/** @language english
* Initializes a LBitmap object to refer to the specified LBitmapData object.
* The LBitmap class represents display objects that represent bitmap images. These can be images that you load with the LLoader class, or they can be images that you create with the LBitmap() constructor.
* The LBitmap() constructor allows you to create a Bitmap object that contains a reference to a BitmapData object. After you create a LBitmap object, use the addChild() or addChildAt() method of the parent instance to place the bitmap on the display list.
* A LBitmap object can share its BitmapData reference among several Bitmap objects, independent of translation or rotation properties. Because you can create multiple LBitmap objects that reference the same BitmapData object, multiple display objects can use the same complex BitmapData object without incurring the memory overhead of a BitmapData object for each display object instance.
* A LBitmapData object can be drawn to the screen by a LBitmap object in one of two ways: by using the vector renderer as a fill-bitmap shape, or by using a faster pixel-copying routine. The pixel-copying routine is substantially faster than the vector renderer.
* The LBitmap class is not a subclass of the InteractiveObject class, so it cannot dispatch mouse events. However, you can use the addEventListener() method of the display object container that contains the LBitmap object.
* @class LBitmap
* @extends LDisplayObject
* @constructor
* @param {LBitmapData} bitmapData The LBitmapData object being referenced.
* @example
* Linit(50, "mylegend", 800, 480, main);
* function main () {
* var loader = new LLoader();
* loader.addEventListener(LEvent.COMPLETE, loadBitmapdata);
* loader.load("lufylegend.js.png", "bitmapData");
* }
* function loadBitmapdata (event) {
* var bitmapdata = new LBitmapData(event.currentTarget);
* var bitmap = new LBitmap(bitmapdata);
* addChild(bitmap);
* }
