note I'm blitzing the three webview-y methods here in
https://codereview.chromium.org/15851006/diff/7001/content/public/renderer/co...

I think this is fine for your next version of this patch: in RenderThreadImpl
you can just have a look at SynchronousCompositorFactory::HasInstance() and if
non-null do the logic to wire it up using direct call path. No
ContentRendererClient hooks needed :-)
