        * plug-ins/common/csource.c: new save-image plugin to dump a
        straight c-source RGB or RGBA data array (most convenient
        to create libart ArtPixBuf structures from).

        * plug-ins/common/header.c (save_image): if we don't know the
        image type, complain and don't claim to have handled it.
