// 必要なもの：
//	
//	ラベル：surfaceも貼れた方がよいが、まあいいや
//	ラベル位置：ボタンの上、もしくは右
//		右の場合：右中央へjustify するので、ラベル全体の幅と右マージンが必要
//		上の場合：左下へjustify するので、左マージンと下マージンが必要

//	内容：x,y個数を指定、その中で中央割り当て

//		ラベル位置情報：上なら左下にjustify, 右なら右中央にjustify
//		なので、下へのマージンと上へのマージン、
//	ラベル＋四角ボタン（チェックボックス）
//		ボタンが押されるとdeactivateされる
//
//	ラジオボタン
//		テキストボタンの集合体。x,y の個数を指定
//	スケール
