/**
* The details of one preference which is constrained to be
* one of a small number of string values-- in other words,
* an enumeration.
*
* We could have done this other ways. One particularly attractive
* possibility would have been to represent the entire symbol table
* as a space-separated string literal in the list of symtabs, so
* the focus mode enums could have been represented simply by
* "click sloppy mouse". However, the simplicity gained would have
* been outweighed by the bugs caused when the ordering of the enum
* strings got out of sync with the actual enum statement. Also,
* there is existing library code to use this kind of symbol tables.
*
* Other things we might consider doing to clean this up in the
* future include:
*
* - most of the keys begin with the same prefix, and perhaps we
* could assume it if they don't start with a slash
*
* - there are several cases where a single identifier could be used
* to generate an entire entry, and perhaps this could be done
* with a macro. (This would reduce clarity, however, and is
* probably a bad thing.)
*
* - these types all begin with a gchar* (and contain a MetaPreference)
* and we can factor out the repeated code in the handlers by taking
* advantage of this using some kind of union arrangement.
