 // TODO(erg): Rewrite the old gtk_key_bindings_handler_unittest.cc and get them
 // in a state that links. This code was adapted from the content layer GTK
 // code, which had some simple unit tests. However, the changes in the public
 // interface basically meant the tests need to be rewritten; this imposes weird
 // linking requirements regarding GTK+ as we don't have a libgtk2ui_unittests
 // yet. http://crbug.com/358297.
