[vtkusers] Problem in using vtkOrientationMarkerWidget

[jeando.barnichon at free.fr]

Hi Dean,
yes I see it works in your case, and your output is excatly what I was
expecting.
See the attached jpg file to see what I get.
I checked with vtk5.0.3 but compiled with VC++8.0, and I still get the uncorrect
output.
Dont' really know what more to do, as it's unlikely that the error comes from
vtk5.0.3 vs. vtkcvs
