Translations and a fast highlight-output-record for lines

   In light of the discussion on replaying output records and the
   difficulty in getting the translations correct, will the following
   function always translate correctly, or have I just been lucky?

This should work, but the performance won't be as good as it could be.

   (defmethod clim:highlight-output-record
	      ((record clim-internals::lines-output-record) stream state)
     (declare (ignore state))
     (when stream
       (multiple-value-bind (xoff yoff)
	     stream (output-record-parent record))
	 (with-translation (stream xoff yoff)
           (with-drawing-options (stream :ink +flipping-ink+
					 :line-style (make-line-style :thickness 2))
	     (with-slots (clim-internals::position-seq) record
	       (medium-draw-lines* stream clim-internals::position-seq)))))))
