[Paraview] Attach arrows onto streamlines/stream tubes more smoothly

[Liang Wang]

By using the arrow glyph filter on the lines/tubes, the arrows are often
slightly dislocated (and thus slightly misaligned) from the tubes
themselves (see the attached image).

In comparison, I am trying to get images like

https://i.stack.imgur.com/z8nkm.png

Logically, the arrows could have been an attribute of the
streamlines/stream tubes?
