/**
 * Together with #GtkSocket, #GtkPlug provides the ability to embed
 * widgets from one process into another process in a fashion that is
 * transparent to the user. One process creates a #GtkSocket widget
 * and passes the ID of that widget’s window to the other process,
 * which then creates a #GtkPlug with that window ID. Any widgets
 * contained in the #GtkPlug then will appear inside the first
 * application’s window.
 * 
 * The communication between a #GtkSocket and a #GtkPlug follows the
 * [XEmbed Protocol](http://www.freedesktop.org/Standards/xembed-spec).
 * This protocol has also been implemented in other toolkits, e.g. Qt,
 * allowing the same level of integration when embedding a Qt widget
 * in GTK+ or vice versa.
 * 
 * The #GtkPlug and #GtkSocket widgets are only available when GTK+
 * is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined.
 * They can only be used on a #GdkX11Display. To use #GtkPlug and
 * #GtkSocket, you need to include the `gtk/gtkx.h` header.
