save

Makes a copy of the current state of @snapshot and saves it on an internal stack.

When method@Gtk.Snapshot.restore is called, @snapshot will be restored to the saved state.

Multiple calls to method@Gtk.Snapshot.save and method@Gtk.Snapshot.restore can be nested; each call to gtk_snapshot_restore() restores the state from the matching paired gtk_snapshot_save().

It is necessary to clear all saved states with corresponding calls to gtk_snapshot_restore().
