;;                             |
;;  +--------------------------+
;;  |
;;  V
;; Contains one or more (autotileset ... )
;;                                    |
;;  +---------------------------------+
;;  |
;;  V
;; Contains :
;;   The autotileset name (unused as of writing these lines) : (name "snow")
;;     The name of the autotileset is "snow".
;;   The default tile ID (used if no tile matches any mask) : (default 11)
;;     If a very special tile is needed (and it doesn't exist), it will use this tile (it's a center tile) by default.
;;   Many (autotile ... )
;;                   |
;;  +----------------+
;;  |
;;  V
;; Contains :
;;   The ID of the tile : (id 11)
;;   Whether or not the tile is solid (see the "mask" part below) : (solid #t)
;;   One or more (mask "000111**") - see below alt-id for info
;;   One or more (alt-id ... )
;;                        |
;;  +---------------------+
;;  |
;;  V
;; Contains :
;;   The alternative id : (id 123456)
;;   The weight : (weight 0.2)
;;     The weight is the odds of this tile to happen. 0 is never, 1 is always.
;;     The autotile's default ID's odds of occuring are (1 - sum of all weights).
;;     Ideally, the sum of all weights for an autotile should be below 1. If it
;;     is 1, the the regular ID for that autotile will never occur. If it is
;;     greater than 1, then certains alt ID's might never occur either.
;;
;; ===== MASK INFO =====
;;
;; The mask is 8 characters and represent which tiles around it is solid.
;; The characters represent, in order :
;;   1st : The tile on the top-left
;;   2nd : The tile on top
;;   3rd : The tile on the top-right
;;   4th : The tile on the left
;;         /* There is no number for the center (the tile itself); the "solid" property is there for that */
;;   5th : The tile on the right
;;   6th : The tile on the bottom-left
;;   7th : The tile below
;;   8th : The tile on the bottom-right
;;
;; Each character can either be :
;;   '0', if the tile at that location must not be solid;
;;   '1', if the tile at that location must be solid;
;;   '*', if the tile at that location may or may not be solid.
;;
;; Example :
;;   "11100*0*"
;;
;; If needed, multiple masks can be used.
;;
;; Example : The tile 3055 (downwards column with "ridges" going both sides) has those two masks :
;;   "11100*0*"
;;   "11100010"
;; ...because "11100010" is valid for that tile, "11100101" is too, but "11100111" isn't. (try it!)

;; NOTE : A single id MUST NOT OCCUR MORE THAN ONE AUTOTILE IN THE ENTIRE FILE.
;;        Otherwise, the behavior is UNDEFINED.
