landInDirection関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The territory a key moves to from another: the nearest counter in that
direction, a little straighter being better than a little nearer, and only
among those inside view (the whole map when none is given), so that the
focus never leaves what is on the screen. Null when nothing lies that way.
