I'm testing the panoramic projection and no matter what I put in for angle in
the camera it is 180 degrees wide. It is also 180 degrees tall. Angle has no
effect on the image at all.
Here is the entire code:

camera {
  panoramic
  location <0,0,0>
  look_at <0,0,1>
  angle 210
  //up y
  right x
}
sphere {
        <0,0,0>,10000
        pigment {
                image_map {
                        jpeg "pano.jpg"
                        //interpolate 2
                        map_type 1
                }
        }
        finish { ambient rgb <1,1,1>}
}

The pano.jpg is this:

Whatever I put in for right doesn't change the angle (horizontal or vertical)
either. You would think that it would change the vertical angle because that is
what it does for perspective. Instead it has a very strange effect of expanding
things on the left and right sides and squishing things in the middle, although
nothing new is shown and nothing is removed. Right is only correct with just the
value x, then the image matches with one side of the original image, except
mirrored, because the sphere is viewed from the inside.

This is the same for both 3.6.2 and 3.7
I'm on Vista 64 using the 64 bit versions of POV-ray.
