tile value = base-10 number,  1-digit,  chip wrap-around index, starting at Zero.
RPG Maker chipsets are 30 tiles wide...
... so a tile value of 30 would select the far-left chipset tile on line 2.
	var id = map.layers[l][x][y];
	var xChipTile = id % chipWidth;
	var yChipTile = Math.floor( id / chipWidth );
