animated svg (despite being rasterized and perhaps losing more quality).

Maybe something like this?

   Requires: emacs-28.1, compat-29.1.4.4
   Keywords: faces tools matching
   [See Screenshot]
   ^^^^^^^^^^^^^^^^

And when the user clicks it pop up a buffer with the screenshot,
similar in how Synaptic does.
