AFAIK There's no mapping that matches the fisheye camera, so if you're 
stuck with that format for your to-be-projected material, things will 
get complicated.

If however you're free to pick a camera type, then the spherical camera 
is what you want, as it precisely matches the uv_mapping for spheres. 
(Alternatively, you can use non-uv_mapping, with "map_type 1".)
