you need to check here if you're in software mode
(!is_accelerated_compositing_active_), and if so, you need to use the number of
DoDeferredUpdate calls that ran to completion for numFramesSentToScreen.
Similarly, you need to track the number of times we call webwidget()->animate
[the top of doDeferredUpdate) in software mode, and return that for
animationFrameCount.

Now we have renderingStats() in WebView instead of WebWidget. Does this still
apply?
