I think I managed something, though I had to use 'move' to fix vertical 
spacing:

<move|<clipped|<image|Three-body_Problem_Animation_with_COM.gif|1w|1h|-0.1w|0.2h>||0.4h|0.76w|1.05h>||-0.5h> 
  (*)

(*) Test image from:

I just recalled how to use 'pdfcrop' without installing all of TeXlive 
("guix shell texlive-tiny ghostscript -- pdfcrop [some-pdf].pdf" on my 
distribution), and my 'image' is a PDF, so I'll use the simpler 
'pdfcrop' tool instead.

Greetings,
Maxime.
