Shape palette based on the symbol palette in Stata used in scheme s2mono. This palette supports up to 10 values.
Note
Stata's ten plotting symbols all have a base pch equivalent, so this palette supports ten values on either branch and nothing is dropped: solid and hollow circle, diamond, square and triangle, plus the X and the plus sign.
