Note that even if you use TwoWayScrollPanes to implement this, each 
PasteUpMorph hangs on to a full-sized bitmap. These can be huge. But if 
that's what you need, look at what I did in my Connectors with the 
NCScrolledCompositeStateMorph.

I may do a ScrolledPageMorph sometime soon for a project of my own; this 
would be a subclass of TwoWayScrollPane that would have a PasteUpMorph. It 
would limit its size to the size of the PasteUpMorph (I think), and would 
have an API to set its underlying page size. Or I'd change BookMorph to call 
pageSize: (a new method I'd write) rather than extent:.

And it would print full-sized pages, with no scroll bars.
