devices with simple fullscreen shell requirements, and reduce the
proliferation of desktop-shell hacks.
Top level surfaces are made fullscreen, whereas dialogs are placed on
top in the center of the output and retain their natural sizes. Dialogs
can be moved and (un)maximized, but resizing is currently not supported.
An app can be directed to a particular output by populating the
"app-ids" field with the app's XDG app id, in the relevant
"[output]" section in the weston config file.
