Job-Planning: Analysis for the next step

...which is build a »Job planning pipeline« step by step in a test setup, and then factor that out as RenderDrive, to supersede the existing CalcPlanContinuation and get rid of the Monads this way... Challenges - there is a inconsistency with channel usage - need to establish a way how to transport the output-Sink into the JobFunctor - need a way to propagate the current frame number to the next planning chunk

In diesem Fall w&#228;re es andernfalls notwendig, wieder innerhalb der OutputConnection ein de-Multiplexing zu machen. Und das will ich nicht, sowas geh&#246;rt in die Engine. Der OutputSink ist wirklich nur noch ein Buffer, der mit gewissen Timing-Constraints <i>bespielt werden mu&#223;</i>
