[ferret_users] Strange dots in dashed lines

[Ryo Furue <furue@xxxxxxxxxx>]

Hi Ferret users,

I find strange dots between dashed-line segments when I use
a "plot/dash=(down1,up1,down2,up2) . . ." command.
They seem to appear only when thickness=1.  They also appear
on the legends.  Has anybody seen this?  I'm attaching a sample
figure and the script which produces it.

I'm using Ferret 5.81 on Debian GNU/Linux (testing).

Regards,
Ryo
