say I have a camera

#declare Camera_Location = <3.9284, 1.492, -15.5296>;
#declare Camera_Look_At = <-1.0912, 1.5887, 2.4086>;

camera {
     location Camera_Location
     look_at 0*y
     translate Camera_Look_At
     right Camera_Aspect_Ratio * x
     blur_samples 20
     aperture .2
     focal_point Camera_Look_At
}

when I translate the camera on line 3 of the camera statement will it also
move the focal point? I found no mention of this in the docs, my pov-sense
is telling me this is the case however I thought I would just check to make
sure.

  Camera transformations are always performed after the camera parameters
have been parsed regardless of where you write the transformation.
  There was a reason for this, but I don't remember now what was it.
