/**
* SECTION: gimpprocedureconfig
* @title: GimpProcedureConfig
* @short_description: Config object for procedure arguments
*
* #GimpProcedureConfig is the base class for #GimpProcedure specific
* config objects and the main interface to manage aspects of
* #GimpProcedure's arguments such as persistency of the last used
* arguments across GIMP sessions.
*
* A #GimpProcedureConfig is created by a #GimpProcedure using
* gimp_procedure_create_config() and its properties match the
* procedure's arguments and auxiliary arguments in number, order and
* type.
*
* It implements the #GimpConfig interface and therefore has all its
* serialization and deserialization features.
*
* Since: 3.0

* paired with a call to gimp_procedure_config_end_export() at the end
* of run().
*
* It does everything gimp_procedure_config_begin_run() does but
* provides additional features to automate file export:
*
* If @mime_type is non-%NULL, exporting metadata is handled
* automatically, by calling gimp_image_metadata_save_prepare() and
* syncing its returned #GimpMetadataSaveFlags with @config's
* properties. (The corresponding gimp_image_metadata_save_finish()
* will be called by gimp_procedure_config_end_export()).
*
* The following boolean arguments of the used #GimpSaveProcedure are
* synced. The procedure can but must not provide these arguments.
*
* "save-exif" for %GIMP_METADATA_SAVE_EXIF.
*
* "save-xmp" for %GIMP_METADATA_SAVE_XMP.
*
* "save-iptc" for %GIMP_METADATA_SAVE_IPTC.
*
* "save-thumbnail" for %GIMP_METADATA_SAVE_THUMBNAIL.
*
* "save-color-profile" for %GIMP_METADATA_SAVE_COLOR_PROFILE.
*
* "save-comment" for %GIMP_METADATA_SAVE_COMMENT.
*
* The values from the #GimpMetadataSaveFlags will only ever be used
* to set these properties to %FALSE, overriding the user's saved
* default values for the procedure, but NOT overriding the last used
* values from exporting @original_image or the last used values from
* exporting any other image using this procedure.
*
* If @mime_type is %NULL, #GimpMetadata handling is skipped. The
* procedure can still have all of the above listed boolean arguments,
* but must take care of their default values itself. The easiest way
* to do this is by simply using gimp_export_comment(),
* gimp_export_exif() etc. as default values for these arguments when
* adding them using GIMP_PROC_ARG_BOOLEAN() or
* GIMP_PROC_AUX_ARG_BOOLEAN().
*
* Additionally, some procedure arguments are handled automatically
* regardless of whether @mime_type is %NULL or not:
*
* If the procedure has a "comment" argument, it is synced with the
* image's "gimp-comment" parasite, unless @run_mode is
* %GIMP_RUN_NONINTERACTIVE and the argument is not an auxiliary
* argument. If there is no "gimp-comment" parasite, the "comment"
* argument is initialized with the default comment returned by
* gimp_get_default_comment().
*
* Returns: (transfer none): The #GimpMetadata to be used for this
* export, or %NULL if @original_image doesn't have metadata.
