It was 8.0. It's now arbitrarily 18.0. Changing this required adjusting some tests. Adjusting the tests required debugging the tests. Debugging the tests required some tools to help debugging gesture recognizers and gesture arenas, so I added some. It also required updating some toString() methods which resulted in some changes to the tree diagnostics logic. Also I cleaned up some docs while I was at it.
