Subject: public/bluebey-studio:
 寝ているポーズと鼻ちょうちんを追加し、動きを修正
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ポーズ例に「ねている」を追加（体を横に倒した姿勢）
- 「顔」タブに「鼻ちょうちん」を追加。鼻の横に泡を描き、大きさ・位置
 ・色を調整できる。寝ている顔に使う
- 「歩く」の腕と脚の位相を逆にし、右手が前に出るときは左足が前に出る
  ように修正
- 「てをふる」の腕の上げ幅を抑え、手が顔にめり込まないように修正
