highlighting things in a table

I want to change how things highlight in a table (i.e., I want to do
something other than the regular boxing).
how? I tried making a clim:highlight method, which works except that
the position is wrong--it's window-relative rather than cell-relative.
Actually, output record coordinates are stored in a parent-relative
coordinate system, so just drawing the highlighting at the coordinates
given by the output record will give the wrong result.
what's the right way?
Here's an example that assumes a rectangular output record:
(define-presentation-method highlight-presentation ((type <type>) record stream state)
(declare (ignore state)) ;we'll just use XOR
(multiple-value-bind (xoff yoff)
stream (output-record-parent record))
(with-bounding-rectangle* (left top right bottom) record
(+ left xoff) (+ top yoff)
(+ right xoff) (+ bottom yoff)
:ink +flipping-ink+ :filled t))))
