I think I was misreading what you wanted, so I thought of it differently 
after rereading and now I believe you're asking about adding the gradient 
into the render output and not of an image_map used in a pigment by simply 
layering a texture over it.

For adding it to the render output of your scene file instead look at the 
example at scenes\incdemo\screen.pov which shows a way to put something in 
front of the camera to cover the entire scene being rendered.
