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().
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

This signal will be emitted whenever the gesture received a
button release or touch end event without a pairing button
press or touch begin. This usually happens when grabs transfer
input from one widget to another mid-press.

The rect parameter in gtk_gesture_multi_press_set_area is annotated as
nullable and the code handles the rect==NULL case, but the
g_return_if_fail kept that case from ever happening.
This prevents multipress sequences to possibly come from different mice.
Now the accumulated number of presses will be reset if the device changes
in the mean time.

The former can be called individually on each sequence, and the latter will
always call the former on all currently active sequences, so only implementing
resetting on cancel() works for both cases. Also, chain up on subclasses
implementing cancel.
This fixes clicking on nautilus' file list after popping up a menu, as broken
grabs are one of those situations where sequences get cancelled individually,
the "current button" wasn't properly reset, and further clicks with button != 3
were ignored.
This prevents some of our generic object implementation tests
from working with gesture objects. Instead, add g_return_if_fail
checks in all the gesture constructors.
This signal will always be paired with a ::pressed signal, unless
the sequence is cancelled, or the controller is reset. the n_press
argument in the signal always matches the ::press signal one, even
if GtkGestureMultiPress::stopped was emitted in between.
The current sequence (as per gtk_gesture_single_get_current_sequence)
is used to find out the coordinates. And only emit ::pressed if the
gesture began through a GDK_BUTTON_PRESS/TOUCH_BEGIN (eg. not due to
an extra touch being lifted)
This gesture handles any number of clicks, ensuring multiple presses
stay within thresholds and timeouts. When anything of that happens,
the gesture is reset and press count starts from 1 again.
Optionally, the gesture can be given a rectangle, used in in presses > 1
to ensure the consecutive presses happen on user imposed areas.
