../gdk/gdktoplevellayout.c:217: Warning: Gdk: gdk_toplevel_layout_get_maximized:
unknown parameter 'maximized' in documentation comment, should be 'maximize'
100% symbol docs coverage.
833 symbols documented.
0 symbols incomplete.

What's left are just type system macros and windowing system opaque
structures.
Depending on the input driver, we will get XI_Motion based scroll
events for regular mouse wheels. These are intended to be handled
as discrete scroll, so detect smooth scroll events that move by
exactly 1.0 in either direction.

When being fullscreen, and wanting to unfullscreen but not caring about
whether to go unmaximized or maximized (as this information is lost), if
the GdkToplevelLayout represents the full intended state, we won't be
able to do the right thing.
To avoid this issue, make the GdkToplevelLayout API intend based, where
if one e.g. doesn't call gdk_toplevel_set_maximized() with anything, the
backend will not attempt to change the maximized state.
This means we can also remove the old 'initially_maximized' and
'initially_fullscreen' fields from the private GtkWindow struct, as we
only deal with intents now.
This is a more reliable calling point than ::resume-events, and a
good one to schedule things so they happen on a frame clock in no
special phase (Thus still fixing the original issue at 80d4a08e30)

Those requests are received while dealing with the ::layout frame
clock phase, this has the unintended side effect of making the
frame clock "rewind" to handle ::flush-events again during this
frame, which delays everything and practically halves the frame
rate.
We do intend to make the motion events dispatches on the next frame,
so do this in an idle at a slightly lower priority than layout/draw,
so the ::flush-events phase is actually requested for the next frame.

We don't need to go through the NSOpenGLContext for these.
We can just use the C API directly. It's also clearer what is using
CGLEnable() vs CGLSetParameter().
It was used by all surfaces to track 'is-mapped', but still part of the
GdkToplevelState, and is now replaced with a separate boolean in the
GdkSurface structure.
It also caused issues when a widget was unmapped, and due to that
unmapped a popover which hid its corresponding surface. When this
surface was hidden, it emitted a state change event, which would then go
back into GTK and queue a resize on popover widget, which would travel
back down to the widget that was originally unmapped, causing confusino
when doing future allocations.
To summarize, one should not hide widgets during allocation, and to
avoid this, make this new is-mapped boolean asynchronous when hiding a
surface, meaning the notification event for the changed mapped state
will be emitted in an idle callback. This avoids the above described
reentry issue.
We only called xdg_toplevel.(un)set_maximize() if the toplevel layout
changed, but this misses the case when the compositor had changed the
maximized state. Change it to call the xdg_toplevel request if either
the local layout changed, or if the layout differs from the current
state.
This fixes an issue where one couldn't unmaximize a window by double
clicking the titlebar that, had previously been maximized e.g. using a
keyboard binding.
Do the same for fullscreen.
This will sometimes mean a frame is skipped if a resize was requested
during the update phase of the frame dispatch. Not doing so can cause
trying to allocate a window smaller than the minimum size of the widget.
If compute_size() returns TRUE, the layout will not be propagated to
GTK. This will be used by the X11 backend to queue asynchronous resizes
that shouldn't yet allocate in GTK.
Not doing this means the next time the same surface is shown, if the
shadow size wasn't changed, it wouldn't be sent to the compositor, which
then would result in compositor deriving its own window geometry which
would include the shadow margin.
This fixes an issue where the file chooser dialog would grow each time
it opened.
The allocation of popups are part dependent of the allocation of the
root, which means the root must still be allocated when updates are
frozen, otherwise we'll try to allocate non-laid out popups.
This removes the GDK_CONFIGURE event and all related functions and data
types; it includes untested changes to the MacOSX, Win32 and Broadway
backends.
This removes the gdk_surface_set_shadow_width() function and related
vfuncs. The point here is that the shadow width and surface size can now
be communicated to GDK atomically, meaning it's possible to avoid
intermediate stages where the surface size includes the shadow, but
without the shadow width set, or the other way around.
GTK4 doesn't support arbitrary constraints when resizing a window (e.g.
steps, or aspect ratio), so we don't need to care about the result from
compute-size when doing interactive resizing.
This follows the trail of the Wayland backend in that GdkSurface changes
happen during the layout phase, and that a GDK_CONFIGURE no longer being
used to communicate the size changes of a surface; this now also uses
the layout signal on the GdkSurface.
If a surface scheduled a relayout, got frozen, and a layout phase
happened, then got unfrozen, it wouldn't see it's layout being
requested; avoid this race by remembering the pending phases until they
actually happened.
Reading the comment, it seems to be related being a window manager
decoration utility; this is not something GTK4 aims to handle, just drop
support for this.
