  In some cases you don't want the camera looking rigidly at its own
path ahead, but you might want to actually turn the camera a bit to one
side or another (eg. to temporarily look at some detail or whatever).

  One possibility is to create *another* spline which is used for the
look_at of the camera. It could be the same spline but with slight
variations or just a completely different spline.

  The idea is that since each spline point has a time value, you can
"orchestrate" the movement of the camera using them: "At time 0.1 the
camera should be located here and look at this point" (where this
point could be eg some object). This way you can eg. make the camera
keep looking at an object for a certain period of time even though it's
moving. This way you can make a virtual tour through your scene.
