I have not tried it, but assuming that the original image from SqueakJS is
a 32-bit Spur, image, then I would expect that converting to 64-bit Spur
is the same as for any other 32-bit Spur image. This requires a VMMaker based
conversion script that Eliot has developed.

If you tried that and it did not work, then I would suggest re-saving the
32-bit Spur image using an oscog VM, and then running the conversion process.

These procedures should work fine for occasional conversions, such as (for
example) producing 32-bit and 64-bit image artifacts in a CI build process.
If you need something fast and on-the-fly for internet applications, maybe
not so good.
