No, they should not be equivalent.  If you use look_at in the 3.5 camera (in
short) only their length is considered.  This behavior is similar to placing
the look_at after the up and right in the 3.1 camera model.  If you absolutely
want to change vectors look_at adjusted for you, switch the version to 3.1
when declaring the camera to get the old behavior.
