Utah Raster Toolkit is not needed to display images generated by RayShade.
The only thing to do is to compile RayShade with the -DNORLE option. This
will prevent RayShade to output an RLE file, and makes it output an image
file very close to MTV RayTracer's one.

The format is the following :

Xsize_of_the_image		(Numerical string)
Space				(1 byte)
Ysize_of_the_image		(Numerical string)
Newline				(1 byte)
Pixel_1_red_byte		(1 byte)
Pixel_1_green_byte		(1 byte)
Pixel_1_blue_byte		(1 byte)
Pixel_2_red_byte		(1 byte)
...

The only difference between RayShade and MTV formats, is that the first
scanline is at the bottom of the image for Rayshade, and at the top for MTV.
The output file is in a raw, not compressed, not encoded --- and thus big ---
format, but should be easily displayed on every machine.
