public void register_standard_event_type (Display display, int event_base, int n_events)
Registers interest in receiving extension events with type codes between
event_base and `event_base + n_events - 1`.
The registered events must have the window field in the same place as core X events (this is not the case for e.g. XKB extension events).
If an event type is registered, events of this type will go through global and window-specific filters (see add_filter). Unregistered events will only go through global filters. GDK may register the events of some X extensions on its own.
This function should only be needed in unusual circumstances, e.g. when filtering XInput extension events on the root window.
