In the absence of icon themes (such as in a freshly
created toolbox container), we should not just fall back
to "no cursor", since that makes it hard even to close
the application. Fall back to an included default cursor
of last resort.
Provide a fallback cursor of last resort. Otherwise,
we end up with no visible cursor if there is no
cursor theme installed, wihch is less than helpful.
If the wl_surface receiving touch events is destroyed, we will get no
wl_touch.up event to remove the touchpoint from our internal accounting.
Check for this, and drop touchpoints happening in surfaces that do
disappear during operation.
The api to configure surfaces is now GdkToplevelLayout
and GdkPopupLayout. Unfortunately, there's still quite
a bit of internal use of GdkGeometry that will take some
time to clean up, so move it go gdkinternals.h for now.

We don't create a grabbing popup if it's not the top most one, as that
is a protocol violation, and complain if anything attempts to do it.
What we didn't do is handle this gracefully in the code that tries to
create said popup.
Fix this by dropping the attempt to show the popup on the floor, instead
of setting various state making it look like it succeeded. This won't
actually fix anything, but it'll result in a bit more accurate warnings
logged, as the state more correctly corresponds to the reality.
When we autohide a popup surface with a grab, hide all other auto hiding
popups up the popup chain. The end result is that when you click outside
a menu with submenus open, the whole menu chain is dismissed.
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.
The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.
The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.
For the X11 backend, keep a list of monitors for which the surface
intersects the monitor area.
Whenever the X11 surface is configured, check against the list of
monitors to determine whether it enters a new monitor or if it left a
monitor, to emit the corresponding ::enter/leave-monitor signals just
like a Wayland compositor would.
As monitors can be added, removed or reconfigured at any time, redo
those checks whenever any of these events occur.
Stop rewriting key and focus events on the GDK side.
Instead deliver them as they are, and propagate them
from the root on the gtk side, in gtkmain.c. And
stop complaining about focus events on popups - we
can just ignore them if we have no use for them.
A toplevel will only ever be transient-for to another toplevel, and only
a toplevel will ever be transient-for, so move the field into the
GdkWaylandToplevel, and make it a pointer to another GdkWaylandToplevel.
We them up there, so that code higher up compared to where they are
defined now can make use of them. Also add a few macros for type
checking and casting.
The third version of xdg-shell introduces support for explicit popup
repositioning. If available, make use of this to implement popup
repositioning.
Note that this does *NOT* include atomic parent-child state
synchronization. For that,
https://gitlab.freedesktop.org/wayland/wayland-protocols/issues/13 will
be needed.
This currently uses my own fork of wayland-protocols which adds meson
support, so that we can use it as a subproject. Eventually when
wayland-protocols' meson support lands upstream, we should change it to
point there.
Silence some meson warnings while at it to make CI happy.
This also bumps the glib requirement, since g_warning_once() is used.
We don't need all of them, only the ones that contain public API. This
allows us to reduce the chance of a stray symbol getting incorrectly
added to the introspection data.
This removes the use of the context menu and shift group
intents in gdkevents.c. If it turns out to be important,
we need to introduce vfuncs for gdk_event_triggers_context_menu
and gdk_event_matches.
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.
We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().
At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.
Update all callers.
The win32 backend is using GDK_MOD2_MASK for AltGr,
so define GDK_MOD2_MASK locally to keep this working,
but remove any mention of GDK_MOD3_MASK,...,GDK_MOD5_MASK.
