+ *  @see CAlfVisual::EnableDropShadowL
+ *  @see CAlfVisual::DropShadowHandler

+ *  @code
+ *   // get the pointer
+ *   visual->EnableDropShadowL();

+ *
+ *  Disabling the drop shadow from the visual, deletes the instance and therefore loses
+ *  all set paramteres. If you want to just hide the drops shadow temporally, you can 
+ *   a) set the opacity into 0 or
+ *   b) set the scale into 0
