The knot controls are included in the scene file. Each keyframe has two ASCII
lines, the first containing position, heading and scale, and the second line
contains 4 numbers, the first being the keyframe number, the next three are
tension, bias and continuity. I believe the splines calculation method that LW
uses is the standard one, listed in the manual somewhere.
