Doing image decoding in the bios seems particularly pointless. Why don't you
just pass the bios raw image data?
If you really want to directly support fancier formats IMO it makes much more
sense to do that in qemu itself. There we can use the same libraries as
everyone else (libjpeg, libpng, etc) rather than badly reimpleenting them
inside the bios.
