interesting discussion -- thanks for pointing it out Tom

well -- for scatter plot it does make sense to demand jittering
"outside".  For boxplot -- nope.  x-axis (in standard vertical
boxplots) doesn't represent informative dimension anyways, besides
"groupping" and jitter imho would be only for visualization purpose.
Also any non-deterministic jitter could be made deterministic and
reproducible by seeding.  Since, once again, here randomization would be
added only for visualization purpose, it could e.g. always be produced
by the rng state seeded with 0 ;-)
