This is an attempt to take aim at the next step,
which is to fill in the missing part for an actual node invocation...
''...still fighting to get ahead, due to complexity of involced concerns...''
This was an extended digression into architecture planning,
which became necessary in order to suitably map out the role
for the `TurnoutSystem` — which can now be defined as ''mediator''
to connect and forward control- and parameter data while specific
render invocation proceeds through the render node network.
* Lumiera source code always was copyrighted by individual contributors
* there is no entity "Lumiera.org" which holds any copyrights
* Lumiera source code is provided under the GPL Version 2+
== Explanations ==
Lumiera as a whole is distributed under Copyleft, GNU General Public License Version 2 or above.
For this to become legally effective, the ''File COPYING in the root directory is sufficient.''
The licensing header in each file is not strictly necessary, yet considered good practice;
attaching a licence notice increases the likeliness that this information is retained
in case someone extracts individual code files. However, it is not by the presence of some
text, that legally binding licensing terms become effective; rather the fact matters that a
given piece of code was provably copyrighted and published under a license. Even reformatting
the code, renaming some variables or deleting parts of the code will not alter this legal
situation, but rather creates a derivative work, which is likewise covered by the GPL!
The most relevant information in the file header is the notice regarding the
time of the first individual copyright claim. By virtue of this initial copyright,
the first author is entitled to choose the terms of licensing. All further
modifications are permitted and covered by the License. The specific wording
or format of the copyright header is not legally relevant, as long as the
intention to publish under the GPL remains clear. The extended wording was
based on a recommendation by the FSF. It can be shortened, because the full terms
of the license are provided alongside the distribution, in the file COPYING.
The immediate next step is to build some render nodes directly
in a test setting, without using any kind of ''node factory.''
Getting ahead with this task requires to identify the constituents
to be represented on the first code layer for the reworked code
(here ''first layer'' means any part that are ''not'' supplied
by generic, templated building blocks).
Notably we need to build a descriptor for the `FeedManifold` —
which in turn implies we have to decide on some fundamental aspects
of handling buffers in the render process.
To allow rework of the `ProcNode` connectivity, a lot of presumably obsoleted
draft code from 2011 has to be detached, to be able to keep it in-tree
for further reference (until the rework and refactoring is settled).
...which seems to be basically fine thus far
...beyond some renaming and rearranging
''it turns out that the final, crucial links,
necessary to tie all together, are yet to be developed''
