The reason the 2600 positions objects as it does is because poly-counter
logic is cheaper to implement than digital logic.  Believe me, they did
weigh the alternatives.  At the time it saved a significant amount of
money and since they developed a software conversion routine and were
anticipating that this routine, albeit CPU-hungry, would only be necessary
once at the top of the frame for each sprite (hence not knowing about the
HMOVE comb bug) it didn't seem like a big compromise.
