[FFmpeg-user] Zoom out/scale down dynamically

I want to dynamically (per frame) zoom out/scale down a video below 100% size.
It seems that the zoompan filter would be ideal for this case, but
unfortunately it clamps the zoom ratio to [1,10], that is, it only zooms
in/scales up.  Why?  And what can I use instead?
