Invocation: draft setup for engine context and config

Browse source 
Prototyping and analysis revealed that some aspects of the render node wiring
refers to effectively global services and can thus be taken out of the picture
by relying on classical ''Dependency Injection''

Consequently, `EngineCtx` needs a default implementation, which brings up
a simplistic fall-back version of those services in support for prototyping.
Moreover, dedicated lifecycle functionality must be provided to bring up
and shut down the actual service instances intended for operational use.

<p>
ja: ist problematisch &#8212; und genau deshalb ziehe ich jetzt vor, den Output-Buffer direkt &#252;ber den Aufruf bereitzustellen; dieser Aspekt spielt damit f&#252;r das Thema Dependency-Injection keine Rolle mehr

...es ist zwar gut, da&#223; es das LocalTag gibt, aber f&#252;r diesen Fall ist das eine unsinnige Trickserei; es ist viel besser, an der einzigen Stelle, wo das ben&#246;tigt wird (n&#228;mlich auf top-Level) explizit eine Flag zu setzen und dann den Buffer zu entnehmen

Den OutputBufferProvider handhaben wir jetzt eine Ebene h&#246;her, und dort k&#246;nnen wir direkt ein LocalTag setzen und dann ein zugeh&#246;riges BuffHandle erstellen, das nur an einen bestimmten Buffer im Output-system gebunden ist. Alle anderen Use-Cases (Memory-Bl&#246;cke und Cache) sind ohnehin global f&#252;r die gesamte RenderEngine
Den OutputBufferProvider handhaben wir jetzt eine Ebene h&#246;her; genauer, wir hanhaben ihn direkt, denn es ist nur ein einziger Buffer auf top-Level.
