I'd like this too.

2) gsf-output-gzip: in some contexts it would be useful to be able to
control the zlib compression level in the interest of maximum speed or
maximal compression.

I do this now with eg.:

                       obj = gsf_outfile_new_child_full(out, name, FALSE,
                               "compression-level", GSF_ZIP_DEFLATED,
                               "deflate-level", dir->deflate_level,

Perhaps the name isn't the clearest :(

Hmm, is that "child" approach applicable if you just want a wrapper for a gzipped file, as in tests/test-out-gzip1.c ? (As opposed to creating a zip archive.)
