/**
 * GtkOffscreenWindow is strictly intended to be used for obtaining
 * snapshots of widgets that are not part of a normal widget hierarchy.
 * Since GtkOffscreenWindow is a toplevel widget you cannot obtain
 * snapshots of a full window with it since you cannot pack a toplevel
 * widget in another toplevel.
 *
 * The idea is to take a widget and manually set the state of it,
 * add it to a GtkOffscreenWindow and then retrieve the snapshot
 * as a cairo_surface_t or GdkPixbuf.
 *
 * GtkOffscreenWindow derives from GtkWindow only as an implementation
 * detail. Applications should not use any API specific to GtkWindow
 * to operate on this object. It should be treated as a GtkBin that
 * has no parent widget.
 *
 * When contained offscreen widgets are redrawn, GtkOffscreenWindow
 * will emit a "damage-event" signal.
