I don't think so. This back-end is only usable to produce files, it
can't be used for interactive sessions (which is the key appeal of the
numpy/scipy/matplotlib work-flow over C/C++). IMO we should switch to
the TkInter back-end which is part of the standard Python Library. It
was not available in our python when I did package matplotlib.
