[Paraview] Integrate variable filter

[Andy Bauer]

You may also want to look at the Cell Size filter which has the advanced
option to globally sum the values.

The Integrate Variable filter can give unexpected results with mixed
dimension elements since it will integrate all 0D, 1D, 2D and 3D cells.
