Ichthyostega b7fc2df478 Invocation: NodeBuilder now handles all cases of partial-closure ...

This is a crucial feature, discovered only late, while building
an overall integration test: it is quite common for processing functionality
to require both a technical, and an artistic parametrisation. Obviously,
both are configured from quite different sources, and thus we need a way
to pre-configure ''some parameter values,'' while addressing other ones
later by an automation function. Probably there will be further similar
requirements, regarding the combination of automation and fixed
user-provided settings (but I'll leave that for later to settle).

On a technical level, wiring such independent sources of information
can be quite a challenging organisational problem — which however can be
decomposed using ''partial function closure'' (as building a value tuple
can be packaged into a builder function). Thus in the end I was able to
delegate a highly technical problem to an existing generic library function.
