View::take_focus documentation is unclear

The documentation for View::take_focus should reflect on the fact that returning `Ok(EventResult::Ignored)` will not grant focus to the view.

```
Attempt to give this view the focus.

source indicates where the focus comes from. When the source is unclear (for example mouse events), Direction::none() can be used.

Returns Ok(_) if the focus was taken. Returns Err(_) if this view does not take focus (default implementation).
```

The above snippet makes it seem like returning Ok(EventResult::Ignored) will grant focus to the view, but experiments show that one should actually return Ok(EventResult::Consumed(_)) to make the view grab focus. Which begs the question: why are there two ways to ignore focus?
