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)
https://www.w3.org/Graphics/Color/srgbhttps://www.khronos.org/registry/DataFormat/specs/1.3/dataformat.1.3.html#TRANSFER_SRGB
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.

Initialize LittleCMS and use it to generate the sRGB EOTF and inverse
curves. Use these curves to define the blending color space as optical
(linear) sRGB by assuming that both content and output color spaces are
sRGB.
As a consequence, this causes Weston to do "gamma correct blending", as
in, blend in light linear space which should avoid distorting colors in
alpha gradients, when color-lcms is active.
This makes use of the 3x1D LUT support added in gl-renderer earlier, and
shows how the color manager is responsible for re-using existing color
transformation objects.

This makes weston_color_transform object be able to express
three-channel one-dimensional look-up table transformations. They are
useful for applying EOTF and EOTF^-1 mapping, or, gamma curves. They
will also be useful in optimizing a following 3D LUT tap distribution
once support for 3D LUT is added.
The code added here translates from the lut_3x1d fill_in() interface to
a GL texture to be used with SHADER_COLOR_CURVE_LUT_3x1D for
weston_surfaces.
It demonstrates how renderer data is attached to weston_color_transform
and cached.
GL_OES_texture_float_linear is required to be able to use bilinear
texture filtering with 32-bit floating-point textures, used for the LUT.
As the size of the LUT depends on what implements it, lut_3x1d fill_in()
interface is a callback to the color management component to ask for an
arbitrary size. For GL-renderer this is not important as it can easily
realize any LUT size, but when DRM-backend wants to offload the EOTF^-1
mapping to KMS (GAMMA_LUT), the LUT size comes from KMS.
Nothing actually implements lut_3x1d fill_in() yet, that will come in a
later patch.

This adds shader support for using a three-channel one-dimensional
look-up table for de/encoding input colors. This operation will be useful
for applying EOTF or its inverse, in other words, gamma curves. It will
also be useful in optimizing a following 3D LUT tap distribution once
support for 3D LUT is added.
Even though called three-channel and one-dimensional, it is actually
implemented as a one-channel two-dimensional texture with four rows.
Each row corresponds to a source color channel except the fourth one is
unused. The reason for having the fourth row is to get texture
coordinates in 1/8 steps instead of 1/6 steps. 1/6 may would not be
exact in floating- or fixed-point arithmetic and might perhaps risk
unintended results from bilinear texture filtering when we want linear
filtering only in x but not in y texture coordinates. I may be paranoid.
The LUT is applied on source colors after they have been converted to
straight RGB. It cannot be applied with pre-multiplied alpha. A LUT can
be used for both applying EOTF to go from source color space to blending
color space, and EOTF^-1 to go from blending space to output
(electrical) space. However, this type of LUT cannot do color space
conversions.
For now, this feature is hardcoded to off everywhere, to be enabled in
following patches.

Always when supported, make the fragment shader default floating point
precision high. The medium precision is roughly like half-floats, which
can be surprisingly bad. High precision does not reach even normal
32-bit float precision (by specification), but it's better. GL ES
implementations are allowed to exceed the minimum precision requirements
given in the specification.
This is an advance attempt to avoid nasty surprises from poor shader
precision.

Add a new shader requirements bit input_is_premult which says whether
the texture sampling results in premultiplied alpha or not. Currently
this can be deduced fully from the shader texture variant, but in the
future there might a protocol extension to explicitly control it. Hence
the need for a new bit.
yuva2rgba() is changed to produce straight alpha always. This makes
sample_input_texture() sometimes produce straight or premultiplied
alpha. The input_is_premult bit needs to match sample_input_texture()
behavior. Doing this should save three multiplications in the shader for
straight alpha formats.

The DRM backend uses changes in the cursor view memory address and
surface damage to detect when it needs to re-upload to a cursor plane
framebuffer.
However, when a cursor view is destroyed and then recreated, e.g., when
the pointer cursor surface is updated, the newly created view may have
the same memory address as the just destroyed one. If no new cursor
buffer is provided (because it was attached, committed and used
previously) when this address reuse occurs, then there also isn't any
updated surface damage and the backend doesn't update the cursor plane
framebuffer at all.
To fix this issue utilize the destroy signal to track when the cursor
view is destroyed, and clear the cached cursor_view value in drm_output.
After clearing the cached value, the next cursor view is always
considered new and thus uploaded to the plane properly.

This creates the FP16 shadow framebuffer automatically if the color
transformation from blending space to output space is not identity and
the backend does not claim to implement it on the renderer's behalf.
That makes the weston_output_set_renderer_shadow_buffer() API and
use-renderer-shadow weston.ini option obsolete.
To still cater for the one test that needs to enable the shadow
framebuffer in spite of not needing it for color correct blending, the
quirk it uses now also forces the shadow.

