Interesting... It seems to me tidy would work better if it simply
checked first if it had objects that are vertically or horizontally
closer to its x,y position and then adjust according to them only,
rather than keeping a HIST of values it may be able to potentially
adjust to. This would of course require change to the algorithm's
fundamentals. Another thought would be to have the whole thing keep
running with ever-increasing thresholds until something is adjusted or
some ridiculous threshold is reached.
