Subject: Record the original reference.Named in imageParts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We will eventually want to eliminate most members of imageParts
in favor of using the c/image/docker/reference API directly.

For now, just record the reference.Named value, and we will
replace uses of the other members before removing them.

Should not change behavior.
