Bug with hairline arrows

Hi all,

I noticed a small bug in drawing of some hollow arrow heads if line
width is set to 0.0 (hairline). You can see this directly in dia and in
the attached eps files in arrows: left 3, right 7 and left 15.

The bug appears as add_len in arrows.c::calculate_arrow_point will be
always zero if line width is 0.0. So I set line width to 0.0001. I got
to admit that I don't know if this is the best value for it, but it

The patch is diff'ed to current cvs and attached. I would be glad if you
commit it.
