I seem to have a loose end though -- when I examine the UIWebView's
scrollView property, it initially has a non-nil delegate. I don't know if I
should interpose as delegate and after taking my snapshot, call the
original delegate, or only set myself as a delegate instead of the original.
OK Thanks Marco. Thad did the trick!!!
As I was suspecting, my Mac mind was hiding the solution from me. I didn't
guess that the UIWebView had its own internal UIScrollView to support all the
navigation gestures (scroll, zoom, rotate, translate etc.)

documents, etc. Anyway, it will display a single, static, local document (not
