- * Here's the theory:

- * maps for any keys that use the type for one or more groups. This is
- * expensive, so we'll try to cull out any keys that are obviously okay:
- * In any case:
- * - keys that have a group width <= the old width are okay (because
- * they could not possibly have been associated with the old type)
- * If the key type increased in size:
- * - keys that already have a group width >= to the new width are okay
- * + keys that have a group width >= the old width but < the new width
- * might have to be enlarged.
- * If the key type decreased in size:
- * - keys that have a group width > the old width don't have to be
- * resized (because they must have some other wider type associated
- * with some group).
- * + keys that have a group width == the old width might have to be
- * shrunk.
- * The possibilities marked with '+' require us to examine the key types
- * associated with each group for the key.
