The overall goal is eventually to arrive at something akin to a ''»Dummy Media-processing Library«'' * this will offer some „Functionality“ * it will work on different ''kinds'' or ''flavours'' of data * it should provide operations that can be packaged into ''Nodes'' However — at the moment I have no clue how to get there... And thus I'll start out with some rather obvious basic data manipulation functions, and then try to give them meaningful names and descriptors. This in turn will allow to build some multi-step processing netwaorks — which actually is the near-term goal for the ''main effort'' (which is after all, to get the Render Node code into some sufficient state of completion)...
