-// GtkInputEventBox is like GtkEventBox, but with the following differences:
-//  1. Only supports input (like gtk_event_box_set_visible_window(foo, FALSE).
-//  2. Provides a method to get the GdkWindow (gtk_input_event_box_get_window).
-//  (The GdkWindow created by GtkEventBox cannot be retrieved unless you use it
-//  in visible mode.)
-// TODO(mattm): Get rid of this class someday if Gtk adds a way to get the
-// GtkEventBox event_window (https://bugzilla.gnome.org/show_bug.cgi?id=657380).
