May I suggest that all new events be Generic Events? One event isn't too
bad, but the legacy event space is already crowded.

    SwapComplete
	1	35			GenericEvent
	1	CARD8			extension
	2	CARD16			sequenceNumber
	4	2			length
	2	CARD16			evtype
	2				unused
	4	DRAWABLE		drawable
	4	CARD32			ust_hi
	4	CARD32			ust_lo
	4	CARD32			msc_hi
	4	CARD32			msc_lo
	4	CARD32			sbc_hi
	4	CARD32			sbc_lo

(I assume "extension" in the original is a typo. If it isn't and an
extra byte of data is needed, it easily fits in the two bytes of
"unused" after "evtype").
