+Subject: Xi: Do not try to swap GenericEvent.
+
+The SProcXSendExtensionEvent must not attempt to swap GenericEvent because
+it is assuming that the event has fixed size and gives the swapping function
+xEvent-sized buffer.
+
+A GenericEvent would be later rejected by ProcXSendExtensionEvent anyway.
