	It is sometimes more useful to know the height of the highest corner of the tile. This can be computed with "zz/8 + ((ss+15)/16)", that is: "60 XX 33 1F 00 60 XX 40 FF 0F 10", where XX is the parameter. This returns a number 0..31 instead of 0..248, though.		{{grfTill\|7}} It is sometimes more useful to know the height of the highest corner of the tile.
