  /* Height map of a fractal mountain whose base is approximately the
    unit disc of the XY plane, with height 1 at the origin and
    dropping irregularly towards 0 along the base. 
    
    The function is actually a digital terrain with a semiregular (4,8) 
    mesh of isosceles right triangles, whose edges are smaller than {eps}.
    
    The {seed} parameter should be a number in {(0 _ 1)} used as a seed
    for pseudo-random number generators. */
