Detailed Description

provides a brush that fills shapes drawn by vtkContext2D.

The vtkBrush defines the fill (or pattern) 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.
