s/WebWidgets and RenderWidgets/WebWidgetTestProxy between WebWidgets and
RenderWidgets/
?

I think this would be accurate even today, with the existing inheritance
relationship between RenderWidget and RenderView, right?

Done.
Well, I guess it depends what do you mean by correct. The RenderViews will get
WebViewTestProxies, but not WebWidgetTestProxies directly. That's why I had to
make WebViewTestProxyBase inheriting from WebWidgetTestProxyBase.
