Some comments of codes are wrong

[github2016-yuan]

In method of renderResult()

(1)// if no effect is chosen, just render the original bitmap
mTexRenderer.renderTexture(mTextures[1]);

should be
// render the result of applyEffect()
mTexRenderer.renderTexture(mTextures[1]);

(2) // render the result of applyEffect()
mTexRenderer.renderTexture(mTextures[0]);

should be
// if no effect is chosen, just render the original bitmap
mTexRenderer.renderTexture(mTextures[0]);
