[vtkusers] set caption leader color?

[Maxwell, Thomas P. (GSFC-606.2)[SCIENCE SYSTEMS AND APPLICATIONS INC]]

The vtkCaptionActor2D consists of a vtkTextActor with a border and an adjustable arrow attached to the border which is supposed to point at the feature that the caption refers to.   This arrow consists of a single line, referred to as the "leader" in the vtk source code, with a glyph used as the leader "head".   vtkCaptionActor2D extends vtkActor2D.   The (internal) leader actor is also a vtkActor2D.

Just to avoid further confusion, could you clarify what is a leader
you are talking about.
If it is part of vtkAxesActor , my advice below is correct.
