Technical commit: I've changed the puck's X,Y coordinates from 8-bit integers in the range of 0-255, to 16-bit in the range 0-511. Along with one less division in the delta X/Y, this allows for twice the precision of movement.
In simple terms, it allows for the equivalent of having deltas 0, 0.5, 1, 1.5, 2, 2.5, 3 delta X/Y instead of only 0-1-2-3
