The Clutter X11 backend now passes all events through _cogl_xlib_handle_event. This function can now internally be hooked with _cogl_xlib_add_filter. These are added to a list of callbacks which are all called in turn by _cogl_xlib_handle_event. This is intended to be used internally in Cogl by any parts that need to see Xlib events. Cogl now also has an internally exposed function to set a pointer to the Xlib display. This is stored in a global variable. The Clutter X11 backend sets this. _cogl_xlib_handle_event and _cogl_xlib_set_display can be removed once Cogl gains a proper window system abstraction.
