Mario is the best person to answer this question, but for now I will
share an observation:
The draw package actually accepts two other undocumented line types:
"dashes" and "dot_dash". However, these only work with the "eps" and
"eps_color" terminals as far as I can tell. Also (on my system at
least) "dot_dash" does not render as I'd expect, but rather as a plain
dashed pattern, except with shorter dashes than "dashes".
Best,
Mark
