 Note: The new renderers and dmabuf support are using graphics drivers
 in different ways than the old gl renderer, and trigger new driver bugs,
 (see for example https://gitlab.gnome.org/GNOME/gtk/-/issues/6418 and
 https://gitlab.gnome.org/GNOME/gtk/-/issues/6388). Therefore, it is
-recommended to use the latest mesa release (24.0) with the new renderers.

+ *
+ * Many widgets have properties for child widgets, such as
+ * [property@Gtk.Expander:child]. In this case, the preferred way to
+ * specify the child widget in a ui file is to simply set the property:
+ *
+ * ```xml

+ *     <object class="GtkLabel">

+ *
+ * Generic containers that can contain an arbitrary number of children,
+ * such as [class@Gtk.Box] instead use the `<child>` element. A `<child>`
+ * element contains an `<object>` element which describes the child object.
+ * Most often, child objects are widgets inside a container, but they can
+ * also be, e.g., actions in an action group, or columns in a tree model.
+ *
+ * Any object type that implements the [iface@Gtk.Buildable] interface can
+ * specify how children may be added to it. Since many objects and widgets that
+ * are included with GTK already implement the `GtkBuildable` interface,
+ * typically child objects can be added using the `<child>` element without
+ * having to be concerned about the underlying implementation.
+ *
+ * See the [`GtkWidget` documentation](class.Widget.html#gtkwidget-as-gtkbuildable)
+ * for many examples of using `GtkBuilder` with widgets, including setting
+ * child objects using the `<child>` element.
+ *
+ * A noteworthy special case to the general rule that only objects implementing
+ * `GtkBuildable` may specify how to handle the `<child>` element is that
+ * `GtkBuilder` provides special support for adding objects to a
+ * [class@Gio.ListStore] by using the `<child>` element. For instance:
+ *
+ * ```xml
+ * <object class="GListStore">
+ *   <property name="item-type">MyObject</property>
