I want to find a parametric representation of
the general (2 dimensional) conic curve:
  
    a*X**2 + b*X*Y + c*Y**2 + d*X + e*Y + f = 0.

Note, this is a general, rotated conic; it could
be an ellipse, parabola, or hyperbola (or line(s)).

What I want are 2 parametric functions representing
the above locus: X=G(t) & Y=H(t), so the curve
can be rendered.

Boundary points on the curve would determine start
and end values for t.
