Ichthyostega 92b7b05ea2 Parameters: solve mixed signed / unsigned computation
There are some corner cases where the C++ number promotion rules can hurt us badly.
Devised a type selection logic to pick a suitable common numeric type explicitly,
using `std::common_type<T1,T2>` in most cases, yet handling explicitly the
case when the computation would wrap into unsigned; in such a mixed sign integral case,
we either use int64_t (when its precision suffices), or long double,
which can hold 64bit of mantissa without precision loss.

Lumiera -- the video NLE for Linux
==================================
Version: 0.pre.05~dev
:Date: 11/2025

*************************************************************
Lumiera is a non-linear video editing and compositing tool.
The Application will allow to edit footage using common
multimedia formats and audio/video stream codecs.

Lumiera features nondestructive editing, compositing tools,
a selection of effects plugins, processing in RGB, YUV and
RGB-float colour models and the ability to mix media with
differing sizes and framerates. Lumiera is especially well
suited for large and elaborate professional editing tasks
with lots of material, several scenes, nested sequences,
colour grading, 3D support, full fledged sound montage
and multiple edit versions prepared in parallel.

NOTE: as of 11/2025, Lumiera is in early development stage;
it is not usable yet. The above describes the Lumiera project
vision, the implementation of which will require many more years.

Lumiera pre-Alpha Versions
--------------------------

.This source tree doesn't contain a working video editing application yet.
Rather, it contains the framework and technology core of the envisioned
Application »Lumiera«. What we attempt to build here is innovative,
and we must engage in a series of integration steps to search for
suitable pathways towards our envisaged architecture.

Since 2024, the integration of the Render Engine takes centre stage,
in an effort to establish a steady state realtime processing and
display pipeline, still relying on generated video data rather
than using a library to read and playback a video file.
