Comment 4 for bug 500125

1 mm is 40 hpgl units of course.

I made in KWrite file : IN;PU0,40;PD40,40;PD40,0;PD0,0;PD0,40;PD0,40;PU; .
It gives rectangle 1,1x1,1 mm in Inkscape.
This 0,1 mm is from "simplification threshold")and is another problem.

Now :

1. open .plt and save .plt - makes no diffrent in scale.
2. open .svg or new and save as .plt - gives hpgl unit 1/50 not 1/40 mm.

Some works, some works not ...
