PixelShaders for rasterization?

[Cyphre]

Sorry if my question is stupid but I'm newbie in PixelShaders technology.
It is possible to use PixelShaders for 'scanline rasterization' of texture content? If so are there any resources on the web about this?

I guess it is possible... People have even written raytracers as shaders. I doubt it could be any useful, though. The graphics cards are optimimized for simple triangle drawing. Trying to "bend" the hardware into doing something else is a bit cumbersome. Maby with the next generation of general purpose GPUs/APIs.
