VKBD sends the events as X messages to the Gtk editing widget
(i.e. something having Gtk IM context) that has the focus.

Apparently it still synthetizes couple of keys (apparently Enter
and maybe Backspace) as normal X key events, but that doesn't work
for all keys (X key events cannot represent all unicode characters).
