REVISION SUMMARY
  This removes any kind of scaling from the specific implementations, they
  now truly report the bare minimum size needed, as well as a corresponding
  image. AbstractBarcode scales this to the requested size, and, for now,
  adds the previous magic numbers to the minimum size.
  
  This is a further step towards allowing applications full control over
  scaling for properly handling high DPI scenarios.
  
  There's two noteworthy behavior changes in this:
  
  - minimumSize() now also works before calling toImage() for the first time.
  - toImage() returns valid results down to the actual minimum size, not only
  
  to what minimumSize() reports.
