Save ConfigureNotify events for unmapped windows until the window maps. If a window moves while it is unmapped, it should not affect its fade-out. 

A window can move/resize while it is fading out.  Even if you don't delete the pixmap in that case, the fade-out will be shown in the wrong place and the wrong area on screen will be marked damaged when the window is gone without this patch.
