Disables the internal polling of X11 events in the main loop.
Libraries or applications calling this function will be responsible of polling all X11 events.
You also must call handle_event to let Clutter process events and maintain its internal state.
This function can only be called before calling init.
Even with event handling disabled, Clutter will still select all the events required to maintain its internal state on the stage Window; compositors using Clutter and input regions to pass events through to application windows should not rely on an empty input region, and should instead clear it themselves explicitly using the XFixes extension.
This function should not be normally used by applications.
