/**
* A simple Component for displaying an Adobe Flash SWF movie. The movie will be sized and can participate
* in layout like any other Component.
*
* This component requires the third-party SWFObject library version 2.2 or above. It is not included within
* the ExtJS distribution, so you will have to include it into your page manually in order to use this component.
* The SWFObject library can be downloaded from the [SWFObject project page](http://code.google.com/p/swfobject)
* and then simply import it into the head of your HTML document:
*
* <script type="text/javascript" src="path/to/local/swfobject.js"></script>
*
* ## Configuration
*
* This component allows several options for configuring how the target Flash movie is embedded. The most
* important is the required {@link #url} which points to the location of the Flash movie to load. Other
* configurations include:
*
* - {@link #backgroundColor}
* - {@link #wmode}
* - {@link #flashVars}
* - {@link #flashParams}
* - {@link #flashAttributes}
*
* ## Example usage:
*
* var win = Ext.widget('window', {
* title: "It's a tiger!",
* layout: 'fit',
* width: 300,
* height: 300,
* x: 20,
* y: 20,
* resizable: true,
* items: {
* xtype: 'flash',
* url: 'tiger.swf'
* }
* });
* win.show();
*
* ## Express Install
*
* Adobe provides a tool called [Express Install](http://www.adobe.com/devnet/flashplayer/articles/express_install.html)
* that offers users an easy way to upgrade their Flash player. If you wish to make use of this, you should set
* the static EXPRESS\_INSTALL\_URL property to the location of your Express Install SWF file:
*
* Ext.flash.Component.EXPRESS_INSTALL_URL = 'path/to/local/expressInstall.swf';
*
