Previously we relied on the application to send all X events through Cogl using cogl_xlib_renderer_handle_event. This breaks the abstraction that an application shouldn't need to know what winsys Cogl is using. Now that we have main loop integreation in Cogl, the Xlib-based winsys's can report that Cogl needs to block on the file descriptor of the X connection and it can manually handle the events. The event retrieval can be disabled by an application if it calls the new cogl_xlib_renderer_set_event_retrieval_enabled() function. The event retrieval will also automatically be disabled if the application sets a foreign display. Reviewed-by: Robert Bragg <robert@linux.intel.com>
