I tried to use vtkGlyphSouce2D and vtkActor2D.
It is almost ok, but the problem is that the arrow(refenerce vector) can't
be scaled when zooming in and out.
Laster, I tried to use vtkGlyphSource2D and vtkActor.
The arrow can be scaled properly, but it can be rotated too.
What i need is a arrow which can be scaled, but cann't rotated.
--> scaled ------>, or ->
--> rotated -->,
