This controls the number of pixels an object is moved in each footstep during animated movement. The default value of 0 chooses automated control over this value, which generally results in a minimum footstep of 4 pixels that is increased when necessary to keep up with motion on the turf grid.
Be careful about using small step sizes. Icons with high contrast pixel-level detail can look pretty ugly when displaced by short distances.
