The two adbantages of GTK that I am aware of are -- a bit faster than GTKAgg -- better support over X11 because you don't have to transfer the entire bitmap on every redraws since the native X11 commands can be transmitted. But these advantages may not outweigh their disadvantages (maintenance, inertia preventing us from refactoring). We could consider adding an svn dir w/ a bunch of experimental and/or noncore and/or not supported backends. If the backend lookup machinery were a bit more sophisticated (eg if 'backend : myformat' is specified, the imported will try and 'import backend_myformat' or something like that, thern users could use backends outside the normal install tree. Then we could remove backends we do not want to actively maintain, while providing a location in svn for those who want to keep using them and providing a friendly way for them to keep using them with mpl.
