[Paraview] Problems plotting vectors w/ Paraview 3.6.1-6.FC11.x86_64 ....

[Berk Geveci]

This is a shortcoming of the glyph filter we should address in the
future. For now, you can apply "cell centers" and then the glyph. Cell
centers creates a new dataset where points represent the center of the
cells of the original dataset.
