* #GimpExportProcedure is a #GimpProcedure subclass that makes it easier
* to write file export procedures.
*
* It automatically adds the standard
*
* (#GimpRunMode, #GimpImage, #GimpDrawable, #GFile)
*
* arguments of an export procedure. It is possible to add additional
* arguments.
*
* When invoked via gimp_procedure_run(), it unpacks these standard
* arguments and calls @run_func which is a #GimpRunExportFunc. The
* #GimpProcedureConfig of #GimpRunExportFunc only contains additionally added
* arguments.
*
* If @export_metadata is TRUE, then the class will also handle the metadata
* export if the format is supported by our backend. This requires you to also
* set appropriate MimeType with gimp_file_procedure_set_mime_types().
