...and this line of analysis brings us deep into the ''Buffer Provider''
concept developed in 2012 — which appears to be very well to the point
and stands the test of time.
Adding some ''variadic arguments'' at the right place surprisingly leads
to an ''extension point'' — which in turn directly taps into the
still quite uncharted territory interfacing to a **Domain Ontology**;
the latter is assumed to define how to deal with entities and relationships
defined by some media handling library like e.g. FFmpeg.
So what we're set to do here is actually ''ontology mapping....''
The immediate next step is to build some render nodes directly
in a test setting, without using any kind of ''node factory.''
Getting ahead with this task requires to identify the constituents
to be represented on the first code layer for the reworked code
(here ''first layer'' means any part that are ''not'' supplied
by generic, templated building blocks).
Notably we need to build a descriptor for the `FeedManifold` —
which in turn implies we have to decide on some fundamental aspects
of handling buffers in the render process.
To allow rework of the `ProcNode` connectivity, a lot of presumably obsoleted
draft code from 2011 has to be detached, to be able to keep it in-tree
for further reference (until the rework and refactoring is settled).
As outlined in #1367, the integration effort requires some rework
of existing code, which will be driven ahead by the `NodeLinkage_test`
* redefine Node Connectivity
* build simple `ProcNode` directly in scope
* create an `TurnoutSystem` instance
* perform a ''dummy Node-Invocation''
