The spec allows unrequested backing store, and actually explicitly states that backing store should not preserve window contents obscured by inferior windows, so the current implementation is actually incorrect. My intent is to make backing store per heirarchy, clipped to the window with backing store set; that should make translucent windows possible, although it will take some work to get the region of the parent preserved. There are other changes in the 5.0 driver design to hide the window heirarchy from the hardware drivers which should make some of this easier to accelerate, right now it would be a bit convoluted.
