I'm satisfied either way; the point was to clarify which res
(x or y) to use for square resolutions to avoid having to 
negotiate over both.   This precedence seems clearer with res
and res-y than with res-x and res-y.  Comments?

This is an unrelated issue, but I understand.  Since each feature is
independently negotiated, there is no problem specifying available
values of pix-x and not specifying pix-y.
