Recommend that scope implementations should fall
back to or derive from GtkBuilderCScope in order
to not lose GTK's type-guessing machinery.

Nested async calls are always a challenge.
Hopefully, things are straightened out now,
and we report GTK_DIALOG_ERROR errors for
the cases we care about.
If the parent window of the button gets destroyed
while the dialog is open, we cancel the async op,
but we need to be a little more careful about not
stepping on glass.

Determine the location to save testcases in dynamically,
trying first a GTK_SOURCE_DIR environment variable
and then the current directory as the GTK source dir,
ultimatively falling back to just saving in the current
directory.
This avoids leaking details of the build environment
into the produced artifacts and should make GTK builds
more reproducible.

The header in GtkColumnView has multiple event handlers
there is a ::pressed handler in GtkColumnView for
resizing the columns in CAPTURE as well as a motion
and drag controller. The ::release handler is in
GtkColumnViewTitle. We can't claim the event in the
existing handlers because then the ::release handler will
never get called. Currently, however, all clicks get propagated
to the ColumnView from the header which can be problematic.
Since we don't usually want the clicks from the header
handled on the view, claim it in the BUBBLE phase.

Currently, the GdkSurfaceX11 implementation relies that the upper
layers hid the surface before destruction, and that no
GdkSurfaceClass.compute_resize happened between them. If these
circumstances happened, there would be a compute_size timeout left
dangling after the surface got destroyed, poking at incorrect data
later on. Something that looks like this was reported in the
recent mutter-x11-frames "SSD frames server":

It perhaps makes sense to warn in these situations, but either way
it sounds like gdk_surface_x11_finalize() could enforce the correct
behavior by ensuring there is no dangling timeouts/data. This commit
does that.
Active state is handled by main now. It appears that listitem and
treeexpander handled it manually (probably before main did). This
is unnecessary now, so let's remove it.
If the anchor is below the expanded item, the expanded item will
go out of view if there are sufficient children items. This is not
ideal, so make sure to scroll to the item to ensure it remains in
view.
With the introduction of the hide-expander property, I noticed that
the active state would persist in many cases because the release
signal was never emitted. In gtk3 tree expanders, expanded
on release. gtk4 expanded on press to match window explorer.
Per irc chat, the designers didn't have a strong preference
for press or release. In order to keep consistency and
fix this bug, let's move back to release.
