vtkRayBounder - An abstract class for bounding rays

Description:

vtkRayBounder is an abstract class for bounding view rays during ray casting. Each concrete subclass must have a GetRayBounds method which, given a renderer, produces a floating point array that is w*h*2 (w = width of viewport, h = height of viewport). For each pixel, this array contains the near and far clipping values for the corresponding ray. A value of -1 means no clipping should be performed on that ray.

Methods:

	const char *GetClassName ()
	float GetRayBounds (vtkRenderer )

Detailed Method Descriptions:

Get the ray bounds - a floating point array with two values for every pixel in the viewport. These values indicate near and far clipping distances, or -1 for no clipping.
