/**
* This is an abstract internal-use-only context implementation to be
* used as a subclass for other internal-use-only contexts that wrap
* other internal-use-only contexts.
*
* We use this context to make it easier to chain an existing context
* as part of a new context implementation. It just delegates everything
* to the inner/parent context. Subclasses then only need to override
* the methods relevant to them.
