/*
 * GIMP_CONFIG_PARAM_SERIALIZE - A property that can and should be
 *                               serialized and deserialized.
 * GIMP_CONFIG_PARAM_AGGREGATE - The object property is to be treated as
 *                               part of the parent object.
 * GIMP_CONFIG_PARAM_RESTART   - Changes to this property take effect only
 *                               after a restart.
 * GIMP_CONFIG_PARAM_CONFIRM   - Changes to this property should be
 *                               confirmed by the user before being applied.
 * GIMP_CONFIG_PARAM_DEFAULTS  - Don't serialize this property if it has the
 *                               default value.
 * GIMP_CONFIG_PARAM_IGNORE    - This property exists for obscure reasons
 *                               and is needed for backward compatibility.
 *                               Ignore the value read and don't serialize it.
