procedure
pict : pict-convertible?
Creates a pict that has the same drawing and bounding box of
pict, but which hides all of its sub-picts so that they
cannot be found with functions like lt-find. If pict
has a last-line pict, then the laundered pict has a fresh last-line
pict with the same shape and location.
