First a fast way to read the data off disk to begin with, for start up time.
Then caching of row heights when they are calculated. Finally binary search
of row heights/positions when mapping coordinates to row indexes.
Of course depending on what calculations are truly necessary, the first draw
may still be slow, but there's really no reason a redraw should be slow
after changing one (or a few) values.
