Darn, fair enough. In any case keeping it explicitly as a cache
attached to whatever is being used to view the image (eg. image
editor) would be an improvement, rather than the rest of the
application having to be aware that there's a potential 8bit version
of the same thing attached to each image.

Either way, I can't understate the usefulness of building in some
simple exposure/gamma modification attached to the image editor that
happens in the display pipeline only (on the linear data before
display transformations of course). Invaluable for checking AOVs etc.
