Locates a pict designated by find is within pict. If
find is a pict, then the pict must have been created
as some combination involving find.
If find is a list, then the first element of find must be within pict, the second element of find must be within the second element, and so on.
procedure
(pict-path? v) → boolean?
v : any/c
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.
