Otherwise, the old data will remain in RAM and is not reordered to the new format, so it's advisable to follow up with clear(). Usually one's sketch is implicitly using this time to generate a new frame of animation...but if it finishes very quickly, this function could be used to see if there's some idle time available for some low-priority concurrent task.
