Causing a grab in the handler for ::pressed by, e.g., popping up a
context menu will cause the gesture to be canceled and, subsequently,
::end and ::released to be fired, all while the button is still
physically pressed. That results in no event being available to the
::released handler and garbage coordinates, given that
gtk_gesture_get_point() returns FALSE.
Emitting ::released can be avoided by checking the return value
gtk_gesture_get_point().
Querying the event sequence of a gesture will always yield NULL for
non-touch events, but passing NULL in to calls to
gtk_gesture_get_last_event() is a perfectly valid use case.
Application is not expecting that.
Bug found due gdk_seat_grab() failure on Lock Screen. When user
Unlock the screen, the application is visible but does not receive
enter-event any more on X11/GNOME.

That code branch is meant to check for key events, seems obvious we want
GDK_KEY_PRESS, not GDK_BUTTON_PRESS (which also broke the branch right
below).
Makes us all able to dismiss popovers again.
We can just as well use notify::has-focus for the purpose of
focus tracking, and we can at the same time avoid emitting the
deprecated AtkObject::focus-event signal.
A recent dependency change in MSYS2 made it pull in vulkan, which made
meson think it's available but it somehow links against the system vulkan dll
instead.
Disable vulkan for now.
:climb-rate is not about what you get when you single-click on a button,
as this implied: it's what happens if you hold down a button or a key.
Fix the description of @climb_rate to new(), and while here, mention the
key in the blurb of :climb-rate itself.
The last round of patches to get the desired direction of value move in
response to scrolls/keypresses on scales had the inadvertent side effect
of giving the opposite direction on scrollbars. Seeing as gtkrange.c is
already a collection of hacks, add another so that fix only holds if the
instance is a GtkScale, since that is what those patches were aimed at.

We were mutating the list while iterating over it. This was not a
problem before since remove_controller just set the controller pointer
to NULL instead of actually removing it from the list of controllers.
We can avoid a signal connection per event controller (and the
EventControllerData struct) since every event controller knows the
widget it's attached to.
