Hi Petr,

I don't know what's the proper answer to this, but from "help linestyle" 
I can read:
"The line width and point size are multipliers for the default width and 
size"
And the smallest achievable linewidth for cairo-based terminals is 
definetely zero. It is a consequence of antialiasing. For example, try:

plot x-2 lw 3 lt 1, x-1 lw 2 lt 1, x lw 1 lt 1, x+1 lw .8 lt 1, x+2 lw 
.5 lt 1, x+3 lw .3 lt 1, x+4 lw .1 lt 1, x+5 lw .03 lt 1

You will probably see that even at lw 0.03 the line is visible and looks 
indeed very thin.
Do you think we should decided of a lower bound on the linewidth for 
cairo-based terminals ?

Best regards,

Timothée
