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.
After commit 447bc18c48 EGL on X11 broke.
But the handling of the GL context also was quite awkward because it was
unclear who was responsible for ensuring it got reset.
Change that by making gdk_gl_context_clear_current_if_surface() return
the context (with a reference because it might be the last reference) it
had unset, so that after changing EGL properties the code that caused
the clearing can re-make it current.
This moves the responsibility to the actual code that is dealing with
updating properties and frees the outer layers of code from that task.
And that means the X11 EGL code doesn't need to care and the code in the
Wayland backend that did care can be removed.

This essentially reverts the changes from
c230546a2c but implies new semantics.
Namely, surface-attached contexts can now be bound to EGL_NO_SURFACE if
the windowing system isn't ready yet.
It is the task of the windowing system to make sure the context is
properly rebound when the contents become available.
We ensure this by checking in begin_frame() if we created the EGL window
and if we did, we make_current(). This works because creating the EGL
window creates the EGL surface and that does a clear_current(), so this
is always going to have the desired effect of re-making the current
context.
It is very convoluted though.

The default implementation of unselect_all calls
set_selection, which SingleSelection does not have
an implementation for (it's unclear what it would
do with multiple selections). Add a straightforward
implementation for unselect_all.
Commit d58b545f fixed a double counting of value size, but didn't check
whether that actually looked great. It doesn't.
Because the slider has negative margins, we need to add margin to the
value if it's on a side with no marks. If it is on a side with marks,
the scale will make it touch the marks. We therefore apply a mark's size
of margin to have the value be in the same place, with or without marks.
The texture ID is not deleted on dmabuf export; a copy is made, the
GskGpuImage retains ownership.
However when doing GL export, the texture *does* take ownership, so we
need the stealing semantics for that case.
We do this because:
a) The parent class (GdkGLContext) already stores the paint regions of
previous frames, no need to do the same.
b) The painted region passed to end_frame () includes the backbuffer's
damage region, so it's not really what we want.
This also fixes a leak of cairo_region_t that I introduced by mistake
in !7418
The measured size of the range already includes borders that the scale
calculates. This includes the drawn value. So in the measurement of
scale, the size of the value shouldn't just be added to the size of the
scale, as then the size is effectively added twice.
To fix this, we first measure the minimum size of the range. Then, we
determine the minimum size of our scale. Only then do we set the minimum
size to maximum of those two values.
If both marks are set on top, and the value is drawn on top, the value
should be drawn outside the marks for a horizontal scale.
Currently, that order is incorrect, with the marks shifted up and the
value drawn between the slider and the marks.
This fixes that order.
We can get the position of the trough from the parent GtkRange class,
and can therefore align directly to that. There is no need to add
symmetry, which can always be added in CSS if needed.
Fixes#5171, #6639
This only makes the value allocation logic easier to understand, but
doesn't change anything, apart from not mixing integer and floating
operations anymore which can give a warning under some compiler
settings.
This reverts commit 2799632c02, reversing
changes made to 154035e76f.
That MR tried to fix#5171, but by doing a forced symmetry it introduced
another issue for users on Libadwaita, see #6639.
The logic can be much simplified, as the next commits show.
CI is hitting various limits after we started out with 32. In
particular, the default runners hit 90s test timeouts.
And the asan runner runs into max threads limits, so reduce that one to
4 tests max.
This is a test balloon tests that use /dev/udmabuf to produce
dmabufs that we can use in ci, even if we don't have a GPU.
Currently, the tests we can do are somewhat limited, since mesas
software renderers don't support dmabufs yet.
Instead of every test spawning their own dbus, make the tests share the
same server, just like they share their own compositor.
This should speed up things a bit and avoid weird interactions when
multiple dbus processes exist.
