Ugh. Two simple solutions come to mind: (i) revert my change, or (ii)
clear the image cache on each call to image-toggle-display. I don't
know which is worse, performance-wise -- any suggestions?
We could change the cache code for file image specs so that the file
modtime in included in the image hash. But this can probably wait for
after the release -- for now, we can always call `clear-image-cache'
wherever changes to image files can be a problem. (Aside from
image-mode, I don't know where else the image cache would be a
problem.)
