  Focal blur aperture has no effect? (Message 1 to 5 of 5)

Why focal blur aperture has no effect on cameras other than the perspective
one? Some focal blur is calculated with the other cameras (details farther
away get a bit smoother) but for some reason it seems that the user-defined
aperture value is ignored.
  Not good.

I found the problem: In the function create_ray() in render.cpp the
jitter_camera_ray() function is not called in the other camera types, but
only in the perspective camera.
  Adding this before each initialize_ray_container_state() call seems to make
it work:

      if (Focal_Blur_Is_Used)
      {
        jitter_camera_ray(Ray, ray_number);
      }

  No comments to this? Good idea? Bad idea? Worth fixing? (Personally I think
it is.)

If this fixes the problem you described (I do not know much about
programming, so I can't say much more) then that bug must be fixed the way
you said. Period. It would be great if every bug could be fixed so quickly
:)
