Thanks to everybody who replied to my previous question on 
ScrollViews (why I was losing subviews during scrolling).

Another question: Scrolling seems to be incredibly slow. 
How does one speed it up ? Are there standard ways to 
scroll quickly (and still have dynamic drawing) ?

The best idea I have (at the moment) is to implement
a compositing operation (keep a copy of the entire DocView
and copy it in). This seems somewhat baroque (and wasteful
of memory) though. 

What am I missing ?
