gui chart success

[Ben Pfaff]

I finally got the output code rewrite to the stage where it can
display charts in the GUI.  There is still a lot of work to do
(bug fixes galore), plus a huge amount of cleanup, before
anything becomes suitable to push to savannah, but I thought that
some of the eager folks around here might want to look anyway.

To take a look, grab the "output" branch from
git://benpfaff.org/pspp, e.g. if you are already in a Git
repository locally:

        git remote add benpfaff.org git://benpfaff.org/pspp
        git fetch benpfaff.org
        git checkout benpfaff.org/pspp
