[vtkusers] ProgrammableGlyphFilter example

[David Cole]

The VTK Wiki Examples dashboard reflects this... showing exactly the result
you describe:
http://open.cdash.org/testDetails.php?test=291794635&build=3556356

I would suspect it's a bug in VTK 5.10 which has since been fixed. (I don't
know this for a fact, but it seems to work as expected with VTK 6 and
later, but not with 5.10...)
