OK, fixed.

  (box . SIZE)    display a filled box cursor, but make it
                  hollow if cursor is under masked image larger than
                  SIZE pixels in either dimension.

So I guess SIZE is an integer?  Then this should be correct, and I've
added it:

         (cons :tag "Box with specified size"
               (const box) integer)

OK, fixed.

Ditto.
