Knowing where the look_at point is actually located is necessary with certain
camera types and if you want to do things like add focal blur. Also, it would be
needlessly difficult for users to have to try and calculate the proper rotation
angles for the camera based on the point they want the camera to look at. You
run into problems with precision and decimal points if you do it that way.
