Does this cause any inconsistency wrt other similar writers?  For example, I just looked at our exporter code and it basically does:

- create vtkTriangleFilter
- switch on file type (ply, stl, vtk)
- create vtkPLYWriter/vtkSTLWriter/vtkPolyDataWriter

I imagine others have similar code.  I admittedly didn't check, but it would be nice if I could remove this vtkTriangleFilter for all cases, and not need it for some but not others...

Cheers,
