Start with a pixel per frame, increase the speed by 1 pixel/frame/frame
until you are half through, then decrease by 1 pixel/frame/frame. If
this is not fast enough to keep the cursor on-screen, start earlier
and/or faster. Ok, the metrics are certainly debatable: you probably
want everything over in 0.5 seconds or less, and want to have this in
two phases (possibly more): acceleration and deceleration.
But a mere discontinuous jump is confusing since it can happen when
blinking. A more continuous movement should usually also be friendly to
the video codec and rate.
