surface of quadratic cells in multiblock is extracted before applying slice
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When loading a multibloc data composed of quadratic cells (VTK_QUADRATIC_TETRA in this case, but it is visible for other non-linear types), applying the slice filter produces the slice of the skin of the object, not the slice of the interior of the cells as it should. It is as if an intermediate "Extract surface" filter was added between the input filter and the slice filter.
