Check that the touchpad gesture event has a matching number of fingers before
updating the GtkGesture point tracking, instead of afterwards. Avoids pointless
tracking of these touchpad events when we know beforehand that the gesture
will never be activated by the touchpad events.

Doing clever things with objcopy is faster and seems to be reliable on
x86_64 Linux, but also doesn't work on all toolchains and architectures:
in particular, Debian has had trouble with this on arm and mips.
In a distro build environment where we are compiling all of GTK every
time, the cost of potentially unreliable builds is higher than the cost
of using slower but more conservative GResource embedding.

Some of the X keyboard layouts use compose
sequences of length one to make individual
keys generate multiple Unicode characters.
To support this use case, change the index
part of the table format to also include
an offset for length 1. Bump the table
version to indicate this change.

For some of the a11y states, calling gtk_accessible_reset_state
can change the type of the state value from boolean or tristate
to undefined.
Handle that, instead of throwing criticals.

When the IM commands the GtkText to delete text, the cursor position
would change, and so would the surrounding text. Reset the IM context
so that these updates are properly picked up by the IM.
Fixes backspace key behavior in the GNOME Shell OSK, since that relies
on the surrounding text being properly updated for the next iteration.

Resetting the IM on IM updates is too eager and indeed the simple
IM context doesn't like that this happens in the middle of dead
key handling.
We however want to reset the IM after actual text buffer changes
(say, a committed string) moved the cursor position, altered the
surrounding text, etc. So that the IM implementation does know to
update its state.
Since there is going to be an actual IM reset anyways, it does
no longer make sense to try to preserve the old priv->need_im_reset
status during commit handling.

Update the label size request when setting the digits property
by calling the update_label_request () util function.
That util function works by measuring the size request of the
label with the lower and upper values of the adjustment, then
taking the max. That way the size requisition is constant
regardless of the actual displayed value.
Since the util function internally works by setting the text
of the label, let it also set the text at last by taking in
account the current adjustment's value. Most of its callers
do that anyway.

If you've begun a user action and call `gtk_text_buffer_set_text`, you
get an unexpected warning:
```
Gtk-WARNING **: Cannot begin irreversible action while in user action
```
which can be fixed by doing the delete/insert yourself. But this is not
documented as occurring, so document it.
We want to claim the event sequence in the click gesture when appropriate,
such as activating a row or clicking an editable cell, but this is currently
done too early, preventing other gestures for drag-and-drop and rubberband
selection entirely.

Do not perform coordinates transformation when gdk_event_get_position()
returns FALSE as it returns NaNs in that case and these coordinates
are not used anyway in further processing (closes#5134).
The way we explicitly set the font on the entry
conflicts with the placeholder text styling. But the
entry isn't normally empty, so placeholder text is
not that important here. Remove it and use a tooltip
instead.
When reordering notebook tabs, updating the sensitivity state of the
arrow buttons is necessary if the tab is moved to the beginning or
end of the tab list.
When notebook tabs are reorderable, pressing the notebook arrow buttons to
change the active tab results in tabs reordering unexpectedly.
Claim the event sequence after pressing an arrow button to avoid conflicts
with the motion/drag gesture used for reordering.
A typo resulted in the tab container widget being retrieved instead of
the tab widget. If an adjacent action widget was present, an infinite
loop occurred when switching tabs while a screen reader was enabled.
When we collapse a node, we clear out the children,
but we were not disconnecting the signal handler on
the child listmodel, leading to bad outcomes when
that model is persistent and changing.

As I propose to deprecate gdk_win32_surface_get_impl_hwnd() next,
replace it with the alternative.
The main difference between the two functions is that
gdk_win32_surface_get_impl_hwnd() fails gracefully by returning NULL if
the surface is not of the win32 implementation.
All the surfaces should be native surfaces here, and the existing code
doesn't seem to deal with NULL case anyway.

When some of the Emoji have been filtered out by

Currently, the wayland IM context sends zwp_text_input_v3.commit from
a number of places, and some of them with partial data. In order to
make client state updates "atomic" and complete, make the communication
happen over an unified notify_im_change() function that happens on
a narrower set of circumstances:
- The GtkIMContext is reset
- The GtkIMContext is just focused
- The gesture to invoke the OSK is triggered
- The IM context is reacting to changes coming from the compositor
Notably, setting the cursor location or the surrounding text do not try
to commit state on their own, and now will be flushed with the corresponding
IM update or reset. But also, these requests won't be prevented from
happening individually on serial mismatch, instead it will be the whole
state commit which is held off.
With these changes in place, all client-side updates are notified
atomically to the compositor under a single .commit request.

During text widget manipulation (inserting or deleting text via keyboard)
the IM context is reset somewhat early, before the actual change took place.
This makes IM lag behind in terms of surrounding text and cursor position.
Shuffle these IM reset calls so that they happen after the changes, and
ensure that the IM is actually reset, since that is currently toggled on
a pretty narrow set of circumstances.
Also, fix a bug during GtkEventControllerKey::im-update where the condition
on cursor position editability to reset the IM context was inverted.

We need to free the queued context list in dispose
if we didn't get to register the contexts, and we also
need to free the list properly when we do get to
register them.
This showed up in valgrind as leaked GList structs.
When GTK_EVENT_CONTROLLER_SCROLL_DISCRETE is set, accumulate deltas also
for mouse scroll so a high-resolution mouse wheel click behaves in the
in the same manner as a low-resolution mouse wheel click.
Instead of calculating the discrete scroll deltas in
GtkEventControllerScroll, move that code to the event constructor and
access the precalculated values using gdk_scroll_event_get_deltas.
Refactor, no functional changes.
gtk_tree_view_top_row_to_dy, which is called from GtkTreeView's
size_allocate function, changes the adjustment value. Since this
conflicts with the animation when changing the active row, bail
out until the animation is finished.

When a GtkTreeView scrolled horizontally, it was not possible to
select rows outside the initial area due to an erroneous comparison
between widget and bin window coordinates.

Commit adba0b97 fixed missed pointer crossings by using a helper function that
was already present and looked like did everything that was needed. However
this function was oriented to keyboard focus and it also did update the related
widget state. Doing these changes on pointer-based crossing was misuse, and
could cause weird interactions with keyboard focus management.
Fix this by using gtkmain.c gtk_synthesize_crossing_event() that is in fact
oriented to pointers.

Instead of passing an event and figuring out coordinates from it, pass
directly the toplevel coordinates so that we can use this outside event
handling.
All callers have been updated to pass the coordinates, in practical effects
they were already based on the GtkNative.
The inner loop in gtk_paned_set_focus_child() tries to find the
topmost GtkPaned, however, if the `w` variable ends up becoming
NULL after bubbling up the entire GtkWidget hierarchy, this loop
never breaks.
Check for NULL in this loop.

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.
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4784
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.
