No more than it would be to make all the other pigments 
image_maps...except for camera portals, it isn't very similar at all. 
The only thing they have in common is that they produce colors, which 
*all* pigments do.

But you can't map the portals to a 0, 1 area...they cover a 3D surface 
defined by the object the portal pigment is applied to.
