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>
