+/**
+ ** This file defines a standard character set by elementary
+ ** "draw" & "move" commands. The format is a very compact one from
+ ** the old days where every byte was still appreciated.
+ **
+ ** A font or character set is an array of strings. Each character
+ ** corresponds to one of these strings, which is addressed by its ASCII code.
+ **
+ ** A character is a (NULL-terminated) string of bytes. Each byte
+ ** codes for a draw or move action according to the code below:
+ **
+ ** Bit: 7 6 5 4 3 2 1 0
+ ** p x x x y y y y
+ **
+ ** p: Plot flag. If set, "draw to" new point, else "move to" it.
+ ** xxx: 3-bit unsigned integer (0...7). X coordinate of new point.
+ ** yyyy: 4-bit unsigned integer (0..15). Y coordinate of new point.
+ **
+ ** The baseline is y = 4 instead of y = 0, so characters with parts
+ ** below it can be drawn properly without a need for sign bits.
+ ** Function "code_to_ucoord()" transforms these coordinates into
+ ** actual user coordinates.
+ **
+ ** Example: code for character 'L': "\032\224\324" translates to:
+ ** moveto(1,10); drawto(1,4); drawto(5,4);
+ **
+ ** From the example you can conclude that the font below essentially is
+ ** defined on a 5x7 grid:
+ **
+ ** 0 1 2 3 4 5 6 7
+ ** 15 . . . . . . . . . : unused
+ ** 14 . . . . . . . . * : always used
+ ** 13 . . . . . . . . o : sometimes used
+ ** 12 . . . . . . . .
+ ** 11 . . . . . . . .
+ ** 10 o * * * * * . .
+ ** 9 o * * * * * . .
+ ** 8 o * * * * * . .
+ ** 7 o * * * * * . .
+ ** 6 o * * * * * . .
+ ** 5 o * * * * * . .
+ ** 4 o * * * * * . .
+ ** 3 o o o o o o . .
+ ** 2 o o o o o o . .
+ ** 1 o o o o o o . .
+ ** 0 o o o o o o . .

+ ** The following array of strings contains the ps math font (173),
+ ** which differs from ventura math (205) only in the sequence of
+ ** characters in the upper half of the font
