will be simplicial (e.g., triangles in 2-d).  Coincident points will
create small regions since the points are joggled apart.  Joggled input
is less accurate than triangulated output ('Qt').  See <a

<p>The output for 3-d Delaunay triangulations may be confusing if the
input contains cospherical data.  See the FAQ item
