[Paraview] How to stop ParaView from triangulating imported cells

[Utkarsh Ayachit]

Pieter,

The file you sent has 20 tets (not quads) and hence I see the
surface-triangles. Or am I missing something here? Try opening the
spreadsheet view then switch it to show cells. Each of the cells is a
tetrahedron.
