is there a reason for commenting out this assertion?  should it just be deleted instead?

this ChangeLog needs to be revised to correspond to the actual name
of the methods.  you should probably just regenerate it completely
as the list of methods below is also out of date.

it's not clear why doComposite needs a canvas parameter if wjmaclean's
readback code is going to go below here.

> WebKit/chromium/src/WebViewImpl.cpp:2311
> +void WebViewImpl::doComposite(WebCanvas* canvas)
i'm pretty sure this canvas parameter can be deleted now.

Looking great overall.  Just these few minor issues remaining.
