w input with fewer or more points than coordinates
    QJn  - randomly joggle input in range [-n,n]
    QRn  - random rotation (n=seed, n=0 time, n=-1 time/no rotate)
    Qs   - search all points for the initial simplex
    Qz   - add point-at-infinity to Delaunay triangulation

Qhull extra options:
    QGn  - print Delaunay region if visible from point n, -n if not
    QVn  - print Delaunay regions that include point n, -n if not
    Qw   - allow option warnings
    Q12  - allow wide facets and wide duprid
