In DirectFB each window has its own surface thus no window draws directly to the framebuffer. The window surfaces are then composited onto the display layer's back buffer which is copied to the front buffer when the window stack has been repainted. The only point where the translucency of a window is considered is during window stack repaints where this information is used to optimize unnecessary compositing away. I'm however not sure what Keith means exactly when he uses the word "overlay layer". It's most probably unrelated to the DisplayLayer used in DirectFB.
