I'd suggest to have gimp_export_dialog_add() instead with semantics
similar to gtk_container_add().

I think it's not unreasonable to require creation of a new image for
exporting a single layer of a multi-layered image. But it becomes
unreasonable if you want to export all layers to separate images. We
should probably provide a script in the default distribution that
provides such functionality: File->Export Layers.
