Ichthyostega f05402c04e Library: a stricter criterion for Lumiera iterators
On occasion of the recent improvements, I noticed that somewhere
in the past I had misunderstood the meaning of the typedefs in iterators:
 * `reference` is the central definition; this is what the iterator yields
 * `value_type` is secondary; this is the type you use to store results

So at times I defined only a `value_type`, wrongly assuming this to be
the primary definition, and all the other ones to be ephemeral.

Consequently the trait to detect a »Lumiera Forward Iterator« should be sharpened...

...which unveils a long-standing bug in our ''Duck Detector''
(it is not possible to define a pointer to a reference, causing
a check for the `reference` typedef erroneously to fail.

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.
