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.
Stop trying to deal with "theoretical possibilities".
We can't possibly continue to be a faithful GActionGroup implementation
across dispose because dispose has a side effect of removing everyone's
signal handlers.
The code that we ran after the dispose chainup to do all of the fancy
signal emulation was therefore dead. The test that aimed to verify this
was buggy itself due to an uninitialised variable, so really, it never
worked at all.
We keep the re-ordering of the chainup from the original commit to avoid having
trouble with GtkActionMuxer and keep the checks in place that will prevent an
outright segfault in the case that someone else tries to use the interface
post-dispose.

GtkApplicationWindow frees its internal action group on dispose for the
usual reasons: to avoid the possibility of reference cycles caused by
actions referring back to the window again.
Unfortunately, if it happens to be inside of a GtkActionMuxer at the
time that it is disposed, it will (eventually) be removed from the muxer
after it has been disposed. Removing an action group from a muxer
involves a call to g_action_group_list_actions() which will crash
because the internal action group to which we normally delegate the call
has been freed.
A future patch that reworks the quartz menu code will introduce a use of
GtkActionMuxer in a way that causes exactly this problem.
We can guard against the problem in a number of ways.
First, we can avoid the entire situation by ensuring that we are removed
from the muxer before we destroy the action group. To this end, we
delay destruction of the action group until after the chain-up to the
dispose of GtkWindow (which is where the window is removed from the
GtkApplication).
Secondly, we can add checks to each of our GActionGroup and GActionMap
implementation functions to check that the internal action group is
still alive before we attempt to delegate to it.
We have to be careful, though: because our _list_actions() call will
suddenly be returning an empty list, people watching the group from
outside will have expected to see "action-removed" calls for the
now-missing items. Make sure we send those. but only if someone is
watching.

gtkapplication.c has turned into a bit of an #ifdef mess over time, and
many of the current checks are incorrect. As an example, if you build
Gtk for wayland, and exclude the X11 backend, much of the functionality
required by wayland (such as exporting menu models) will be disabled.
Solve that by introducing a backend mechanism to GtkApplication (named
GtkApplicationImpl) similar to the one in GApplication. Add backends
for Wayland, X11 and Quartz, with X11 and Wayland sharing a common
'DBus' superclass.

GtkApplicationImpl itself is essentially a bunch of vfuncs that serve as
hooks for various things that the platform-specific backends may be
interested in doing (startup, shutdown, managing windows, inhibit, etc.)
With this change, all platform specific code has been removed from
gtkapplication.c and gtkapplicationwindow.c (both of which are now free
of #ifdefs, except for a UNIX-specific use of GDesktopAppInfo in
gtkapplicationwindow.c).
Additionally, because of the movement of the property-setting code out
of GtkApplicationWindow, the _GTK_APPLICATION_ID properties (and
friends) will be set on non-GtkApplicationWindows, such as dialogs.

When the menubar inserted by GtkApplicationWindow is the widest
widget in a csd window, its allocation gets cut short. Fix this
by taking the decoration size into account while calculating
the size request (it is implicitly taken into account in the
size allocation phase by _gtk_window_set_allocation).
Do the menubutton for app menu fallback ourselves in GtkWindow
for the csd, non-custom titlebar case. This fits better with
the way we handle other title buttons. Themes have control
over the placement of this button by placing menu in the
decoration-button-layout style property.
Rework how accels are handled on GtkApplicationWindow.
Instead of having GtkApplication fill the GtkAccelMap which is then used
by GtkApplicationWindow to create a GtkAccelGroup filled with closures
that is then associated with the window, do it directly.
GtkApplication now keeps a list of accels and their actions.
Accelerators on a GtkApplicationWindow ask GtkApplication to execute the
appropriate action.
This saves a fair bit of complexity and memory use (due to not having to
create all those closures and accelmap entries). The new approach also
supports multiple accels per action (although there is not yet a public
API for it).
This patch (and the ones before) Reviewed and ACK'd by Matthias Clasen.
If the compositor supports the gtk-shell interface, use it to
export the application ID, dbus name and paths that can be used
for the application menu.

GtkApplicationWindow would only update its list of captured accels
when realizing the window. This meant that keyboard shortcuts added
after the window was realised (for example, added by plugins) would
be non-functional.
Solve this by updating our accels every time the accel map changes,
not only when realizing the window.

Instead of reparenting the content, use input-only windows to
set cursors and capture clicks on the window frame. This avoids
some of the problems that were introduced by content_window, such
as black flashes and non-working opacity.
Update the documentation and users of this function to handle
the future case that that we have some internal decorations to the window and
useable allocation is thus smaller.
By having a separate out parameter there is no need to have an in/out function
and allows for greater robustness.
The current implementation simply returns the allocation provided.
Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().
Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.
Remove the private header file.
Simplify the code a bit by making the initial populate part of the
bind() call.

Add an API to GtkAccelLabel for hardcoding the accel key to be displayed
(ie: allowing us to bypass the GtkAccelGroup lookup).
Use that from the GMenuModel-based GtkMenu construction code instead of
passing around the accel group.
This makes accel labels work in bloatpad again.
This patch effectively removes any hope of automatic runtime accel
changes in GMenuModel-based menus without additional application
support but it leaves the door open for this to be supported again in
the future (if we decide that it's important).

There are no remaining users of the GActionMuxer in GtkApplicationWindow
because they've all been ported over to using the one on GtkWidget (via
GtkActionHelper, for the most part).
There are no remaining users of the GtkApplicationWindow API to create
GSimpleActionObserver or to get the GActionObservable (ie: muxer) for
the appwindow. Drop those APIs.
