Jehan 5f4464445f libgimp*: keep 10 reserved spots for future virtual functions in every derivable class.
Hopefully this should be enough to add new features in the future
without breaking ABI, at least until GIMP 4!

* GimpRunLoadFunc:
* @procedure: the [class@Gimp.Procedure] that runs.
* @run_mode: the [enum@RunMode].
* @file: the [iface@Gio.File] to load from.
* @metadata: the [class@Gimp.Metadata] which will be added to the new image.
* @flags: (inout): flags to filter which metadata will be added..
* @config: the @procedure's remaining arguments.
* @run_data: (closure): the run_data given in gimp_load_procedure_new().
*
* The load function is run during the lifetime of the GIMP session, each time a
* plug-in load procedure is called.
*
* You are expected to read @file and create a [class@Gimp.Image] out of its
* data. This image will be the first return value.
* @metadata will be filled from metadata from @file if our infrastructure
* supports this format. You may tweak this object, for instance adding metadata
* specific to the format. You can also edit @flags if you need to filter out
* some specific common fields. For instance, it is customary to remove a
* colorspace field with [flags@MetadataLoadFlags] when a profile was added.
*
* Returns: (transfer full): the @procedure's return values.
*
* Since: 3.0
