...turns out to be surprisingly tricky, since the nested
lib::SeveralBuilder instances require parametrisation by a
''policy template,'' which in turn relies on the actual allocator.
And we want to provide the allocator as a constructor parameter,
including the ability to pick up a custom specialisation for
some specific allocator (notably AllocationCluster requires
to hook into this kind of extension point, to be able to
employ its dedicated API for dynamic allocation adjustment)
...especially what is necessary to represent at this level and what information
is implicit; notably there will be an implicit default wiring, but we allow
for case-by-case deviations
The Builder will have to perform several passes, gradually refining
the model into the low-level Render Node network. Right now, some
guesses regarding the last steps of this process are possible,
thus defining the lowest level of a model builder structure
* Level-3 : mapping data flow paths
* Level-2 : detailed configuration of data buffer passing
* Level-1 : build the actual parameter structures for invocation
In the current »Vertical Slice« we're able to fully define Level-1
and maybe Level-2
To escape a possible deadlock in analysis, I resort to developing
some kind of free-wheeling presupposition how the **Builder** could
be implemented — a centrepiece of the Lumiera architecture envisioned
thus far — which ''unfortunately'' can only be planned and developed
in a more solid way ''after'' the current »Vertical Slice« is completed.
Thus I find myself in the uncomfortable situation of having to work towards
a core piece, which can not yet be built, since it relies heavily on
the very structures to be built...
