/* 
real[][] intersections(path p, path q, real fuzz=0);
Return all intersection times of paths p and q as a sorted array of
real arrays of length 2 (see [sort], page 67). The computations are
performed to the absolute error specified by fuzz, or, if fuzz is 0,
to machine precision.

Cf. exemple précédent pour l'utilisation de
real[] intersect(path p, path q, real fuzz=0);
