[Laszlo-dev] Modifying someView.sprite.__LZdiv.innerHTML

Thu Aug 20 16:02:32 PDT 2009

view.getMCRef() just delegates to view.sprite.getMCRef() - similar to 
view.setWidth() delegating to view.sprite.setWidth().  It's a style 
thing - we only support methods that can be called from within the view 
system.
