Optional: You could update this to a using RepresentationMap = …; declaration
(preference for new code).

Thanks for the suggestion. I think I won't do this, just for consistency (I have
updated dozens of typedefs throughout this CL and all of them would have the
same rule, but I don't want to make that sweeping change at the same time).

+      RepresentationMap;
 
   // Creates an empty image with no representations.
   Image();
