Ball is displayed by combining two sprite pieces. Because of this, you need to change

If the Texture Filter is PointSample, you don't have to specify SHRINKSIZE; but, If it
is Bilerp, it must be SHRINKSIZE_1. When you specify SHRINKSIZE_1, the circumference
of Sprite for 0.5 texel is clamped. The area excepted by this clamp becomes a part
that the Bilerp process gives no effect.
Because you need to load the part of adjoining of Sprite twice in Bilerp, Ball draws
only for 64x63 texels. It is important to understand the differences between
objBall[1] and objBall[2] well.
