I was looking at my book which is current as of Jan 2003. I type this
from my pilot house so it is easy to grab. I notice you are right
that the online version has dropped "and shapes" but if you download
the pdf it is still in there...

While I'm scraping the egg off my face, I want to point out that
google groups has been kind of randomizing my posts. A couple of
posts that I didn't think had gone out just appeared and a couple that
I though I sent are still in the aether... It is kind of embarrassing
to apologize for getting a point wrong only to have another one of my
posts pop-up making the same wrong point. If any more of them appear
saying that the shapes are required please ignore them; I'm not
trying to be difficult or bone headed.
