Yes, I remember about that. Is it six months already? Wew!

Yes, I've a few things in mind...
One problem is the unused stuff inkscape leaves around... like unused 
gradients. Then there are ids that are used nowhere... Well, I suppose one 
just has to look at the typical inkscape file.

By the way, mimetypes/application-x-mswinurl.svgz has -- I think -- more than 
400 unused definitions laying around. 

Oh, I've looked at marble sources. I think I've found what you were referring 
to, but it's just an sh script with a few Perl substitutions, similar to 
those I did on occasion to some of my files. I tried my script also there, 
and I think an additional 500K may be shaved from there too.
