What is the best way to convert a parabola or hyperbola into Bezier
curveto's ?  Scaling/rotating circles seems to work well for
ellipses but suppose you want clip a section of a parabola, is it better to
determine to divide the (visible) arc into 1000 pieces and plot
using polar coordinates or to determine to equivalent Beizer curve and
use a clipped path?  So I guess the question is whether a Beizer
curve is drawn first and then clipped or whether the curve is drawn
for the window...
