  33  ** This file defines a standard character set by elementary
  34  ** "draw" & "move" commands. The format is a very compact one from
  35  ** the old days where every byte was still appreciated.
  36  **
  37  ** A font or character set is an array of strings. Each character
  38  ** corresponds to one of these strings, which is addressed by its ASCII code.
  39  **
  40  ** A character is a (NULL-terminated) string of bytes. Each byte
  41  ** codes for a draw or move action according to the code below:
  42  **
  43  **     Bit:    7 6 5 4 3 2 1 0
  44  **             p x x x y y y y
  45  **
  46  **     p:      Plot flag. If set, "draw to" new point, else "move to" it.
  47  **     xxx:    3-bit unsigned integer  (0...7). X coordinate of new point.
  48  **     yyyy:   4-bit unsigned integer (0..15). Y coordinate of new point.
  49  **
  50  ** The baseline is y = 4 instead of y = 0, so characters with parts
  51  ** below it can be drawn properly without a need for sign bits.
  52  ** Function "code_to_ucoord()" transforms these coordinates into
  53  ** actual user coordinates.
  54  **
  55  ** Example:    code for character 'L': "\032\224\324" translates to:
  56  **             moveto(1,10); drawto(1,4); drawto(5,4);
  57  **
  58  ** From the example you can conclude that the font below essentially is
  59  ** defined on a 5x7 grid:
  60  **
  61  **             0 1 2 3 4 5 6 7
  62  **     15      . . . . . . . .         . : unused
  63  **     14      . . . . . . . .         * : always used
  64  **     13      . . . . . . . .         o : sometimes used
  65  **     12      . . . . . . . .
  66  **     11      . . . . . . . .
  67  **     10      o * * * * * . .
