    So, I tried to clarify a bit that we have display aspect ratio
    selectable, updated cingg team copyright year, added even more
    finegrained sar/dar reporting (guessed, container detected, codec
    detected).

    I tried to use libavutil function for reporting SAR in
    setformat.C but it need some dynamic gui subwindow/object, not
    static BCTitle... so just prototype that does not update as you
    update window, only calculated on window objects create time, so
    each time you reopen set format window.

    3 new git diff patches hopefully for application

    0003 should be applied on top of

    0001-Add-guessed-detected-SAR-DAR-values-to-ffmpeg-asset-.patch

    from another thread


    one plain diff patch just for showing where SAR info might
    surface if I ever learn now to create dynamic text subwindows :)


oh, I calculated SAR wrongly in setformat patch, so this one should  obviously only considered as placeholder/mockup.

Still not sure to what exactly w/h ratio fields in setformat window relate - I thought about preset vs canvas size but this does not hold up in testing ...

According to the Cin-CV manual:
http://cinelerra-cv.wikidot.com/cincv-manual-en:project-attributes#toc4

    *W Ratio, H Ratio*
    Sets the ratio of the new canvas size (W, H) to the old (previous)
    canvas size (W, H). The new canvas size is recalculated based upon
    a certain factor in the W Ratio, H Ratio fields. A practical
    use-case: The current resolution is 640x480, and for some reason
    you want it to be 1.33 times wider. You don't have to calculate
    what 640x1.33 is; you type 1.33 into the "W" input instead, and
    Cinelerra calculates it for you. This tutorial
    
<https://linuxvideoediting.blogspot.com/2023/08/canvas-w-ratio-h-ratio-cinelerra.html>
    explores in more detail these settings. It is in Russian but
    easily translatable with GoogleTranslator, DeepL or similar.

The latter Tutorial can be translated ......

Excuse me for the parlance used in the refered blogpost.. I was not aware it had been mentioned before on our mailinglist...
