<remarks>This is a wrapper for marshalling between managed String.Format-style methods and unmanaged printf-style ones. The managed function should take a <see cref="T:System.String" /> format, and a <see langword="params" /> array of <see cref="T:System.Object" />, and pass that to <see cref="M:GLib.Marshaller.StringFormat" />. <see cref="M:GLib.Marshaller.StringFormat" /> will format the data, and then make sure that any percent signs in the result are doubled so that they can safely be passed to an unmanaged method that expects a printf-style string (and following arguments).</remarks>
