For each line, you will need a DataReferenceImpl, and then create a
ConstantMap[] for Display.RGB and Display.LineWidth, and then use:

    Display.addReference(DataReferenceImpl, ConstantMap[]);

when you add each line to the display.  In Jython, you might say
something like:

   cm = makeColorMap('red') + makeLineStyleMap('solid',3))
   addData('lines', thisline, display, cm)

(for points in 'thisline', and Display 'display', and a solid red line
of width 3)
