//测试如何调用 lua 中graySprite的方法

	//Filter*gg = GrayFilter::create(Color4F(0,1,0.5)); //变灰，颜色值变，灰度也变
	//Filter*gg = HueFilter::create(0);//无效果，似乎没有任何用
	//Filter*gg = BrightnessFilter::create(0.6); //效果为：让图片明亮一些，缺点是整张图都变亮了
	//Filter*gg = SaturationFilter::create(1);//更改图片饱和度，0的时候似乎全部变灰，1为正常
	//Filter*gg = ContrastFilter::create(0.5);//更改对比度
	//Filter*gg = ExposureFilter::create(1);//更改曝光度
	//Filter*gg = GammaFilter::create(1);//
	//Filter*gg = HazeFilter::create(0.5,0);// 第一个雾距  第二个 边坡 肯能由于地图山地类型使用
	//Filter*gg = SepiaFilter::create(1);// 分辨率

lua 中的写法类似，如下：

    display.newGraySprite("button.png"):align(display.CENTER,display.cx,display.cy):addTo(self)

    local spFrame = cc.SpriteFrame:create("button.png",cc.rect(0,200,200))

    local gfilter = cc.GrayFilter:create(cc.c4f(1,0.5))
    local sp=cc.FilteredSpriteWithOne:createWithSpriteFrame(spFrame); 
    sp:setFilter(gfilter)
    sp:setPosition(display.cx,200)
    self:addChild(sp)
