------- Additional Comments from David Levin <levin at chromium.org>
Verified that it is equivalent (with the added bonus of error checking).

I wish there was a way to give compile errors for instances of
"static_cast<RenderWidget*>()" to prevent it from being added again
(automatically), but I couldn't think of any way to do this.
