I think the way to start is to collect bounding boxes in
RenderBlock::layoutBlock() and pass them up to the TimelineAgent which will
union the rectangles into a big dirty rectangle.  One difficulty is that the
x()/y() of a RenderBlock is relative to its container where the user really
wants to see coordinates relative to the document (and for an <iframe> maybe
relative to the top-level document).  I think this means doing a lot of
mapLocalToContainer() calls - is that right?
