I have submitted a patch that fixes creation of on-disk _enhanced_ metafiles
a few days ago:
It byteswaps EMF records just for writing to disk. Adding
byteswapping for reading from disk seems very easy - just feed the file
content to the same byteswapper functions. I think it is a bit more clean
than your approach.
