Always give overlay scrollbars their own layers, even for subframes
We currently don't create individual layers for subframe scrollbars, since subframes usually have a thebes layer behind them that spans the whole scroll port, and the scrollbars can merge into that background layer. However, this is not the case for overlay scrollbars: Overlay scrollbars cause a new thebes layer to be created in front of the scrolled layer, and if both horizontal and vertical scrollbars are visible, that front layer is much larger than necessary.
Huh, aCreateLayer was a reference...
