Fix a bug in the ease{In,Out}Bounce easing functions + small cleanup.
The bug was in easeOutBounce_helper(), where the last else-block
adjusted t wrong. It should adjust t so that the peak is at t == 0,
but it adjusted it too little.
The old code did t -= (2.25f/2.75f), but it should have been 21/22.
The rest of the changes in that function is just simple mathematical
rewrites (use a more readable fraction), and removed the b argument,
since that was always 0.
Finally, fixing the original bug also revealed a bug in the first
line of easeOutBounce_helper(), where we always returned
1.0 for t == 1.0. That was wrong since it did not respect c.
