All curves share the same Bezier points, but they differ in the weights of
the points. The black curve is a parabola {$w = 1$}. Above of this all
curves are hyperbolas with increasing weigts, below of this are elliptic curves
with decreasing weights. The line has a weight of {$w = 0$}. After this
the weights are negative increasing. The curves are the complementare
elliptical arcs to the positive counterparts.
