    The problem: XDraw draws 2 straight lines, from vlist[0]
    to vlist[1] to vlist[2].

One of the features of X10 is that the graphics were very ill-defined,
and this survives today in the compatibility functions.  I'm half-guessing,
but I think you need at least four points for a curve to work.  (If you
really on have three points, you can try cheating by replicating the
last point.)
