[vtkusers] orienting programmable glyphs

[David E DeMarle]

See:
http://www.vtk.org/Wiki/VTK/Examples/Python/Visualization/ProgGlyph
for starters.

Then modify the Glyph() function to orient it. Overall what you need
to do there is get the vector for that specific point from the input's
point data, and then use that vector as the basis for the
transformation of the source geometry. I recommend you use a transform
filter to do the transforming.

See the implementation of the vtkGenericGlyph3DFilter for specifics.
