No need to update x1, x2 and y1 when merging a damage rect into a
previous one because they don't change. Melt merge_rect() into the
band compression routine as it's quite short now and convert the
boolean-based for/else construct to a more concise goto-based one.
Describe the compression logic to give a bit more context.

Previous commit ensured damage rects compression (first step) happens

Before rendering a surface, its visible region is intersected with the
damage region in global space. The resulting region is compressed
(first step) and transformed to surface space (second step) for
clipping. These steps sometimes happen twice when a paint node both
has an opaque and a translucent region. This commit makes sure the
first step happens just once.

Shell fades out and in depending on user interactions. When screen
is faded out, first interaction wakes up the shell from idle and screen
fades back in. However, this first interaction is applied to whatever
is "behind" faded screen and it may trigger unwanted actions (first
touch or mouse click on active GUI elements). Behavior is the same for
both idle and lock screen (because unlock dialog is created after the
first interaction).
Update fade animation curtain creation function to capture inputs in
order to prevent unwanted interactions within faded or locked shell.

This is not strictly necessary, because if init fails, then
weston_compositor_backends_loaded() fails, main.c will
weston_compositor_destroy() -> weston_compositor_shutdown() ->
cmclcms_destroy() which will free this. But that is very hard to track
down, so let's make the code obviously more correct.
We must also avoid cmsDeleteContext(NULL), because it will then do
something to the default cms context rather than bail out.

This does not change any behaviour, but creating complex dynamic things
was intended to be done in init() rather than color_manager_create().
Create is called from weston_compositor_load_color_manager() before
loading backends, and init is called from
weston_compositor_backends_loaded() after loading backends.
Now we assert instead of check that scope creation succeeded, because
the only way it could fail is to have small memory allocations fail, or
internal code error.

Currently we create the color profile id generator in

weston_compositor_create()/destroy().

When we are destroying the color manager, the components referencing
color profiles should have already been destroyed. We have an assert
in cmnoop_destroy() to make sure that the stock profile has refcount
equal to 1.
But we currently have an issue in Weston. While shutting down with
client surfaces alive, we may leak them. So we try to destroy
the color manager with surfaces still alive, and they may be
referencing color profiles.
We already have a workaround for this in our LittleCMS color plugin,
but we've missed that in color-noop. This fixes that, so now we don't
hit the assert anymore.
As we are already dealing with asserts in color-noop, I took the
liberty to replace the last usage of assert with our own wrapper
in this file.

wl_display_get_protocol_error() takes a pointer to interface as
parameter and may set it to NULL when the error comes from an unknown
interface.
That can happen when the client destroys the wl_proxy before calling
this function. So when the wl_display.error event comes, it will refer
to an object id that has already been marked as deleted in the
client's object map. So the protocol error interface will be set to
NULL and its id to 0.
In our test suite, expect_protocol_error() ignores such case, and
asserts that a interface != NULL is set. This commit fixes that, and
now callers are able to call expect_protocol_error() when they expect
errors from unknown objects.
In the next commit we add the color-management protocol implementation
tests, and that requires such case to work.

When using some features from LittleCMS in our CI, we are seeing some
crashes on the address sanitizer. Bumping the LittleCMS version fixes
that. So build and install a more recent version of LittleCMS on our CI.
We chose version 2.16 because it introduces the function
cmsGetToneCurveSegment(). We already make extensive use of that in our
codebase, so it is a good idea to have that on our CI as well.
Now color-curve-segments.c will start to get build on the CI, as
HAVE_CMS_GET_TONE_CURVE_SEGMENT will be true. So we also fix a minor
issue in which we were comparing int with uint in this file, what was
caught after experimenting bumping the LittleCMS version.

set such descriptions for surfaces.
We still don't support the interface to allow clients to create
image descriptions from parameters, but that should be addressed
