No, it's not.
Viewport is window (or part of window) where part of frame contents visible.
Frame is a special element of the document.
:D
-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...).
Actually, they call the same FrameView::paintContents and work similar, so with
accel. compositing QWebElement::render will not render layers.
That is not my point.
Conceptually, from an API point of view, you could render stuff with
software fallback when rendering sub-tree. Using software fallback for
QWebFrame::render() depending on the paint device would be too difficult
for us to ensure.
(Also note the implementations are actually differents, rendering
through QWebElement renders with a root layer and without compositing)
