When prepare_gl fails in the right way (or the wrong way?), we
end up creating the leader window twice, and as a side effect,
creating two instances of the "Virtual core pointer" device, which
is bad news for grabs.

Keep a hard copy of the widget event controllers to handle state
changes across, and check for controllers that might have been detached.
This makes us:
- Tiptoe over controllers that might have been removed directly or
indirectly as a result of a signal emitted here, which is great and
fixes possible crashes.
- Ignore new controllers that might have been added in the handling
of these signals, which is fair enough since these controllers did
not handle any input related to the state change.

Call wl_surface_offset in end_frame to apply the offset for drag
surfaces. This matches what the GL draw context already does, and
it fixes drag surfaces jumping at the beginning of the drag.

On GTK's official upstream CI, all Linux runners are meant to have
/dev/udmabuf available, so this should pass. On developer machines or
downstream build environments, this can't be guaranteed (not all kernel
configurations offer that device, and on those that do, an autobuilder
might not have access to it) so make it possible to skip this with
`--no-suite=needs-udmabuf`.
Any future tests that rely on /dev/udmabuf (as opposed to using it for
optional better coverage if available, like replay-node does) can be
aded to the same suite.

This function is used to sort a GPtrArray of "pointers" which are
actually GINT_TO_POINTER (id), so a and b are pointers to pointer-sized
quantities.
Previously it was assuming that both were int-sized quantities,
dereferencing them to get the first sizeof(int) bytes, and then
redundantly casting those bytes to int. However, on a 64-bit big-endian
platform, the first few bytes of a larger-than-int quantity are the
most significant part, in practice 0, causing an out-of-bounds array
access and a crash. This was visible in the
`gtk:css / parser variables.css` automated test.

Previously this code assumed that if we have an int stored in a hash
table via GINT_TO_POINTER, we can retrieve the pointer value and treat
its first sizeof(int) bytes as an item to append to a GArray of int.
However, on a 64-bit big-endian system, the first sizeof(int)
bytes of the pointer will be zero, which is not a valid ID for a
GtkCssCustomPropertyPool, causing an out-of-bounds array access and
a crash. This was visible in the `gtk:css / style` automated test.

This more closely matches the spec. This is an API break, however the
atspi backend already assumed that this was a list, and would throw
criticals whenever this relation was set. Therefore it can be assumed
that this relation was not previously in active use.
Event listeners can register themselves multiple times, and deregister
themselves as well. We need to remove an event listener only if it
dropped all its events.
Assistive technologies using AT-SPI typically register themselves on the
accessibility bus through the org.a11y.atspi.Registry.RegisterEvent
method, which will emit the EventListenerRegistered signal. We can use
that signal (and its corresponding EventListenerDeregistered sibling) to
know whether there is at least an AT on the other side of the
accessibility bus.
This requires adding infrastructure to generate per-test data, so that
the random clip rect can be computed and reused for both test and
reference generation.
So add this infrastructure.
... and port the colorflip test.
This is so we can factor out generic parts of the code. This allows
making changes easier to those parts, like if we want to introduce
rules for what colorstates and memory depths to do diffs in.
We switched to using the Unicode (UTF-16) versions of the Windows API by
default, so we also obtain the display name in UTF-16 form as well.
This updates the implementation in the Windows backend so that we
properly acquire the names that we need in UTF-16, and then convert the
results to UTF-8, which is what we use in GTK/GLib.
When comparing textures, always pick the colorstate from the reference
texture. This allows us to define what color state we expect.
For now, there's no check that the color states are equal, because they
don't really have to be as long as the pixels are.
Always pick the color state from texture1 and download the data and
generate the diff in that color state.
That now means the order of the 2 arguments matters.
I first tried porting everything to float, but it turns out that that
makes a compare-render run (with all 1520 tests succeeding) 9s slower
so I decided to keep the existing U8 code.
A side benefit is that saving the diff to PNG will continue creating
U8 PNGs.
We use the renderer to create the reference for the rotate test by
applying the same rotate transform to the reference image instead of the
tested node.
This is somewhat suboptimal because they run very similar codepaths, but
this method works with high bit depth content and different colorstates
This concludes the port away from gdk-pixbuf and means that all rendered
content and reference images can now use high bit depth and colorstates.
