/* This is an IBus workaround. The flow of events with IBus is that every time

*
* (Normally, IBus uses the GTK+ key snooper mechanism to get the key

*
* There are a number of potential problems here; probably the worst
* problem is that IBus doesn't forward the timestamp with the event
* so that every key event that gets delivered ends up with
* GDK_CURRENT_TIME. This creates some very subtle bugs; for example
* if you have IBus running and a keystroke is used to trigger
* launching an application, focus stealing prevention won't work
* right. http://code.google.com/p/ibus/issues/detail?id=1184
*
* In any case, our normal flow of key events is:

* GDK filter function => clutter_x11_handle_event => clutter actor
*
* So, if we see a key event that gets delivered via the GDK event handler
* function - then we know it must be one of these synthesized events, and

* => clutter_x11_handle_event()
* => clutter event delivery to actor
* => gtk_im_context_filter_event()
