  // This feature uses two strategies to eliminate stuttering:
  //
  // 1. During short segments a Graphical LCD update may take so much time that the planner buffer gets
  //    completely drained. When this happens pauses are introduced between short segments, and print moves
  //    will become jerky until a longer segment provides enough time for the buffer to be filled again.
  //    This jerkiness negatively affects print quality. The ENSURE_SMOOTH_MOVES option addresses the issue
  //    by pausing the LCD until there's enough time to safely update.
  //
  //    NOTE: This will cause the Info Screen to lag and controller buttons may become unresponsive.
  //          Enable ALWAYS_ALLOW_MENU to keep the controller responsive.
  //
  // 2. No block is allowed to take less time than MIN_BLOCK_TIME. That's the time it takes in the main
  //    loop to add a new block to the buffer, check temperatures, etc., including all blocked time due to
  //    interrupts (without LCD update). By enforcing a minimum time-per-move, the buffer is prevented from
  //    draining.
