Why is image-orientation in CSS for <img>? For background-image that
makes sense, but if you are actually affecting the semantics of the
image that is displayed, it seems like it should be in HTML or a hint
in the image format.

(My reply to Boris was going to be that drawImage() should follow
whatever flag we introduce for <img> to have this behavior, seems
weird for that flag to be in CSS though.)
