Add support to glyph filter to preserve random points over time.

From mailing list (Patrick Shinpaugh)
We added some functionality we were hoping you could add to the Paraview source for next release. It adds a "Keep Random Points" checkbox to the glyph filter such that if both "Mask Points" and "Random Mode" are checked, it will maintain the same random points across all timesteps rather than the default method of choosing a new set of random points for each timestep. It is only useful if the same points are referenced in the same order for each timestep. It should work cross platform.
You can see a comparison of current random and mask points

and random and mask points with keep random points

A patch is attached.
