-- The Minetest engine gives us 256 palette indexes to work with. For
-- this particular mod, we don't need quite that many though. Much of
-- he functionality of this mod assumes that the palette index of the
-- node defined in this mod will always have an item name associated
-- with it, and that'd be a valid assumption, considering that this mod
-- will never grant players a copy of the node with an "unused" index.
-- However, other mods might change the param2 value for a node, or
-- perhaps give players new copies of nodes with palette indexes
-- outside the expected range. For this reason, among others, all
-- palette indexes have been assigned an item. Under normal
-- circumstances, you'll see less than an eighth of these indexes
-- actually used in the world, but having them defined prevents
-- unexpected behaviour. That said, other mods shouldn't be messing
-- with param2 values of nodes they're not familiar with, and changing
-- the param2 value of one of these nodes (or generating a new node
-- with an odd palette index) isn't recommended, and with the valid
-- value lost, a random item will become associated with the
-- newly-indexed node based on its new index.
-- 
-- Some of these items were never obtainable and/or are no longer
-- defined in the game. That doesn't really matter. Random strings
-- could have been associated with the unused indexes so long as they
-- were in the format valid for item names.
