While trying to track down the zoom bug reported by David Trem, I got all tangled up in what appear to be completely obsolete and unneeded "zoom" etc. methods. These are left over from the original NavigationToolbar and the pre-transforms code. I would like to see all of this, including the entire original NavigationToolbar, deprecated and then removed. My guess is that no one is actually using any of it.
Comments? Does anyone know of other cruft that we might be able to clean out?
