Following test scene shows a shift in the projection masks of these two
camera types when the number goes beyond a certain point.  That being the
fraction 5/12.

global_settings {
        radiosity {
                pretrace_start 0.4166666 // adding 7 to the end causes
change
                pretrace_end 1
                }
}

camera {
 omnimax // pretrace_start causes change in projection
// fisheye
location -10*z
look_at 0
}

background {rgb 1}
