/*
Filtering syntax:
Any line NOT starting with a caret is either suppressed or passed through
unchanged depending on the current conditional state.
The default conditional state is printing on.
Conditionals may be nested.
makedefs will exit with a EXIT_FAILURE if any errors are detected; as many
errors as possible are detected before giving up.
Unknown identifiers are treated as TRUE and also as an error to allow
processing to continue past the unknown identifier (note that "#undef" is
different than unknown).
Any line starting with a caret is a control line; as in C, zero or more
spaces
may be embedded in the line almost anywhere; the caret MUST be in column 1.
(XXX for the moment, no white space is allowed after the caret because
existing lines in the docs look like that)
Control lines:
^^ a line starting with a (single) literal caret
^# a comment - the line is ignored
^?ID if defined(ID)
^!ID if !defined(ID)
^: else
^. endif

/*-------------- 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'
