Thanks Mark,

I used Poly2Pov to get the coefficients automatically.  I actually shot my
first "octic" after posting.  It did render, but it was extremely speckled.

Not very good.  And I explicitly called the Sturmian root solver, even
though it's automatic for higher orders.

I wonder if there is a way to get the developers to tune this up.  I would
sacrifice speed for accuracy.
