I think the problem might not be the limitation
on the number of points. Rather, the limit is
on the xy values. If I remember correctly
(I am at siggraph, and can't look it up), the
points are represented by unsigned shorts. If your
plots are somewhat linearly scaled, by point number
64k, x or y will wrap around and xforms clips these
points.
