Actually only the one change is abrupt and that's because I put 3 points 
close together and added a very large width change to demonstrate that it 
was possible to do abrupt changes. This was because the image you linked to 
contained some quite abrupt changes and I didn't want you to think it 
couldn't do 'abrupt'. Looks like I overemphasized this capability  :-).

Anyhow I think Mike's is the better way to go for what you want to do.

Regards,
Chris B.
