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.

This a new matrix inversion test written from scratch to be suitable for
running in CI: quick to run and automatically detects success/failure.
This all is a result of what I learnt while working on
https://gitlab.freedesktop.org/pq/fourbyfour
Computing the residual error with infinity norm comes straight from
fourbyfour documentation on how to evaluate matrix inversion error.
Most of the hard-coded test matrices have been generated with fourbyfour
project as well, as it contains the generator code. The matrices are
hard-coded here also to make testing faster, but primarily because the
generator code needs BLAS and LAPACK, and having those as Weston
dependencies would be far too much just for this.
Now, if someone wants to modify weston_matrix stuff, we should at least
detect matrix inversion and multiplication bugs.

This test program was useful a decade ago when weston_matrix_invert()
was being developed. It was a manual test program that ran for a certain
number of seconds and required human interpretation of numbers to see if
results were acceptable or not. Hence it was foundamentally unsuitable
for CI.
The way it generated random matrices for inversion testing was also very
naive, and it used the determinant value to determine invertability
which is completely bogus. This made it also a bad test for correctness.
Much better speed and correctness testing is implemented in
https://gitlab.freedesktop.org/pq/fourbyfour
with documented testing procedures. It has a copy of the weston_matrix
implementation.

This commit is not believed to result in any functional changes.
Signed-off-by: Daniel Stone <daniels@collabora.com>
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.

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 is probably the simplest case to demonstrate how to use
WESTON_EXPORT_FOR_TESTS.
Previously, vertex-clip test re-built vertex-clipping.c for itself. Now
it directly links in gl-renderer.so instead as that is where
vexter-clipping.c gets built into for actual use. This probably will not
work for any installed program, but luckily tests are never installed,
so Meson makes sure the DSO is found.
Unfortunately we cannot remove the definition of dep_vertex_clipping
yet, because clients/cliptest.c needs it.
This makes vertex-clip test depend on GL-renderer, but that is where the
code is really used.

Individual struct fields are inconvenient to index into, yet most
operations on a color just repeat the same for each of RGB channel.
Being able to index into RGB avoids repeating the same code for each
channel.
Alpha channel is left as separate, since it is almost never handled the
same as RGB.
The union keeps the old .r, .g and .b addressing working. The static
asserts ensure the aliasing is correct.
For demonstration, two simple functions in color_util.c are converted.
Unfortunately initializers need to be corrected everywhere. Field .a is
not explicitly initialized because it is unused in these cases.
This change should make code easier to read.
This change requires gnu99 or c11 standard. gnu99 is already the default
in top-level meson.build.

1. Use fixture_setup to set the generated by LCMS output profile based on
given chromaticities and white points. The following list of well known
chromaticities:
- sRGB
- adobe RGB
- bt2020
and white point is D65. Use INTENT_ABSOLUTE_COLORIMETRIC to avoid BPC.
Input profile is always sRGB and it is used internally by Weston as
stock profile.
2. Use these hardcoded matrixes as part of pipeline 1DLUT->3x3->1DLUT.
The diagnostic code to retrieve the transform matrix is availble into
test in the comments. The conversion matrixes generated for the
following cases:
- sRGB to sRGB (unity)
- sRGB to adobeRGB
- sRGB to BT2020
3. Compare GPU shaders(gl texture3D) vs manual pipeline calculation
Use different max tolerable error per transform.
There are comments how number of points in 3DLUT is related to tolerance.
Tolerance depends more on the 1D LUT used for the inv EOTF than
the tested 3D LUT size: 9x9x9, 17x17x17, 33x33x33, 127x127x127.
4. Enable build matrix-shaper test if color-management-lcms is enabled.

35/36 ivi-shell-app TIMEOUT 122.51s
ERROR: Job failed: execution took longer than 5m0s seconds
That is hitting both kinds of timeouts at the same time: the per-test
timeouts, and the CI job total timeout.
That run seems to have had a particularly ill fortune, as a simple retry
finished the same job in 2 minutes, and the longest running test took
only 24 seconds.
Nevertheless, by Daniel Stone's suggestion let's bump both timeouts:
- the per-test timeout to 120 seconds, which with the multiplier in CI
goes up to 8 minutes
- the job timeout for all build related jobs to 15 minutes
The timeout for tests_standalone is not bumped as we are not adding
significant amounts of new tests there.

For the intersection we have a slightly different approach, what makes

return a new array with the result.

Our core test structure is 36 bytes wide. Declaring it with a 32-bit
alignment should thus stripe it to 64 bytes. For some reason, clang+lld
lays them out with a 96-byte stride within the section (does it want an
entire 32-bit word when building with ASan?), getting the code wildly
confused when it tries to step through the structures.
So we could fix all our tests to avoid the fragile section dance, or we
could just waste another 4 bytes per test definition by bumping the
alignment up to 64 bytes, which seems to do enough to magically accord
with what clang+lld+ASan expect.
