--- This mod adds light-emmiting diods to the game.
-- The Pixel concept consist of a Diod (originally the Lamp)
-- and the colored tile under it. By replacing the tile based
-- on lamp color the pixels can be seen on the map in real-time.
-- Updates happening every 4 ticks, but on 3rd tick the regular
-- check-up happening. During this procedure, mod searches for
-- those pixels that changed thair color since last check-up
-- and add those to the Redraw_Queue which will be interated
-- on 4th tick and redrawn.
