/** The Gtk::Application class handles many important aspects
 * of a GTK+ application in a convenient fashion, without enforcing
 * a one-size-fits-all application model.
 *
 * Currently, Gtk::Application handles GTK+ and gtkmm initialization, application
 * uniqueness, session management, provides some basic scriptability and
 * desktop shell integration by exporting actions and menus, and manages a
 * list of toplevel windows whose life-cycle is automatically tied to the
 * life-cycle of your application.
 *
 * While Gtk::Application works fine with plain Gtk::Window%s, it is recommended
 * to use it together with Gtk::ApplicationWindow.
 *
 * When GDK threads are enabled, Gtk::Application will acquire the GDK
 * lock when invoking actions that arrive from other processes.  The GDK
 * lock is not touched for local action invocations.  In order to have
 * actions invoked in a predictable context it is therefore recommended
 * that the GDK lock be held while invoking actions locally with
 * Gio::ActionGroup::activate_action().  The same applies to actions
 * associated with Gtk::ApplicationWindow and to the Gio::Application::activate() and
 * Gio::Application::open() methods.
 *
 * To set an application menu for a Gtk::Application, use
 * set_app_menu(). The Gio::MenuModel that this method
 * expects is usually constructed using Gtk::Builder.
 * To specify a menubar that will be shown by
 * Gtk::ApplicationWindow%s, use set_menubar(). Use the base
 * Gio::ActionMap interface to add actions, to respond to the user
 * selecting these menu items.
 *
 * GTK+ displays these menus as expected, depending on the platform
 * the application is running on.
 *
 * Gtk::Application optionally registers with a session manager
 * of the users session (if you set the register-session
 * property) and offers various functionality related to the session
 * life-cycle.
 *
 * An application can block various ways to end the session with
 * the inhibit() method. Typical use cases for
 * this kind of inhibiting are long-running, uninterruptible operations,
 * such as burning a CD or performing a disk backup. The session
 * manager may not honor the inhibitor, but it can be expected to
 * inform the user about the negative consequences of ending the
 * session while inhibitors are present.
