functional-postscript

Write pscat PostScript in a data-in, marks-out style with lib/functional.ps (fp-map, fp-filter, fp-fold, fp-each, fp-compose, fp-curry, fp-dip) and wrap procedures with lib/aspect.ps (aop-before, aop-after, aop-around, aop-count, aop-trace). Use when a piece is built from a list of records, or when you want to count or trace calls to a drawing procedure. Plain rendering uses the pscat skill; art libraries use psart.
