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

* Sends it to the daemon via D-Bus asynchronously
* When it gets an reply, synthesizes a new GdkEvent and puts it into the
* GDK event queue with gdk_event_put(), including
* IBUS_FORWARD_MASK = 1 << 25 in the state to prevent a loop.
*
* (Normally, IBus uses the GTK+ key snooper mechanism to get the key
* events early, but since our key events aren't visible to GTK+ key snoopers,
* IBus will instead get the events via the standard
* GtkIMContext.filter_keypress() mechanism.)
*
* 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
* we should push it back to clutter.
*
* To summarize, the full key event flow with IBus is:
*
* GDK filter function
* => Mutter
* => gnome_cinnamon_plugin_xevent_filter()
* => clutter_x11_handle_event()
* => clutter event delivery to actor
* => gtk_im_context_filter_event()
* => sent to IBus daemon
* => response received from IBus daemon
* => gdk_event_put()
* => GDK event handler
* => <this function>
* => clutter_event_put()
* => clutter event delivery to actor
*
* Anything else we see here we just pass on to the normal GDK event handler
* gtk_main_do_event().
