用AS来调整图片的色调、亮度、灰度、饱和度、对比度、反相虽然不难，但因为涉及到ColorMatrixFilter的颜色矩阵的应用，使用起来有点麻烦，因此写了这个类ColorProperty。
这个类是对MovieClip类扩展，为MovieClip增加了这些属性：
色调:_color
亮度:_brightness
灰度:_grayscale
饱和度:_saturation
对比度:_contrast
反相:_invert
当然，你也可以改写这个类，使之成为一个新类，而不是扩展MovieClip类。
用法（与_width,_height用法一样）：
importColorProperty;
ColorProperty.init();
//色调，用如0xFF0000的16进制
//img._color=0x333399;
//trace(img._color);
//亮度，取值范围为：-255~255
img._brightness=100;
//trace(img._brightness)
//灰度，布尔值，true为灰度，false则反之。
//img._grayscale=true;
//trace(img._grayscale);
//饱和度，一般范围为：0~3为宜
//img._saturation=3;
//trace(img._saturation);
//对比度，取值范围为：0~1
//img._contrast=0.15;
//反相，布尔值，true为反相，false则反之。
//trace(img._contrast);
//img._invert=true;
代码如下：
