/*--------------  vision tables  --------------*\
 *
 *  Generate the close and far tables.  This is done by setting up a
 *  fake dungeon and moving our source to different positions relative
 *  to a block and finding the first/last visible position.  The fake
 *  dungeon is all clear execpt for the upper left corner (BLOCK_HEIGHT
 *  by BLOCK_WIDTH) is blocked.  Then we move the source around relative
 *  to the corner of the block.  For each new position of the source
 *  we check positions on rows "kittycorner" from the source.  We check
 *  positions until they are either in sight or out of sight (depends on
 *  which table we are generating).  The picture below shows the setup
 *  for the generation of the close table.  The generation of the far
 *  table would switch the quadrants of the '@' and the "Check rows
 *  here".
 *
 *
 *  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
 *  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
 *  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,,,,,,,,, Check rows here ,,,,,,,,,,,,
 *  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
 *  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXB,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
 *  ...............................
 *  ...............................
 *  .........@.....................
 *  ...............................
 *
 *      Table generation figure (close_table).  The 'X's are blocked points.
 *      The 'B' is a special blocked point.  The '@' is the source.  The ','s
 *      are the target area.  The '.' are just open areas.
 *
 *
 *  Example usage of close_table[][][].
 *
 *  The table is as follows:
 *
 *      dy = |row of '@' - row of 'B'|  - 1
 *      dx = |col of '@' - col of 'B'|
 *
 *  The first indices are the deltas from the source '@' and the block 'B'.
 *  You must check for the value inside the abs value bars being zero.  If
 *  so then the block is on the same row and you don't need to do a table
 *  lookup.  The last value:
 *
 *      dcy = |row of block - row to be checked|
 *
 *  Is the value of the first visible spot on the check row from the
 *  block column.  So
 *
 *  first visible col = close_table[dy][dx][dcy] + col of 'B'
