	In a similar vein, I would like to be able to scroll my view.
The problem I am having is that the docView is bigger than the
possible visible view. I get the visible rectangle and draw in it, but
when I call display: I get logged off! I was wondering were there any
good examples of drawself routines that are integrated in a
ScrollView. Thanks for the help.
