RectilinearGrid of dimension <= 1 are not rendered

ParaView does not render anything when source is a 1D-rectilinear grid. So far, it looks like the only way to see the lines is to convert is to an unstructured grid (eg. use the Append Datasets filter) - test with attached grid .

Problem is that PVGeometryFilter uses vtkDataSetSurfaceFilter to generate the grid geometry. However, this filter only generates quads or triangle strips for >=2 dimensional grids.

Suggestion for a fix: use vtkRectilinearGridSurfaceFilter and vtkStructuredGridSurfaceFilter when dimension is < 2.
