The text above with the "\sum" TeX macro comes from file
/usr/include/vtk/vtkCurvatures.h, which belongs to package libvtk4-dev.
Octaviz translates the documentation in the *.h into texinfo strings in
the *.cc files.  I will try to change Wrapping/vtkWrapOctave.c, which is
where this translation takes place.
