Do not get a GdkEvent first and foremost, and only do that in the
parts where the GdkEvent is absolutely necessary (i.e. popping up
the WM menu for the window).
It does not require special knowledge about the ongoing event
sequences, and it can instead trust the event controller. Make
it use gtk_gesture_set_state() generically.
Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.
Closes#4904
Delegating the action to the compositor not only improves consistency
with server-side decorations, but also allows for actions that aren't
available client-side (like lower-in-middle-click).

Now that we have gtk_drag_check_threshold_double(), be consistent with
other draggable widgets and make sure we don't take over a drag before a
child does.
Fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/3513
This was needed to work around widgets claiming event sequences on press,
by ignoring them and starting the drag anyway unless they have certain
event controllers on them.
The most visible offender was GtkButton, but since the last commit it
doesn't claim the sequence anymore and we can remove the hack.
The press gesture does not need to set claimed state just for n-press
tracking, it will however reset all other click gestures on each press
if the event gets propagated all the way up.
Fixes tracking of multi-press in gestures in widgets that are children
of the window handle. E.g. the headerbar listview in the "File browser"
gtk4-demo demo.
While it's worth thinking about bringing the "windows can be dragged
with open popovers" behavior back, this does not kick in anymore, nor
should be the way to handle this given all the autoclose surface
semantic changes.
The expected behavior is that we trigger a keyboard-driven
interactive move or resize operation. But that doesn't work
with common compositors like mutter or weston, so lets not
expose non-working menuitems.
