This investigation started out as solving an already solved problem... I'll continue this as a design exercise non the less. __Some explanation__: To achieve the goal of invoking a Node end-to-end, the gap between the `Port` API, the `ProcNode` API and the `RenderInvocation` must be closed. This leads to questions of API design: ''what core operation should the `ProcNode` API expose?'' * is `ProcNode` just a forwarding / delegating container and becoming redundant? * or does the API rather move in the direction of an ''Exit Node''? This leads to the question how the opened `OutputSlot` can be exposed as a `BuffHandle` to allow to set off the recursive Node invocation. As it turns out, the onerous for this step lies on the actual `OutputSlot` implementation, since the API and output protocol already requires to expose a `BuffHandle`. Yet there is no "real" implementation available, just a Mock setup based on `DiagnosticBufferProvider`, which obviously can just be passed-through. Which leaves me with mixed feelings. For one it is conveninent to skip this topic for now, but on the other hand the design of `BufferProvider` does not seem well suited for such an proxying task. Thus I decided to explore this aspect in the form of a prototyping test....
