 *
 * Description:
 *    Header for the system preferences
 *
 * History:
 *    02/31/95 rsf   Created by Roger Flores
 *    06/26/99 kwk   Added LanguageType.
 *    06/30/99 CS    Added MeasurementSystemType, then added it to both
 *                   CountryPreferencesType and SystemPreferencesType,
 *                   and bumped the version to 7.
 *             CS    Added prefMeasurementSystem to select this
 *                   preference.
 *             CS    Added filler fields to CountryPreferencesType
 *                   structure, since this guy gets saved as a
 *                   resource.
 *    09/20/99 gap   added additional cXXXX country values.
 *    09/20/99 gap   cPRC -> cRepChina.
 *    10/4/99  jmp   Add support for auto-off duration times in seconds
 *                   instead of minutes (the new seconds-based auto-off
 *                   duration time is preferred; the minutes-based auto-ff
 *                   duration times are maintained for compatibility).
 *    10/5/99  jmp   Make the seconds auto-off duration field a UInt16
 *                   instead of a UInt8; also define constants for the
 *                   "pegged" auto-off duration values (when the value
 *                   is pegged, we no longer automatically shut off).
 *    12/23/99 jmp   Fix <> vs. "" problem.
 *    04/30/00 CS    Use LmCountryType instead of CountryType.  Also removed
 *                   deprecated countryNameLength, currencyNameLength, and
 *                   currencySymbolLength, replacing usage with new
 *                   kMaxCountryNameLen, kMaxCurrencyNameLen, and
 *                   kMaxCurrencySymbolLen.
 *    05/16/00 CS    LmCountryType/LmLanguageType are now back to
 *                   CountryType/LanguageType.
 *    08/01/00 CS    Added prefLanguage & prefLocale to selector set, and
 *                   locale to SystemPreferencesType.
 *    08/01/00 kwk   Added timeZoneCountry to SystemPreferencesType, and
 *                   prefTimeZoneCountry to SystemPreferencesChoice.
 *    08/08/00 CS    Moved obsolete CountryPreferencesType to RezConvert.cp,
 *                   since that's the only code that still needs access to
 *                   this private, obsolete resource.
 *    08/08/00 peter Added attentionFlags to SystemPreferencesType, and
 *                   prefAttentionFlags to SystemPreferencesChoice.
 *    11/07/00 grant Added button default assignment resource type.
