Hi folks,

Is there a way to get a DomRange (for instance) of the visible portion
of a web page?

I'd like to write a function that highlights a string match on a webpage, but only
in the currently visible area.

nsiSelectionController has checkVisibility so I as a last resort I
could walk each node in the document to get a range. But..I'm hoping
there's an existing way.

Thanks!

Shawn
