Yup, and yet this (singlepart) is the default we get out of
exrmultiview and what all the openexr-images sample files use. I know
multipart is not something exclusive to multiview, but the docs seemed
to indicate multipart as the preferable approach for multiview files.

Given that multipart also provides a faster access I would rather
favour it over singlepart, but backward incompatibility may be a no
go. (thus the email to get a clear picture of that).

Thanks,
Dalai
