In a thread about image saving in gdk-pixbuf there was (as much as
I remember) the final consensus, that implementing universal saving
interface is not a good thing. Every file format simply has a bit too much
and too different adjustable parameters. Universal writing interface would
probably ignore most of them, thus generating less-than-optimal quality
