I can't find gdk source tarballs and am serious pissed

Where are gdk sources from the last tagged "stable" release?
I'm behind firewall
and therefore svn/git or any other method of the retrieval of the
"latest and greatest"
is out

And yes, I googled for about an hour or two. And I checked on
ftp.gtk.org

I'm vaguely begin to understand why kde is far more popular than
gnome:
it offers superior usability end to end.
