/** @file node-factory.cpp
 ** Implementation of render node setup and wiring
 ** @todo draft from the early days of the Lumiera project, reworked in 2009
 **       Development activity in that area as stalled ever since. In the end,
 **       it is highly likely we'll _indeed need_ a node factory though...
 ** @todo WIP-WIP 2024 to be reworked from ground up for the »Playback Vertical Slice«
