+/**
+ * CHuiImageLoaderUtil is a utility class to create image loader with the system skin 
+ * applied. CHuiImageLoaderUtil holds all MHuiBitmapProvider instance created through
+ * CreateImageLoaderL() so that appplication/control does not need to keep it by itself.
+ * 
+ * Typically, an application or a control needs to hold instance of CHuiImageLoaderUtil
+ * during entire its object life time, because bitmap provision callback from texture
+ * manager may be called even after instanciation of texture. For instance, image re-loading
+ * happens when application coming back to foreground and resource was released.
