I use the pgf package for this (included with gwTeX).  It's a 
lower-level solution than XYpic (if anything, at least
as cumbersome as picture), but with picture or XYpic I tend to get 
jagged diagonal lines (perhaps I'm doing something
wrong - I've heard you get better results from XYpic in dvips than in 
pdftex, but I would like to stay with pdftex).
