pict : pict?
find : pict-path?

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.

(pict-path? v) → boolean?
v : any/c

Returns #t if v is a pict or a non-empty list of picts.

(launder pict) → pict?
pict : pict?

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.
