>
>Technical Reviewer: promanik

>Documentation:
>
>Release Notes: Setting the cachebitmap attribute to true will tunr 
>on bitmap caching for views.  Note that text defaults to 
>cachebitmap='true'.  This currently works only in Flash.
>
>Details: lfc.lzx - Add setter method and attribute name.
>
>swf/LzTextSprite.as - Default  cachebitmap to true instead of 
>setting directly.
>
>swf/LzSprite.as - Set bitmapcaching capability to true.  Turn off 
>bitmap caching for clipped views, and warn in $debug mode.  Add
>setBitmapCache()  and getContext() implementations.
>
>dhtml/LzSprite.js - Set bitmapcaching capability to false.  Add
>getContext() placeholder method.
>
>swf9/LzSprite.as - Set bitmapcaching capability to true.  Add
>setBitmapCache()  and getContext() implementations.  Update 
>getMCRef() to return the proper reference.
>
>LaszloView.lzs - Add cachebitmap class attribute and setter.
>
>drawview.lzx - Use inherited cachebitmap property.  Default 
>cachebitmap to true.  Use sprite.getContext() API to get graphics 
>context.  Rely on sprite warnings when clipping is on and cachebitmap is true.
>
>
>
>Tests: /test/drawing/drawing.lzx runs as it did before in swf 7,8,9 and dhtml.
