[webkit-dev] get the bits of the complete page

hi, iam working on the gtk port of webkit and have a need to get the bitmap of the entire page without actually rendering it. Is there an easy way to get in the current implementation. one of the ways i thought was to create a cairo surface over a memory buffer (instead of the drawing window in webkit_page_expose_event) and pass it to the scrollview::paint with a complete rectangle. Not sure if this is the right track to solve this issue (also this could be performance/memory intensive) Any inputs would be greatly helpful. thanks, Zaheer
