Function to calculate the horizontal field of view. Unreal uses the horizontal field of view for camera calculations. You can access the current field of view from the camera, however this is useful for calculating FOV values other than the current.
FieldOfView = 2 × Atan ( CameraSensorWidth / ( 2 × FocalLength ) )
