The problem lies with the pixel painting method used by the interpreter.
One way to handle this is to use  this fragment (from the original red book
p 187)

transform round exch round exch itransform

This locks the line to the nearest pixel by converting from userspace
to machine space, rounding and then converting back to user space.
Level II has addressed this problem.

Cheers
Woody
