[Paraview] CleantoGrid tolerance parameter for merging points

[Patrick Brockmann]

Hi,

I like to see some points of an untsructured grid be merged ?
Some points have coordinates equal to 1E-14, others 0.

When applying the CleantoGrid filter there is no entries 
to specify a tolerance parameter. 

Am I missing something or the only way to do this today is to 
apply a Calculator filter before with some new coordinates results as:
ceil(coordsX*1000)/1000*iHat + ceil(coordsY*1000)/1000*jHat + ceil(coordsZ*1000)/1000*kHat
It works but I would have prefered this kind of setting available from
the CleantoGrid filter.

I have digged a similar question in 2007 
http://www.paraview.org/pipermail/paraview/2007-May/004914.html

Let me know if I should put a request on this missing feature 
on the paraview bug tracker or just live with it.

Regards
Patrick
