c68247f63b introduced a scroll multiplier,
intended to be significantly lower than the GTK 4.6 behavior but higher
than 1. However, it was _higher_ than 4.6, since 4.6 also had a permanent
1/10 multiplier in GDK, so the cited multiplier values were really 6.4 and
9.7.
We may have situations where velocity is 0/0, but are overshooting. Places where
this happens are mouse wheels, and continuous scroll that ended up still before
finish. In this situation we also want to run the animation for overshoot, so
check for the corresponding axes to also set up the kinetic scroll helper.

The expected configurability is not going to arrive yet from compositors, and
it is precipitate for GTK to gain any configurability. We do know a factor of 1
feels way too slow, and we do know a factor of page_size * pow (2 / 3) feels way
way too fast.
With the previous multiplier, gtk4-demo at its default size had a vertical textview
factor of 64.332901, and maximized on a 1920x1080 screen a factor of 97.585365.
Pick a magic multiplier that is both significantly below these values and above 1,
and stick to it.
Future work will add the configurability of smooth scroll events where it belongs.
At that point this commit may be reverted so we don't pile up on magic numbers again.

When widgets go mapped/unmapped, we repick but don't generate crossing
events. Since there could be stateful controllers that use those in
the previously picked widget (e.g. GtkEventControllerMotion), skipping
those breaks their state.
Ensure to send the relevant crossing events on every situation that
changes the pointer focus, so these controllers get a fair opportunity
to undo their state.

Even though the argument is non-nullable, GTK sometimes incurs in that
by itself by destroying the surface while the event is in flight. This
is the case of popping down a GtkDropdown. When this happens we simply
ignore the crossing event, but we should let it through instead, the
compositor did not send it in vain and we possibly still have pointer
state to undo.
Drop the surface checks, so that the event is propagated along GTK.
Following what was done for pinch/swipe events, give hold gestures their
own distinct sequence as well. Without this it was NULL, which was already
distinct to other touchpad gestures.
This delaying of the cancel event was made to avoid intermediate cancellation
for >=2fg hold gestures followed by pinch/swipe gestures, and it worked as
long as everything was considered to have the same sequence.
Since each pinch/swipe pointer gesture now gets its own sequence, this no
longer applies, nor works. This results in zoom/rotate/swipe gestures being
stuck since the sequence for the touchpad events changes mid-gesture.
Sticking to this pattern of giving touchpad gestures their own sequence,
these hold events cannot be assumed to coalesce with other touchpad gestures,
it is better to let it propagate altogether so that both the hold gesture
and the incoming gesture trigger coherent begin and end/cancel phases.
In the worst case, this results in "::begin, ::cancel, ::begin , ..." before
triggering a touchpad gesture, but the extra begin/cancel ought to be a safe
no-op in widgets.

The textbuffer test is calling into a function defined by the AT-SPI
accessibility backend. As of commit 4ddf1b70 we only build and run the
test on Linux, but the function in question isn't really
accessibility-related: it's just a serialization function.
Let people know that they will need to use GTK with the Nahimic service
disabled or OpenGL disabled or put their GTK application into the Nahimic
backlist, or try to use GLES, since there is a known issue in the Windows
nVidia graphics drivers and Nahimic that causes GL operations to fail,
causing crashes in operations such as window resizes.
This will close issue #4113--sadly, there is nothing we can do within
GTK to fix the issue.
If gtk_builder_expose_object() is called twice with the same name, it will
result in a g_critical(). This improves that situation by checking for the
object before exposing additional times.
This turns out to be handy in situations where templates are expanded
multiple times, such as application-side implementations of UI merging.
If we get an invalid TARGETS reply, we might not have a valid 'type',
which ends up as NULL and segs in the g_str_equal.
(This is probably fallout from my fix 506566b6a4, which I still
can't reproduce reliably, so the last one just moved the seg a bit
further along, and we still don't know who is sending a bad TARGETS).
This corresponds to:

C API users can keep dealing with the implicit equivalence of
GdkFileList and GSList, but language bindings have no idea that one type
is another, and none of them exposes GSList as a type anyway, so they
will need a way to construct a GdkFileList.
Instead of making GdkFileList mutable, and re-implement GSList, we only
provide a constructors pair that lets you create a GdkFileList from a
linked list or from an array.
