1:聚光灯效果：
实例：http://www.rphelan.com/flex/SpotlightDemo/SpotlightDemo.html
ambientColor - color to apply to all pixels of the image
angle - angle at which the spotlight is projected (in degrees)
azimuth - angle between the image plane and the spotlight (in degrees)
coneAngle - angle of the spotlight's "opening" (in degrees)
distance - distance from the spotlight to the center point
intensity - intensity of the spotlight
position - x, y, z position of the spotlight
spotColor - color of the spotlight

2:放大镜效果：
实例：http://www.rphelan.com/flex/MagnifyDemo/MagnifyDemo.html
center ([0-2048, 0-2048]) - the center coordinates of the magnified area
outerRadius (0-500) - the radius of the magnified part of the image
innerRadius (0-500) - the radius of the fully magnified part of the image
magnification (1-50) - the amount to magnify the image by (e.g. set to 2 for a 2x magnification)

3：缩放模糊效果：
实例：http://www.rphelan.com/flex/ZoomBlurDemo/ZoomBlurDemo.html
amount (0 - 0.5) - the amount of blur to apply
center ([0 - 2048, 0 - 2048]) - the focal point of the blur

4：浮雕效果：
实例：http://www.rphelan.com/flex/SharpenDemo/SharpenDemo.html
amount (0 - 20) - the amount to sharpen the image by
radius (0 - 1) - pixel distance to sample from

5：水波效果：
实例：http://www.rphelan.com/flex/WaveReflectionDemo/WaveReflectionDemo.html
amplitude (0-1) - the height of the waves
frequency (0-.54) - how close together the waves are. Higher value = more waves.
progress (0-1) - percentage of the wave sequence. Animate from 0 to 1 to get a smooth wave effect.

flash.util.Timer类
flash.util.Timer类允许通过添加时间事件或延时来调用方法。通过Timer构造器创建实例对象，传递一个毫秒数字作为构造参数作为间隔时
间，下面的例子实例化一个Timer对象每个1秒钟发出事件信号：
var timer.Timer = new Timer(1000);
