  31  * Drawing a progress bar update is not cheap, so if we draw it on every
  32  * percentage change of 200 calculations we get one progress draw per 2
  33  * calculations which is slower than doing the calculations themselves. So as a
  34  * rough guide only do an update per MIN_NO_CODES_PER_PROGRESS_UPDATE
  35  * calculations
