You're right, I did miss that, but you'd missed where I'd said I couldn't
cache the whole drawing, because it might be 60,000,000 pixels wide.
However, you did show me -viewWillDraw and it seems like a good place to
check if my visibleRect: has changed size, invalidating the much smaller
cached drawing that I have.
thanks,
