We discussed in the past about adding a ::redraw method to the Gui class, to
be also used from a menu item.  Can't remember if we did already, if we didn't
consider adding one yourself (you'd call that on expose).

Also, to avoid redrawing as hell while receiving a long chain of expose
events it might be worth having a loop checking for it. IIRC Udo added one
mechanism working at SWF FPS rate (wantsRedraw or similar method) but we might
want an SWF agnostic one. See also the Movie_Advancement page on gnashdev wiki.

Have fun !
