My mistake. I confused myself when looking at the server side
implementation. One list is correct.

Two padding bytes, and the fact that the length of the list is implicit
(similar to xproto PolyPoint/PolyLine/etc), as far as I can see.

For bonus points, you can also modify the rest of the randr requests
that use an RROutput to use your new xidtype instead of CARD32 where
appropriate.
