[Paraview] streamline tracer does not work on cut filter results

[Dominik Szczerba]

Thanks for a hint, but no, applying SurfaceVectors prior to StreamTracer 
does not help. I made sure the line is in plane. I manage to get a few 
very short bits of streamlines but they die out quick. So indeed sounds 
like in-plane accuracy. I checked the range of my velocity and after 
SurfaceVectors the range in the plance normal direction is NOT zero. I 
used the Calculator to put it explicitly to zero, but it did not help 
either. BTW. I can correctly display velocity as glyphs on the cut. 
Anything else I can do to make sure it is not a bug?
