[vtkusers] supplement: QVTK with vtk 5.0.3 and Qt 4.3.2

[Ruben Schilling]

Hi Clint,

thanks again for your feedback, it was helpful. Just to give feedback:

Dynamic linking of vtk-5.0.3 release with QVTK on x86_64 seems to work,
except the example code below, which seems to be a version mismatch in Qt
versions I guess. The CVS version of vtk produces the same results, although
I was able to use static linking there. I hope the error below will not be
linked to some deeper error in the VTK/QVTK/Qt combination, but again, I
think it looks like a version mismatch (I was using Qt 4.3.2).

Best regards and thanks
Ruben
