auto resizeDown         = cocos2d::ResizeTo::create(2.8f,Size(50,40));
auto resizeUp           = cocos2d::ResizeTo::create(2.8f,Size(300,40));

auto scaleDownScale     = cocos2d::ScaleTo::create(2.8f,1.0f);
auto scaleUpScale       = cocos2d::ScaleTo::create(2.8f,6.0f,1.0f);

这两种情况下推荐使用ResizeTo,如果用ScaleTo会导致图形在变大过程中边缘模糊。
