In short, my opinion on the problem is:
-conceptually, the frame is the viewport on the document -> natural 
clipping to that viewport.
-scrollbar and fixed element are adjusted to the frame, rendering 
outside the natural clipping will make them useless/out of place.
-now that I think of it, QWebFrame::render() without clipping cannot be 
made to work with accelerated compositing, while QWebElement::render() 
could (altough I don't know if it does currently...).

That is why I think such use cases - rendering the full content - should 
be addressed by QWebElement::render() && frame with resize to content.

Any opinion?
