/**
 * A `GtkWindow` is a toplevel window which can contain other widgets.
 * 
 * ![An example GtkWindow](window.png)
 * 
 * Windows normally have decorations that are under the control
 * of the windowing system and allow the user to manipulate the window
 * (resize it, move it, close it,...).
 * 
 * # GtkWindow as GtkBuildable
 * 
 * The `GtkWindow` implementation of the [iface@Gtk.Buildable] interface supports
 * setting a child as the titlebar by specifying “titlebar” as the “type”
 * attribute of a <child> element.
 * 
 * # CSS nodes
 * 
 * ```
 * window.background [.csd / .solid-csd / .ssd] [.maximized / .fullscreen / .tiled]
 * ├── <child>
 * ╰── <titlebar child>.titlebar [.default-decoration]
 * ```
 * 
 * `GtkWindow` has a main CSS node with name window and style class .background.
 * 
 * Style classes that are typically used with the main CSS node are .csd (when
 * client-side decorations are in use), .solid-csd (for client-side decorations
 * without invisible borders), .ssd (used by mutter when rendering server-side
 * decorations). GtkWindow also represents window states with the following
 * style classes on the main node: .maximized, .fullscreen, .tiled (when supported,
 * also .tiled-top, .tiled-left, .tiled-right, .tiled-bottom).
 * 
 * `GtkWindow` subclasses often add their own discriminating style classes,
 * such as .dialog, .popup or .tooltip.
 * 
 * Generally, some CSS properties don't make sense on the toplevel window node,
 * such as margins or padding. When client-side decorations without invisible
 * borders are in use (i.e. the .solid-csd style class is added to the
 * main window node), the CSS border of the toplevel window is used for
 * resize drags. In the .csd case, the shadow area outside of the window
 * can be used to resize it.
 * 
 * `GtkWindow` adds the .titlebar and .default-decoration style classes to the
 * widget that is added as a titlebar child.
 * 
 * # Accessibility
 * 
 * `GtkWindow` uses the %GTK_ACCESSIBLE_ROLE_WINDOW role.
 * 
 * # Actions
 * 
 * `GtkWindow` defines a set of built-in actions:
 * - `default.activate`: Activate the default widget.
 * - `window.minimize`: Minimize the window.
 * - `window.toggle-maximized`: Maximize or restore the window.
 * - `window.close`: Close the window.
