Basic time-bound Rendering

[Ichthyostega]

As Lumiera Product Owner,
I expect the Render Engine to perform a stable time-bound calculation process process,
to allow the application to play video and sound in realtime.

Establish a working Render Engine

Providing real-time playback in its simplest form amounts to building and integrating all essential parts of the Lumiera Render Engine: The Player provides the framework for building a set of Calculation Streams, which repeatedly define and dispatch a chunk of Render Jobs and pass them to the Scheduler, which controls time-based invocation and thereby causes Invocation of Render-Nodes.
