Mikhail already clarified my point about variable-length arrays.
Thanks, Mikhail.

By "open-code ChangeProperty", I mean copy-and-paste the body of the
generated xcb_change_property function from libxcb, modify it to suit,
and you end up calling xcb_send_request at the end (instead of
xcb_change_property).

Ugly, but it avoids the extra copies. I can see arguments on both
sides of this one. I was just wondering what you thought of the idea.
