The OpenEXR libraries (libIlmImf) don't expose any way to change
header attributes without writing the whole file.
I can't recall any other image format that makes this easy, either, so
OIIO doesn't try to make a way to express it.
Beyond some level of trickery, header changes to a format with a
variable-sized header would pretty much always necessitate a complete
rewrite of the data portion in one way or another, no?
