[R] ggplot2: deterministic position_jitter & geom_line with position_jitter

You'll probably need to reorder the factor, then jitter it, and then
add custom labels with scale_continuous().  I think I see how to
resolve this problem in general (two displays of the same jittered
data), but it requires basically a complete rewrite of ggplot2, so
it's unlikely to appear before ggplot3.
