/**
 * @class   vtkBrush
 * @brief   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.
