The recently introduced rgb_diff_stat value dumping feature logs the
"position" where the value or error was measured. The reference value
was used as the position, but the problem with the reference value is
that it is an output value and not an input value. Therefore mapping
that back to which input values promoted the error is not easy.
Fix that problem by passing the position explicitly into
rgb_diff_stat_update(), just like it is already passed in to
scalar_stat_update().
Currently the only user simply passes the reference value as position,
because there the input value is also the reference value. This is not
true for future uses of rgb_diff_stat.

The new field in struct scalar_stat allows recording all tested values
into a file. This is intended to replace ad hoc dumping code like in
alpha-blending-test.c.

Seems it will be common to print all four min/max/avg sets of errors, so
move the printing code into a shared place.
While 0.0-1.0 is the natural range for color values, people are often
accustomed to working with 8-bit or even 10-bit pixel values. An error
of +/- 1 in 8-bit is more intuitive than +/- 0.004 in floating-point.
Hence 'scaling_bits' is added so the caller can determine the value
scaling. This will scale both the reported error numbers, and the
recorded error positions (rgb-tuples), so they are all comparable.
I'm happy to get rid of those two macros as well.

We treat the argv we pass into the compositor as its to mangle, just as
it is free to do so for POSIX argv. To support this, we stash argv away
and free the saved copy later so as to not leak.
This works perfectly, except when we never call the compositor at all,
and have no saved array to free. Make sure we free the args in this
case, which can be seen as a leak of any generated args when a test
skips on preflight checks, e.g. drm-smoke when not running in CI.

The new name better matches the contents of the test.
Currently the test creates output ICC profiles with matrix-shaper and
cLUT forms, and tests that basic color conversion from input to output
color space is correct.
The common theme in this test program is to create ICC profiles to be
used as output profiles. In the future this can include more kinds of
testing, e.g. linear blending. OTOH, this test program will always be
limited to SDR because HDR testing probably will not use ICC files.

Added cLUT profile creation to validate linearization algorithm
for DToB3 tag (direction dev to PCS). The 3DLUT is
built by using raw matrix conversion from dev to XYZ and reverse
(XYZ to device).
The test uses floating point pipeline, known as unbounded mode of LCMS.
The details are described in ICCSpecRevision_02_11_06_Float.pdf
The purpose of these new test cases is to keep the GL-renderer 3D LUT
path tested even after color-lcms and GL-renderer start using
specialized matrix-shaper paths.
These also exercise build_eotf_from_clut_profile() in color-lcms, but do
not actually verify it. These cases only test that the recovered EOTF
and its inverse produce an identity mapping together.
BT.2020 is not used in these tests, because the RGB-XYZ conversion
matrix does not stay inside [0.0, 1.0] in either direction, which would
be a problem for the 3D LUT element in the multiProcessingElement
pipelines. Handling that would have been possible, but testing with
AdobeRGB color space should suffice while keeping the test code from
being even more complicated.
roundtrip_verification() tests that we succeed in creating cms
pipelines correctly in both directions so that the resulting ICC file is
better behaved. The Weston test itself only cares about the BToD
direction.

This adds a new test helper library that depends on LittleCMS 2.
For starters, the library implements conversion from enum transfer_fn to
ICC multiProcessingElements compatible LittleCMS curve object.
That conversion allows encoding transfer funtions in ICC files and
LittleCMS pipelines with full float32 precision instead of forcing a
conversion to a 1D LUT which for power-type curves is surprisingly
imprecise.

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

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).

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.

so Meson makes sure the DSO is found.

Individual struct fields are inconvenient to index into, yet most

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

For demonstration, two simple functions in color_util.c are converted.
Unfortunately initializers need to be corrected everywhere. Field .a is

For the intersection we have a slightly different approach, what makes
the API weird. We don't save the result in the arguments, instead we
return a new array with the result.
Modify weston_drm_format_array_intersect() in order to make it similar
to the other two set operations.

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.

This fixes all ASan reported leaks in this test.
This test program has several tests named *_multiple that just run
another test function 30 times. Previously without cleanup all the
created clients would be left lingering, but now they are torn down. Ths
might cause a change in test behaviour, although that was never the
intention:
> It is intentional to run it so many times, but it is not intentional
> to run a hundred clients at a time. The problem is that currently we
> have no destroy function for client. However, the clients do not run
> simultaneously but serially, so the effect should be the same as if
> we'd destroy them (after the client finishes its body, it just 'is'
> and does nothing until the process exits)

The intention for the repeat testing is that as the Weston instance
remains from test to another, each test needs to undo its changes to the
devices. Failing to correcntly undo would accumulate devices.

Fixes all ASan reported leaks.
The manual touch release is slightly awkward as we need to open-code a
part of input_destroy() to avoid double-freeing pointer->wl_touch.

Not printing these will drop 7980 lines or roughly 350 kB from the test
logs. Now I don't have scroll through them all, and I don't have to
watch them if I run this test manually.
These prints were useful when developing the test, but we don't need
them printed in CI all the time. Printing the final count should be
enough.

Now that GL-renderer and color manager implement linear light blending
for sRGB EOTF, add a test case to verify the result is expected.
As noted in test comments, this new tests is quite powerful in ensuring
the whole linear light pipeline is working correctly with 1D LUTs in
GL-renderer. This test will even catch smashing source_lut.scale = 1.0f
and source_lut.offset = 0.0f which would result in wrong texture sample
positions for LUT data.
As the assumption is that by default content and outputs are in sRGB
color space, this test should not need fix-ups or become stale when more
color management features are implemented.
The sRGB EOTF can be found in:
http://www.color.org/sRGB.pdf (beware, typos)

Note on AMD Polaris 11 error threshold: this is quite likely due to
using fp16 format shadow framebuffer and GCN fp32 to fp16 conversion
instruction rounding mode. When using fp32 shadow framebuffer, the error
glitch is not present and the threshold could be significantly lower.

Instead of checking just the monotonicity of the blending results, this
changes the alpha-blending test to compute the reference blend result
itself and then comparing to the compositor result. This way we can be
sure that the compositor implements the exact correct formula and not
something that just looks nice, as verifying the reference images are
actually correct is hard.
The reference image is renamed to follow the fact that this is not
primarily a monotonicity test anymore. The reference image is also
redundant, but I think it has documentary value.
The #if 0'd block of code was very useful in figuring out blending
errors in a future test case, so it is included here. I have a feeling
we are going to need it again.

Refactor the alpha-blending test to allow using all three images
foreground, background, and screenshot in a future new verification
function.
This is a pure refactoring, no change in behavior.
