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

[Dominik Szczerba]

I already did it, as mentioned in a previous post. No, it does not work 
for me - does it work on my dataset for you?

In any case, that is a trivialized example, my real case is not 
symmetric and a cut plane is not easily aligned with the axes.

I suspect this might have to do with:

1) the funny range like 1.52e-18 - 1.22e-17 for point1/point2 in line 
source sub-window that I get hitting 'X/Y/Z Axis' button.

2) my mesh being quadratic and streamlining not working in such cases.

Thanks for any hints.
