25/**
26 * Since {@link FloatingActionButton} is possibly the worst widget supported by the framework, we
27 * need this class to work around several of it's bugs.
28 *
29 * <p>Current fixes:
30 *
31 * <ul>
32 *   <li>Being able to trigger click events twice.
33 *   <li>Banning setVisibility since 9 times out of 10, it just causes bad state.
34 * </ul>
35 *
36 * Planned fixes:
37 *
38 * <ul>
39 *   <li>Animating on first show/hide
40 *   <li>Being able to call show/hide rapidly and being in the proper state
41 *   <li>Having a proper 48x48 touch target in mini mode
42 * </ul>
