Re: Drawing lines in Swarm Display

[Ginger Booth]

Hi, gang,
        Just to add a little more nuisance to the mix....  It would be
nice to have lines -with width-.  (Of course, linestyles would also be
nice....)  Java doesn't provide lines with width--to get that you have
to translate polylines to filled polygons, rather a nuisance.  (At 
least, that's the method I thought of.)  Annoying, since in general,
the problem is simply that a one-pixel wide line doesn't look good for
non-Manhattan geometries.

2 bits,
        Ginger
