could also just be: append(data, length)

Looks better, done.

+    m_private = WebPrivatePtr<RawData>(raw.release().leakRef());

m_private = static_cast<RawData*>( ... ) seems to be more common

I'm confused, I don't see how this would work.  I can change the order so I'm
not creating a temporary variable though.

Note that .leakRef() is how we populate the m_private field below.

     m_private = data;
