BufferProvider: document the adapted structure in UML

Browse source 
There was an old UML diagram created at the time of the first draft.
It is integrated into the »OutputSlot« page in TiddlyWiki. This description
and the diagram are highly relevant for understanding the design in this case.

Unfortunately, Umbrello was "improved" with a lot of features since I used it
for the last time, but the **quality** of the software has been **degraded**,
it is now buggy and the layout is imprecise and gets messed up easily.

identical to the Latin part in `Noto Sans'.
- Disable display of package names, visibility scopes and signatures
- Use a 5 x 5 grid for alignment
- do not use inner classes and do not use other elements of the model as parameter types!
- the automatic layout is inconsitent, lacks precision and can kick elements around aribrtarily;
unfortunately it can not be disabled; the only solution is to proceed gradually from element to element.
- Snap-to has numeric problems; need to zoom in and manually adjust lines to avoid jagged edges in PNG export
- Undo / Redo is broken and can totally mess up the layout
Umbrello can save as SVG; some glitches can thus be cleaned-up with Inkscape afterwards.
💡 save after each step and make a Git commit; frequently close and re-open the application.

First and foremost, mapping can be seen as a //functional abstraction.// As it's used at implementation level, encapsulation of detail types in't the primary concern, so it's a candidate for generic programming: For each of those use cases outlined above, a distinct mapping type is created by instantiating the {{{OutputMapping&lt;DEF&gt;}}} template with a specifically tailored definition context ({{{DEF}}}), which takes on the role of a strategy. Individual instances of this concrete mapping type may be default created and copied freely. This instantiation process includes picking up the concrete result type and building a functor object for resolving on the fly. Thus, in the way typical for generic programming, the more involved special details are moved out of sight, while being still in scope for the purpose of inlining. But there //is// a concern better to be encapsulated and concealed at the usage site, namely accessing the rules system. Thus mapping leads itself to the frequently used implementation pattern where there is a generic frontend as header, calling into opaque functions embedded within a separate compilation unit.

<pre>Within the Lumiera player and output subsystem, actually sending data to an external output requires to allocate an ''output slot''
This is the central metaphor for the organisation of actual (system level) outputs; using this concept allows to separate and abstract the data calculation and the organisation of playback and rendering from the specifics of the actual output sink. Actual output possibilities (video in GUI window, video fullscreen, using a beamer, sound, Jack, rendering to file) can be added and removed dynamically from various components (Vault, Stage), all using the same resolution and mapping mechanisms (&amp;rarr; OutputManagement)

In order to be usable as //output sink,// an output slot needs to be //allocated,// i.e. tied to and locked for a specific client. At any time, there may be only a single client using a given output slot this way. To stress this point: output slots don't provide any kind of inherent mixing capability; any adaptation, mixing, overlaying and sharing needs to be done within the nodes network producing the output data fed to the slot. (in special cases, some external output capabilities -- e.g. the Jack audio connection system -- may still provide additional mixing capabilities, but that's beyond the scope of the Lumiera application)
[&gt;img[Outputslot implementation structures|uml/fig151685.png]]
[&gt;img[Outputslot implementation structures|uml/OutputSlot_components.svg]]
Once allocated, the output slot returns a set of concrete ''sink handles'' (one for each physical channel expecting data). The calculating process feeds its results into those handles. Size and other characteristics of the data frames are assumed to be suitable, which typically won't be verified at that level anymore (but the sink handle provides a hook for assertions). Besides that, the allocation of an output slot reveals detailed ''timing expectations''. The client is required to comply to these [[timings|Timings]] when ''emitting'' data -- he's even required to provide a //current time specification,// alongside with the data. Based on this information, the output slot has the ability to handle timing failures gracefully; the concrete output slot implementation is expected to provide some kind of de-click or de-flicker facility, which kicks in automatically when a timing failure is detected.

This //builder-style// setup allows to construct an ''~Activity-Term'' to model all the structural properties of an individual rendering invocation -- it is compriesed of a network of {{{Activity}}} records, which can be directly handled by the Scheduler.
