 > > I don't think the stuff with drop_list is spurious. The point is to
 eliminate double entries. Indices are added to drop_list if the
 corresponding point is identical to a previous one. The code you quote
 builds a new set of x, y and z where each set of point is unique.

 line, the list `x` is shortened (duplicates are removed), but then only a
 prefix of the lists `y` and `z` is dealt with (since `len(x)` decreased at
 the first line).

 Good spotting I understand what you mean now. The quick fix is to use
 len(y) and len(z) or a pre-set auxiliary variable as you have done some
 other places.
