The application menu isn't particular relevant anymore, and the support for
showing fallback appmenu as a headerbar icon is one of the things tying
GtkWindow to GtkHeaderBar.
Remove support for "menu" window decoration element completely, update
GtkHeaderBar docs.
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.
As Timm Baedert pointed out, the previous fix made the
menubar go on top of popovers, which is just wrong. Instead,
make gtk_window_snapshot handle all direct children of the
window, taking care to stack popovers correctly.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.

Caller(s) aren't expecting a need to delete help_overlay themselves
once they've installed it. (E.g. see gtk_application_window_added()).
I didn't notice any direct precedents, but there's a parallel in the
current implementation of gtk_container_destroy() which uses
gtk_widget_destroy() on any added widget.
This avoids leaking 100s of kB per window, when I tested nautilus.

This allows the use of a "text-direction" hint set to one of "none", "rtl",
or "ltr" to enforce the text direction of a "horizontal-buttons"
display-hint.
This is useful when a menu has buttons that map to physical space in the
UI and therefore must match the application widgetry.

Add a way to associate a detailed action name with a shortcut.
If the action name is set, update the accelerator whenever
accels change on the window that the shortcuts window is
associated with.

When the $(resource_prefix)/gtk/help-overlay.ui resource exists,
load a GtkShortcutsWindow from it for each GtkApplicationWindow,
and set up a win.show-help-overlay action with accels <Primary>F1
and <Primary>? to show it.
Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
