you are revering to

from the `X11' manpage, right?

in what respect is line width below 1 pixel a feature for a screen device? I see that there are new devices `cairo_pdf' and `cairo_ps' but when using

X11(antialias="none")

I obviously am going to plot to the screen device. where a line width below one pixel does'nt make sense to me.

what am I missing?
