For instance, if I dump the contents of a Mozilla Firefox window, and use the -nobdrs option, I still get all the window decoration (scroll bars, etc.).  All I want from this xwd execution is the contents of the web page.

Is this content available in the x windows display buffer? Or is the remainder of the web page (non viewable) under control of the Firefox and firefox displays the next page of content when I scroll the window?

If all you want is to create screenshots of web pages, there are better 
ways to do that than dumping the contents of a Firefox X11 window. There 
are tools based on WebKit or gecko which do just that. wkpdf or 
webkit2png are just two of the many.
