Detailed Description

provides a pen that draws the outlines of shapes drawn by vtkContext2D.

The vtkPen defines the outline of shapes that are drawn by vtkContext2D. The color is stored as four unsigned chars (RGBA), where the opacity defaults to 255, but can be modified separately to the other components. Ideally we would use a lightweight color class to store and pass around colors.
