vtk_rainbow works now, but:

octave:3> vtk_image_demo
ERROR: In /build/buildd/vtk-5.0.2/IO/vtkPNGReader.cxx, line 43
vtkPNGReader (0x21fe7e0): Unable to open file
/usr/share/vtkdata/Data/fullhead15.png

/usr/share/doc/octaviz/examples/vtk_image_demo.m

has this line:

reader.SetFileName("/usr/share/vtkdata/Data/fullhead15.png")

When I fix the path, or use this patch, that demo works fine like all others
now do.
