One could optimize "if two consecutive line segments are straight and
point to the same direction, remove point in the middle", but this
would not remove the bug.

PS: if it's only about the round-off error - why not putting some
"lineto" statements every now and then instead of rlineto? I guess
rlineto result in smaller files, but one doesn't need to "stroke" the
line in the middle of curve.
