Not true.  For both field rendering and motion blur, LW works at time
steps that are smaller than the frame rate, so there *is* time for non-
linear interpolation to happen.

Note, though, that when Linear is turned on for a pair of keyframes one
frame apart, this tells LW to do *no* interpolation, not even linear.
It's a special case, for the precise purpose of allowing you to create
instantaneous (discontinuous) changes, even though the interface only
gives you access to frame-rate time resolution.
