  * Base-class that an AwContents embedder derives from to receive callbacks.
  * This extends ContentViewClient, as in many cases we want to pass-thru ContentViewCore
  * callbacks right to our embedder, and this setup facilities that.
  * For any other callbacks we need to make transformations of (e.g. adapt parameters
  * or perform filtering) we can provide final overrides for methods here, and then introduce
  * new abstract methods that the our own client must implement.
  * i.e.: all methods in this class should either be final, or abstract.
