+% Used by a free user in the Library of Congress. Apparently this is used to
+% draw a partial page, which is then filled in by the results of a barcode
+% scanner and SQL database lookup. Its not clear to us exactly why this needs to be
+% done as a partial page, but its easiest to restore the operator, and it seems like
+% its a reasonably safe operator to restore, for the *very* few devices on which
+% it will have any effect. Currently this uses the 'sync_outptu' device method
+% to transfer the partial page, in future we may use a spec_op instead.
