/**
* @class vtkSSAAPass
* @brief Implement Screen Space Anti Aliasing pass.
*
* Render to a larger image and then sample down
*
* This pass expects an initialized depth buffer and color buffer.
* Initialized buffers means they have been cleared with farest z-value and
* background color/gradient/transparent color.
*
* The delegate is used once.
*
* Its delegate is usually set to a vtkCameraPass or to a post-processing pass.
*
* @par Implementation:
* As the filter is separable, it first blurs the image horizontally and then
* vertically. This reduces the number of texture samples taken.
*