Trying to support GL ES 2.0 + extensions along with GL ES 3.0 for better
control is becoming too complicated fast. In this patch you see the
GL_RGBA vs. GL_RBA16F and GL_HALF_FLOAT vs. GL_HALF_FLOAT_OES paths.
More such cases will come, e.g. GL_RED_EXT vs. GL_R32F.
Make things simpler and require GL ES 3.0 +
GL_EXT_color_buffer_half_float for all color management related
functionality. If one doesn't have GL ES 3.0, all you lose is color
management.
Also, all extensions needed by color transformation operations are
gathered under one boolean flag instead of having a flag per extension,
again for simplicity.
This makes the GL ES extension handling much easier.

If we make EGL_NO_CONTEXT current, all following GL calls are
no-ops. This will be a problem when gl-renderer introduces
gl_renderer_color_transform containing GL textures and needs to destroy
them when weston_color_transform is destroyed. Mesa would print the the
warning that glDeleteTextures is no-op.
To fix this, keep our GL context current when destroying a GL output.
In case EGL_KHR_surfaceless_context is not available, we must use
dummy_surface.

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.

This is needed when the compositor produces any content internally:
- the lines in triangle fan debug
- the censoring color fill (unmet HDCP requirements)
Solid color surfaces do not need this special-casing because
weston_surface is supposed to carry color space information, which will
get used in gl_shader_config_init_for_view().
This makes sure the internally produced graphics fit in, e.g on a
monitor in HDR mode.
For now, just ensure there is an identity transformation. Actual
implementations in GL-renderer will follow later.

This is needed when drawing anything internal directly to an output,
like the borders/decorations in a nested compositor setup. This makes
the assumption that the internal stuff starts in sRGB, which should be
safe. As borders are never blended with other content, this should also
be sufficient.
This patch is a reminder that that path exists, rather than a real
implementation. To be implemented when someone needs it.

This is the blending space to monitor space color transform. It needs to
be implemented in the renderers, unless a backend sets
from_blend_to_output_by_backend = true, in which case the backend does
it and the renderer does not.
The intention is that from_blend_to_output_by_backend can be toggled
frame by frame to allow backends to react to dynamic change of output
color profile.
For now, renderers just assert that they don't need to do anything for
output color transform.

See: https://gitlab.freedesktop.org/wayland/weston/-/issues/467#note_814985
This starts building the framework required for implementing color
management.
The main new interface is struct weston_color_manager. This commit also
adds a no-op color manager implementation, which is used if no other
color manager is loaded. This no-op color manager simply provides
identity color transforms for everything, so that Weston keeps running
exactly like before.
weston_color_manager interface is incomplete and will be extended later.
Colorspace objects are not introduced in this commit. However, when
client content colorspace and output colorspace definitions are
combined, they will produce color transformations from client content to
output blending space and from output blending space to output space.
This commit introduces a placeholder struct for color transforms,
weston_color_transform. Objects of this type are expected to be heavy to
create and store, which is why they are designed to be shared as much as
possible, ideally making their instances unique. As color transform
description is intended to be generic in libweston core, renderers and
backends are expected to derive their own state for each transform
object as necessary. Creating and storing the derived state maybe be
expensive as well, more the reason to re-use these objects as much as
possible. E.g. GL-renderer might upload a 3D LUT into a texture and keep
the texture around. DRM-backend might create a KMS blob for a LUT and
keep that around.
As a color transform depends on both the surface and the output, a
transform object may need to be created for each unique pair of them.
Therefore color transforms are referenced from weston_paint_node. As
paint nodes exist for not just surface+output but surface+view+output
triplets, the code ensures that all paint nodes (having different view)
for the same surface+output have the same color transform state.
As a special case, if weston_color_transform is NULL, it means identity
transform. This short-circuits some checks and memory allocations, but
it does mean we use a separate member on weston_paint_node to know if
the color transform has been initialized or not.
Color transformations are pre-created at the weston_output
paint_node_z_order_list creation step. Currently the z order lists
contain all views globally, which means we populate color transforms we
may never need, e.g. a view is never shown on a particular output.
This problem should get fixed naturally when z order lists are
constructed "pruned" in the future: to contain only those paint nodes
that actually contribute to the output's image.
As nothing actually supports color transforms yet, both renderers and
the DRM-backend assert that they only get identity transforms. This
check has the side-effect that all surface-output pairs actually get a
weston_surface_color_transform_ref even though it points to NULL
weston_color_transform.
This design is inspired by Sebastian Wick's Weston color management
work.

A following patch will need the paint node in
gl_shader_config_init_for_view() for color transformations.
While passing the paint node through, rename the functions to be more
appropriate and get surface/view/output from the paint node.
This is a pure refactoring with no functional change.
