I would use a syntax as a mix between image_map and camera.  You'd specify a
bunch of camera options, and then image_map options.  The image_map options
would determine the mapping (which determines the x and y values that), and
the camera options would determine how the new ray that was created (by
calling create_ray with those x and y values).  Then, you'd just have to
trace the ray that create_ray created.
