[Paraview] "pseudo" random glyphs

[David E DeMarle]

Strike that, I wasn't thinking clearly.

Generate the seed points dataset as I said before.
Now use that and the TVD as inputs to the probe with Resample with
Dataset filter.
Then glyph that.

That is, randomly select the points to use, but then use the same points for each time step.  If I understand it correctly, not checking the Random Mode box causes paraview to just select the first N points.  In my case (probably most cases), this concentrates all of the glyphs in one region of the mesh.  Instead, I would like to randomly distribute the glyphs across the mesh, and using the Random Mode for this works fine for a single time step.  But if I want to animate a time series, I would like to show glyphs on the same points for each time time step, rather than have the glyphs jump all over the place.  Is there currently a way of doing this?
