Some input method can generate different input depends on text before or after input cursor.

And some input method can also reconvert committed text or selected text to some others.

For example, the mozc input method can also reconvert committed text input Hiragana or Katakana, and etc.

This API is for getting the surrounding text and anchor, cursor position in surrounding text.
