[Paraview] Problem in creating slice from vtkMultiBlockDataSet with cell data

[Utkarsh Ayachit]

The problem is that all blocks in the mutliblock dataset are being 
sliced resulting in overlapping slices and hence the shuffling colors. 
To see that all the blocks are indeed being sliced, change the 
representation style of the "Slice" filter to "Outline"; you should see 
the outline for the blocks in the sliced output.

It is not possible to choose which block to slice for a slice filter. 
The way to slice only the volume data is exactly what you've done, use 
the extract block filter to extract the block and then slice it.
