The standard style of LCOV HTML reports is a bit harsh to look at. This
commit replaces it with a new one.
The new CSS was written from scratch by looking at the HTML source code
of a generated LCOV report. The original gcov.css file was not used.
The color scheme is neutral, trying to avoid a Christmas tree effect.
The colors are intended to be calm while also distinguishable, and not
hamper text readability.
The font lists were taken from Gitlab with the hope that it will blend
in a little better when viewing from MR artifacts.

In some situations, like positioning a sub-surface that exceeds the
output's dimensions we would adjust the plane state dimensions to some
lower values to that of the buffer. That would ultimately trip the cursor
update function because the buffer itself actually exceeds the maximum
size/dimension of the cursor.
The plane state destination co-ordinates is the area of the view which
is visible on the output, which in some situations, would actually be
smaller than the original buffer dimensions (making it so that it will
pass the cropping/scaling check), but depending on of
how large is the surface buffer, it would tripping the assert wrt to
cursor width/height dimensions.
This hasn't been seen so far due to the fact that until recently we had
a cursor surface that always reached the cursor plane and that was
already being set-up by default (with desktop-shell, which is no longer
the case), and also because kiosk-shell, which doesn't set-up a cursor
surface, was not available.
This adds a check to skip placing the view in the cursor plane if the
buffer dimensions exceed the cursor permitted width/height.

fixes issue #484 (race condition with message to/from weston launch)
The race condition occurs after weston sends the WESTON_LAUNCHER_OPEN
message to weston-launch. The race is between when weston-launch replies
with the fd handle versus weston-launch sending an activation message. If
weston-launch sends an activation message before sending the fd handle,
then weston will be in an invalid state.
To fix this, I modified the fd handle reply that weston-launch sends to
include a message id at the beginning, which I called
WESTON_LAUNCHER_OPEN_REPLY. Along with this, weston now inspects the
first part of any reply to determine whether it is an activation message
or a reply to the OPEN message. In the newly handled case that it's an
activation message, it tracks whether the latest result is a deactivate
message and stores it in a flag to be handled once the open function has
completed.

This patch gathers all values to be loaded to shader uniforms into a new
struct gl_shader_config along with texture target and filter
information. Struct gl_shader becomes opaque outside of gl-shaders.c.
Everything that used or open-coded these are converted.
The aim is to make gl-renderer.c easier to read. Previously, uniform
values were loaded up in various places, texture units were set up in
one place, textures were bound into units in different places. Stuff was
all over the place.
Now, shader requirements and associated uniform data is stored in a
single struct. The data is loaded into a shader program in one function
only.
That makes it easy for things like maybe_censor_override() to replace
the whole config rather than poke only the shader requirements. This may
not look like much right now, but when color management adds more
uniforms and even hardcoded color need to go through the proper color
pipeline, doing things the old way would become intractable.
Similar simplification can be seen in draw_view(), where the RGBA->RGBX
override becomes more contained. There is no longer a need to "pre-load"
the shader used by triangle fan debug. Triangle fan debug no longer
needs to play tricks with saving and restoring the current shader.
The real benefit of this change will probably come when almost all
shader operations need to take color spaces into account. That means
filling in gl_shader_config parts based on a color transformation.
This is based on an idea Sebastian already used in his Weston color
management work.

This used a cargo-culted form of the ACTION check. Kernel is allowed to
invent new ACTIONs and IIRC there are already actions like bind and
unbind.
Udev events before rule processing always start with a clean property
list. This means that if you only match ACTION==add to add some value to
the event, then that value will not be present for ACTION==bind. Udev
event consumers do not accumulate values, so inconsistent value setting
may confuse them.
Therefore one needs to match ACTION!=remove, not ACTION==add|change, to
keep the device properties consistent for every event. It doesn't hurt
to set them on remove either, but it's a habit to try to avoid
processing when not strictly needed.

This should not be necessary, but my testing with fd.o Gitlab 13.9.1
shows this is needed. Otherwise the coverage markings will not appear in
a MR diff view.
Apparently Gitlab has some problem with 'filename' attribute containing
"../" in Cobertura XML files, even when that does result in a correct
path. Or maybe the problem is is with the <source> path referring to the
build dir which from Gitlab perspective does not exist in the project,
even though builddir/../ is a good path.
This sed hack removes the "../" part and the last element in the
<source> path correspondingly.

Nowadays Gitlab has some Cobertura support itself:
https://docs.gitlab.com/ee/user/project/merge_requests/test_coverage_visualization.html
lcov is needed for the HTML report, gcovr is needed for the Cobertura
report. 'ninja clean' must be removed, otherwise it deletes the coverage
files before they are analysed.
Seeing the test suite code coverage is really interesting. It can guide
designing tests. If Gitlab MRs show the coverage in diff view, it shows
if new code actually gets executed in CI.

This adds a heuristic for freeing shader programs that have not been
needed for a while. The intention is to stop Weston accumulating shader
programs indefinitely, especially in the future when color management
will explode the number of possible different shader programs.
Shader programs that have not been used in the past minute are freed,
except always keep the ten most recently used shader programs anyway.
The former rule is to ensure we keep shader programs that are actively
used regardless of how many. The latter rule is to prevent freeing too
many shader programs after Weston has been idle for a long time and then
repaints just a small area. Many of the shader programs could still be
relevant even though not needed in the first repaint after idle.
The numbers ten and one minute in the above are arbitrary and not based
on anything.
These heuristics are simpler to implement than e.g. views taking
references on shader programs. Expiry by time allows shader programs to
survive a while even after their last user is gone, with the hope of
being re-used soon. Tracking actual use instead of references also
adapts to what is actually visible rather than what merely exists.
Keeping the shader list in most recently used order might also make
gl_renderer_get_program() more efficient on average.
last_repaint_start time is used for shader timestamp to avoid calling
clock_gettime() more often. Adding that variable is an ABI break, but
libweston major has already been bumped to 10 since last release.

cbdiv = 1.772;
M = [ rf, gf, bf ;
-rf / cbdiv, -gf / cbdiv, (1 - bf) / cbdiv;
(1 - rf) / crdiv, -gf / crdiv, -bf / crdiv ];
YCbCr = [ 'Y'; 'Cb'; 'Cr' ];
RGB = [ 'R'; 'G'; 'B' ];
eq = [ ' '; '='; ' ' ];
l = [ ' [ '; ' [ '; ' [ ' ];
r = [ ' ] '; ' ] '; ' ] ' ];
mat = [
sprintf('%9f %9f %9f', M(1,:));
sprintf('%9f %9f %9f', M(2,:));
sprintf('%9f %9f %9f', M(3,:));
];
[ l YCbCr r eq l mat r l RGB r ]
R = inv(M);
mat = [
sprintf('%9f %9f %9f', R(1,:));
sprintf('%9f %9f %9f', R(2,:));
sprintf('%9f %9f %9f', R(3,:));
];
[ l RGB r eq l mat r l YCbCr r ]
