[Paraview] Extract cells by region and colors

[Panagiotis Foteinos]

It did solve the problem back then.

However, Paraview 3.10.1 (64bits, built from sources) does not let me
turn the option "Map Scalars" off. The different colors disappear when
using the "Extract cells by region" filter.

Any suggestions? Is that problem solved in a newest release?

Regards,
Panagiotis
