+/**
+ * BitmapAsset is a subclass of the flash.display.Bitmap class
+ * which represents bitmap images that you embed in a Flex application.
+ * It implements the IFlexDisplayObject interface, which makes it
+ * possible for an embedded bitmap image to be displayed in an Image control,
+ * or to be used as a container background or a component skin.
+ *
+ * <p>The bitmap image that you're embedding can be in a JPEG, GIF,
+ * or PNG file.
+ * You can also embed a bitmap symbol that is in a SWF file produced
+ * by Flash.
+ * In each of these cases, the MXML compiler autogenerates a class
+ * that extends BitmapAsset to represent the embedded bitmap image.</p>
+ *
+ * <p>You don't generally have to use the BitmapAsset class directly
+ * when you write a Flex application.
+ * For example, you can embed a GIF file and display the image
+ * in an Image control by writing the gollowing:</p>
+ *
+ * <pre>
+ * <mx:Image id="logo" source="@Embed(source='Logo.gif')"/></pre>
+ *
+ * <p>or use it as the application's background image in CSS syntax
+ * by writing</p>
+ *
+ * <pre>
+ * <fx:Style>
+ * @namespace mx "library://ns.apache.org/royale/mx"
+ * mx|Application {
+ * backgroundImage: Embed(source="Logo.gif")
+ * }
+ * <fx:Style/></pre>
+ *
+ * <p>without having to understand that the MXML compiler has created
+ * a subclass of BitmapAsset for you.</p>
+ *
+ * <p>However, it may be useful to understand what is happening
+ * at the ActionScript level.
+ * To embed a bitmap image in ActionScript, you declare a variable
+ * of type Class, and put <code>[Embed]</code> metadata on it.
+ * For example, you embed a GIF file like this:</p>
+ *
+ * <pre>
+ * [Bindable]
+ * [Embed(source="Logo.gif")]
+ * private var logoClass:Class;</pre>
+ *
+ * <p>The MXML compiler sees the .gif extension, transcodes the GIF data
+ * into the bitmap format that the player uses, autogenerates
+ * a subclass of the BitmapAsset class, and sets your variable
+ * to be a reference to this autogenerated class.
+ * You can then use this class reference to create instances of the
+ * BitmapAsset using the <code>new</code> operator, and you can use
+ * APIs of the BitmapAsset class on them:</p>
+ *
+ * <pre>
+ * var logo:BitmapAsset = BitmapAsset(new logoClass());
+ * logo.bitmapData.noise(4);</pre>
+ *
+ * <p>However, you rarely need to create BitmapAsset instances yourself
+ * because image-related properties and styles can simply be set to an
+ * image-producing class, and components will create image instances
+ * as necessary.
+ * For example, to display this image in an Image control, you can
+ * set the Image's <code>source</code> property to <code>logoClass</code>.
+ * In MXML you could do this as follows:</p>
+ *
+ * <pre>
+ * <mx:Image id="logo" source="{logoClass}"/></pre>
+ *
+ * @langversion 3.0
+ * @playerversion Flash 9
+ * @playerversion AIR 1.1
+ * @productversion Flex 3
