GTK depends on the a11y infrastructure to be in place unless GTK_A11Y is
set to none. It appears that despite that, users attempt to
get around the a11y requirement without setting GTK_A11Y.
This can cause, amongst other issues, performance problems
with gtk applications. Log failure to connect to the a11y
bus.
These tests can be run manually, but are not suitable for use as an
acceptance test, so let's not make frameworks like Debian's autopkgtest
run these when they run ginsttest-runner in the most obvious way.

There are two possible interpretations of "expected failure": either
the test *must* fail (exactly the inverse of an ordinary test, with
success becoming failure and failure becoming success), or the test
*may* fail (with success intended, but failure possible in some
environments). Autotools had the second interpretation, which seems
more useful in practice, but Meson has the first.
Instead of using should_fail, we can put the tests in one of two new
suites: "flaky" is intended for tests that succeed or fail unpredictably
according to the test environment or chance, while "failing" is for
tests that ought to succeed but currently never do as a result of a
bug or missing functionality. With a sufficiently new version of Meson,
the flaky and failing tests are not run by default, but can be requested
by running a setup that does not exclude them, with a command like:
meson test --setup=x11_unstable --suite=flaky --suite=failing
As a bonus, now that we're setting up setups and their excluded suites
programmatically, the gsk-compare-broadway tests are also excluded by
default when running the test setup for a non-broadway backend.
When running the tests in CI, --suite=gtk overrides the default
exclude_suites, so we have to specify --no-suite=flaky and
--no-suite=failing explicitly.
This arrangement is inspired by GNOME/glib!2987, which was contributed
by Marco Trevisan.

By dividing the blur radius to obtain the clip radius, we may end up
with halved values that result in an overshunk clip mask. Extend this
so that we ensure to cover the last pixel.
Fixes artifacts seen with the cairo renderer in X11 when resizing
windows horizontally, a black 1px high line would be seen in the
top of the window due to these outset bounds being used in clipping.
More mysteriously, also seems to fix resize lag in the GL renderer
(also X11), if e.g. the bottom-right corner of a window is resized
diagonally in bottom-left -> top-right direction, or
bottom-right -> top-left.

By using wl_output_release(), GDK lets the compositor to clean up the
output global more nicely.
For example, currently, most compositors remove the global and then
destroy it later after N seconds expire. With this, the compositor could
experiment with destroying the output global once all its resources are
destroyed.
