createSqr()：さいころの各面を描写する。
arrangeSqr()：各面のゼロ点を、面の対角線の交点に移動し、各面を組み合わせてさいころを作る。
rotateHex()：マウスの座標に対応した X 、 Y 軸に沿った回転を行う。
hexSetOrder()：Vector3Dクラスを利用して、さいころの中心から各面の対角線交点までの Z 座標を比較してレイヤーを入れ替える。

/*Each of the faces of the cube is created in the function
*createSqr(). This also puts white eyes on each of the
*faces (line 61).
*
*The origin of each of these faces is moved to the point
*of intersection of diagonals of the square faces by being
*caged in other Sprites (line 43, 56, 57).
*
*The arrangeSqr() arranges the faces in a Sprite (hex) for
*proper angles and coordinates to make dice.
*
*When cursor moves, the distance to the center of the
*dice is used to change the angle of rotation of the dice
*by rotateHex() (line 101).
*
*In hexSetOrder(), the distance along z axis between the
*center of the dice and the point of intersection of
*diagonals of each of the faces are compared with each
*other to rearrange the layers.
