[Paraview] Slowness : paraview 3.10.0 & ProgrammableFilter

[Aashish Chaudhary]

Hi Aurélien,

I did confirm that it is slow now (5 times slower with a sphere having
a million points on my linux 64 system). I will see if I can fix it
soon (first need to find the reason).

Thanks for reporting this.
