This is taking it a bit far.  There are many different use cases for
screenshots and coding the thumbnail use case specifically into QEMU
doesn't seem like the way to go.

I think ppm for lossless and png for small file size are good options to
have.  Beyond that it's up to the caller to deal with the screenshot,
which might be scaling, detecting diffs, encoding in a fancier format,
etc.
