-to be ready for the release
   -3 recorder files for graf2d (Olivier)
   -1 recorder file for Fitpanel (Lorenzo)
   -1 recorder file for graf3d (Matevz)
   -1 recorder file for the GUI in general (Bertrand)
   -1 recorder file for the GUI Builder
 -gviz/graphviz installation complete and well tested
    -TGraphStruct/Node:SavePrimitive implemented

Ideally all recorder files should come with a test suite to verify
that the graphics generated by the recorder is OK (a la stressGraphics).
For example the FitPanel test suite should test that the objects generated and the
fit results are identical to the original session.
