Calculates the distance offset to compensate for the Focal Length adjustment in a Dolly Zoom camera move. A Dolly Zoom move requires there to be a preset framing (the screen width) then when adjusting the Field of View, the Distance needs to be updated.

Distance = ScreenWidth / ( 2 × Tan( FOV / 2 ) )
