(C) in RE: [Boston.pm] GD Small font

If you can't use the TTF font option (which is compiled into some Gdlib
bindings), you can plot a small circle around a small letter 'c'. I've
only put circle halos around icons, but no reason you couldn't.

On my map generated with GD.pm, I draw a small circle for highlights.

      if $highlight;
