flash插入页面后在IE下stageWidth为0的bug

用SWFObject，将swf文件嵌入网页后，在IE浏览器中首次浏览正常，刷新后，stageWidth就为0了，swf中基于stageWidth定位的元素，就会错乱。

首先区分一下stage的stageWidth和width属性。stage.stageWidth是flash player的宽度，stage.width是指stage里content的宽度，如果这个舞台(stage)里什么内容都没有，stage.width就是0。
        现在的需求是在运行期获得舞台的高宽，以期编码实现将组件添加到舞台中央等这样的效果。但是我得到的stageWidth 和 stageHeight 都为0。
        对于某个问题，老外的解释总是很详尽：http://hubflanger.com/stage-resize-and-the-stagewidth-and-stageheight-properties/
Turns out that when the stage is initialized, it's stageWidth and stageHeight properties are 0 until a Stage RESIZE event is triggered. This event is dispatched when the scaleMode property of the Stage object is set to StageScaleMode.NO_SCALE and the SWF file is resized ie. when the stage is rendered by the Flash Player. So if you need to add a display object onto the stage and its positioning is dependent on the stageWidth or stageHeight properties at runtime, it’s best handled by a listener that is subscribed to the Stage RESIZE event.
       在IE中SWF文件的stageWidth 和 stageHeight 被初始化为0，再延迟一段时间后会更新成正确的数值。在SWF文件更新stageWidth 和 stageHeight属性时，会触发stage对象的resize事件。因此， 可以给stage添加resize事件处理器，将取得stageWidth 和 stageHeight值及后续工作放在resize处理函数里做，一旦stageWidth 和 stageHeight值大于0，则将此resize监听器取消掉。
Interestingly, despite universal claim that the Flash Player behaves exactly the same on all browsers, this problem only appears in a couple of browser/plugin configurations, namely FireFox/OSX and IE/Win. And strangely, on Safari and Firefox/Win, the RESIZE event is not even dispatched on page load, and neither does the Flash Player register the stageWidth and stageHeight properties as bein
