519 * SystemParametersInfoA (USER32.@)

521 * Each system parameter has flag which shows whether the parameter
522 * is loaded or not. Parameters, stored directly in SysParametersInfo are
523 * loaded from registry only when they are requested and the flag is
524 * "false", after the loading the flag is set to "true". On interprocess
525 * notification of the parameter change the corresponding parameter flag is
526 * set to "false". The parameter value will be reloaded when it is requested
527 * the next time.
528 * Parameters, backed by or depend on GetSystemMetrics are processed
529 * differently. These parameters are always loaded. They are reloaded right
530 * away on interprocess change notification. We can't do lazy loading because
531 * we don't want to complicate GetSystemMetrics.
532 * Parameters, backed by X settings are read from corresponding setting.
533 * On the parameter change request the setting is changed. Interprocess change
534 * notifications are ignored.
535 * When parameter value is updated the changed value is stored in permanent
536 * registry branch if saving is requested. Otherwise it is stored
537 * in temporary branch
538 *
539 * Some SPI values can also be stored as Twips values in the registry,
540 * don't forget the conversion!
