This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
This gives consistent behavior with e.g. Qt, Mozilla's suites and
LibreOffice (with non-truly native backends like "gen" and "gtk",
but unlike "gtk2" and "gtk3" ones that probably use true GTK menus).
This behavior is expected by at least some accessibility users, and
it seems good to behave like other common applications and toolkits
in this area. There should be no issue in doing so either for current
users, as it only enters the submenu instead of not doing anything.

Instead of delegating on the parent shell of a menu item/shell on a variety
of situations, Simplify event handling so:
1) Menu item selection is handled entirely on GtkMenuItem through crossing
events.
2) The deepmost menu shell handles clicks inside and outside of it.
This avoids the rather hard to follow gtk_widget_event() calls going on all
throughout the handling of crossing and button events, and makes menus work
again.
It was looping over all items, not breaking out when it found the first
selectable one, and then selecting the _last_ selectable one (if any)
found. So, it did exactly the opposite of its name. This made me quite
baffled when opening a submenu with right-arrow put me at its last item.
Originally, the loop set to_select and broke if the current item was
selectable and not tear-off, meaning that it would correctly select the
first suitable item. However, when tear-off functionality was removed
in commit 4ed9452e90, so was the break.
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
GtkMenu and GtkMenuBar, the two implementations of GtkMenuShell in GTK,
already draw it.
Furthermore, rendering a background here will overdraw any rendering
that the subclass will do, such as arrows for scrolling menus.
These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
Provide a mechanism for hiding the "Quit", "About" and "Preferences"
menu items from the normal places in a traditional menubar layout (in
the File and Edit menus) when the menu is being rendered in the Mac OS
menubar.
These items can already be found in the application menu.
With this feature, applications can now define a single menu to use in
all 'traditional' scenarios.
Use this new attribute in Bloatpad.

Currently we only take into account the window GActionGroup for
activating the accels.
However, the application could have some custom GActionGroup in the
chain of focused widgets that could want to activate some action if
some accel is activated while that widget is focused.
To allow applications to set accels on widgets that use custom
GActionGroups, simply use the muxer of the focused widget, which
already contains the actions of the parents.

We want to make sure that the submenu action is changed back to FALSE
_after_ the menu item has been activated. This prevents the menu
teardown handler from deleting the menu item before it can be activated.
Unfortunately, GtkMenuShell emits "hide" before the item activation.
This is probably done to prevent the application from doing things like
showing dialogs when the menu is still holding the grab.
In the case where we are doing an activate, set a boolean flag on each
of the open menus (following the parent stack) indicating that we'll be
emitting another signal soon (selection done). If that flag is set, we
defer the setting of the submenu action until we receive the second
signal.

GtkMenuTrackerItem::visible was removed a few commits ago.
It is not necessary to bind visible anyway, since the menu
tracker will insert and remove items as their visibility
changes.
Add the possibility of a GtkMenuTracker that performs no section
merging. Instead, it will report an item in the form of a separator for
subsections. It is then possible to get a separate tracker for the
subsection contents by using gtk_menu_tracker_new_for_item_link().
We have some API in GtkMenuTracker and GtkMenuTrackerItem that is
specifically designed to deal with submenus.
Generalise these APIs to take a 'link_name' parameter that we always
give as G_MENU_SUBMENU for now. In the future, this will allow creating
trackers for other types of links, such as sections.
gnome-terminal is still using this setting, so we'll let
applications override it for another cycle. It is no longer
backed by a system-wide setting, though, and it will still
go away eventually.
