             * GRIDSET uses LTDEF


 Characters in the scroll text are drawn using lines on a 3x6 numbered grid
 like this:

   0   1   2
   .   .   .
   3   4   5
   .   .   .
   6   7   8
   9   A   B

 The low nibble of each byte is the starting point for that line segment, and
 the high nibble is the end point, so a value of $28, for example, means
 "draw a line from point 8 to point 2". This table contains definitions for all
 the characters we can use in the scroll text, as lines on the above grid.
