It seems reasonable to me to have an attribute that says that the
EXIF orientation should be honored be part of the content.  I don't
know if the rest of what's in image-orientation is needed (either in
markup or in CSS); I'd be happy to drop it from Gecko with such a
replacement, assuming that it's not going to lead to a huge amount
of churn (since image-orientation is already something we're
shipping and depend on internally, and I'd rather not have to redo
it multiple times).
