When a window is closed, Weston will, by default, run a fade out animation and
defer destroying the underlying surface until it completes. However, if the
compositor is sleeping, and therefore not rendering any frames, this animation
will *never* complete. Therefore, if windows are repeatedly created and
destroyed while in sleep mode, these surfaces will keep accumulating, and since
the buffers attached to them may be backed by an fd, eventually the ulimit will
be reached resulting in a potential crash or other errors.
This can be demonstrated repeatedly launching and killing an X11 application
with Xwayland running.
while true; do xterm & pid=$!; sleep 0.5; kill $pid; done
As soon as the compositor goes to sleep, one can observe a steadily growing
list of dmabufs in the output of lsof.
As a fix, desktop_surface_removed should check whether the compositor is active
before kicking off the fade animation. If it is not, it should instead drop the
extra reference taken in desktop_surface_committed and then destroy the surface
immediately.

And ultimately, fail to start when there are no input devices on the
system. Patchs adds consistency to touch/pointer initialization to
return -1 in case same thing happens.
Further more, when the device is not created we can't assume to retrieve
a valid one from a libinput_device so guard against it. This takes care of
hot-plugging situations when we couldn't create the (keyboard) device,
or when removing it.

Some graphics drivers (currently at least VMware and AMD) will give a 0
timestamp for the atomic mode flip completion event when turning off
the display. This causes us to trip an assertion in
weston_output_frame_finish() because the clock jumps backwards, which
isn't a condition the presentation feedback code should be dealing with.
This is a good assertion and we'd like to keep it. And there's some
expectation that this is buggy behaviour in the graphics drivers that will
be fixed at some point.
Pragmatically speaking though, there's nothing productive we can do with a
correct timestamp for the display shutdown. So let's just flag the
event sent for DPMS off as invalid so presentation feedback doesn't have
to worry about it, and the assert doesn't fire.

As observed on some platforms, importing known DMA buffers can cause
failures, leading to an attempt of destroyng an EGL image not set. This patch
resets the num_images such that loop becomes inert when destroying the
DMA buffer, and avoids passing an egl image to it.
The initial import doesn't have this issue as it sets the num_images in
case it succeeds. This also corrects the assumption that the num_images
were 0 at that point which, if the initial import succeded, was actually set
to 1.

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

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.
