This approach is much simpler than my initial guess. The loading of
thumbnail works, however, the table is not getting updated with the
thumbnails until I scroll. Unfortunately, because binding eliminated
almost all the glue code, it also makes it very hard to debug why it's
not getting updated. I thought that once the didChange: is called, the
NSArrayController will trigger an update on the NSImageCell and should
redraw itself.
Hmm.. I wrote the code off the top of my head, and haven't tested it
in an app. You might try sending -willChangeValueForKey: before
-didChange:valuesAtIndexes:forKey:.
