 *		SystemParametersInfoA (USER32.@)
 *
 *     Each system parameter has flag which shows whether the parameter
 * is loaded or not. Parameters, stored directly in SysParametersInfo are
 * loaded from registry only when they are requested and the flag is
 * "false", after the loading the flag is set to "true". On interprocess
 * notification of the parameter change the corresponding parameter flag is
 * set to "false". The parameter value will be reloaded when it is requested
 * the next time.
 *     Parameters, backed by or depend on GetSystemMetrics are processed
 * differently. These parameters are always loaded. They are reloaded right
 * away on interprocess change notification. We can't do lazy loading because
 * we don't want to complicate GetSystemMetrics.
 *     Parameters, backed by X settings are read from corresponding setting.
 * On the parameter change request the setting is changed. Interprocess change
 * notifications are ignored.
 *     When parameter value is updated the changed value is stored in permanent
 * registry branch if saving is requested. Otherwise it is stored
 * in temporary branch
 *
 * Some SPI values can also be stored as Twips values in the registry,
 * don't forget the conversion!
