Unfortunately that approach doesn't remove the need for additional windows to draw the reliefs - at least for windows with a background pixmap set. We still can't draw into the pixmap itself, and there is no general way to make one big window with transparent holes that show the background pixmap (at least if we don't want to draw on the foreground of the windows). I'm still digging through the documentation of all that gravity stuff.
