This way the backends will the actual outputs. And at that point the backend
knows the compositor is shutting down so it can handle this differently if
necessary.
Afterwards wet_compositor_destroy_layout() just deletes the remaining

This is adding basically a copy of alpha-blending-test.c. The difference
is that here we use ICC files to set up the output color profile, and
then test light-linear blending only. BLOCK_WIDTH is set to 1 to fit
inside the output size used by the fixture setup, which is smaller than
in the original, but does not change the results.
The test is aimed at testing how color-lcms module succeeds in
linearizing the output of different ICC output profiles. Incorrect
linearization should cause changes in blending results.
The tolerance is taken from the currently achieved error statistics
(1.40908) and rounded up a little to achieve a suitable margin.

Switch from per-channel max error tolerance to max two-norm (Euclidean
distance) error. Geometrically this means that previously the accepted
volume was a +/- tolerance cube around the reference point, and now it
is a sphere with tolerance radius.
The real benefit is simplifying the code.
The error tolerance are also changed to float. Integers cannot represent
values between 1 and 2, and the jump from 1 to 2 would have been too
much. AdobeRGB tolerance gets relaxed a bit, while BT2020 tolerance
becomes stricter. The new tolerance values are the reported achieved
two-norm max errors plus a bit of margin.
Surprisingly the sRGB case tolerances remain strictly at zero, and
that's no bug in the test.

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

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.

Many programs use this information to help position pop-ups properly, and
without it funny things happen. For example, nedit and tkinter apps will
position their menus incorrectly either all the time or after an initial
window move, firefox may position right-click pop-ups incorrectly
depending on other internal state.
https://tronche.com/gui/x/icccm/sec-4.html#s-4.1.5 has much detail on
how this should work, and the Advice to Implementors section shows that
common client practices will break in the face of our miserly handling
of ConfigureNotify events.
Instead of trying to send it only for configure requests received when a
client is in a fullscreen state, send them much more frequently.

noop-renderer needs to actually access the buffer content, to ensure
that the bad-buffer test works. This was previously done using a
volatile variable, but clang rightly pointed out that the variable
access had no effect (since the volatile stack variable was never read
from, and the source is not volatile), so 9b0b5b57dd changed it to be
explicitly marked it as unused to suppress the compiler warning.
Unfortunately suppressing the warning still leaves the compiler free to
optimise out the access.
Replace the variable decorations with actually using the result of the
read, so we can be really sure that it's never going to be optimised
away.

Our positioning of override redirect windows falls apart when an
app is on the fullscreen layer, because we end up putting its
menus and tooltips beneath it. This patch raises the special
override redirect layer to be just below things like on-screen
keyboards (and, unfortunately, above things like panels).
There is no perfect way to deal with this problem, especially
for content like tooltips that don't come with transience hints.
In some cases override redirect menus could be better placed by
using the parenting/transience information provided with them
at map time, and we should probably do that at some point, but
that would still leave us with tooltips below full screen
applications, and the need for this layer change.

Currently the idle_repaint_source is removed when the output is destroyed.
This covers the most common case: When a monitor is unplugged then the
corresponding DRM output is destroyed and not just disabled.
However, outputs can be explicitly disabled by the shell. In this case the
output is not removed and idle_repaint() may be called for a removed
output.
Remove the idle_repaint_source in weston_compositor_remove_output() to fix
this. And reset the variable to ensure that the source can be created
again.
Removing the source in weston_output_release() is now no longer necessary
since it calls weston_compositor_remove_output().
