Indeed (relatedly, it would be great to get this feature working smoothly with 
https://github.com/ch11ng/exwm).
Also, in a copy of emacs built with cairo, it should be possible to render each 
buffer to be displayed into a cairo surface, and scale that surface losslessly 
to generate previews.  I wonder how hard this would be to do in practice.
