for card corresponding to ToWindowStream.)
(* * rht 11/18/84: Major hacking. Now checks for all sorts of illegal cases. Either goes ahead with copy, converts
link type to "Unspecified", or deletes the new "invisible" link. The latter will change when imageobj fns can
return DON'T.)
(* * rht 12/12/84: now does RETFROM instead of adding processes to delete imageobj's. This is cleaner, but still
ugly.)
(* * rht 3/25/85: Fixed to handle copies within a sketch card. That is indicated by nullity of the two textstream
args.)
(* * rht 3/24/86: Changed call to NC.CoerceToID to NC.CoerceToCard)
(* * fgh 6/30/86 Now ERROR! out of attempt to copy between NoteFiles)
