      computation queues. Internally is uses a static map of hard-coded
      ascii-art letters ('a'-'z)'=('A'-'Z'), ('0'-'9') and ' '-'/' are defined yet.
      which associates letters to letter images and corresponding offsets.
      Some tests showed, that is runs very fast (about 100ns per call).
      Note, that no line-break mechanism is implemented, so the labeling
      is restricted to a single line, which is cropped, if the label would
      overlap with the right or bottom  image border.
