Subject: public/bluebey-studio: ダリひげを左右半分の画像にして間隔を調整可能に
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hige-2-right（ぶるべーから見て右側のダリ髭）を取り込み、左右それぞれに描いて「左右の間隔」で開きを調整できるようにした。ファイル名が -right.png のものは片側（ミラーして2枚描く）として扱う。

全幅だった kaiser.png は kaiser-right.png に置き換えた。
