This removes the capability of having differently-sized vertical and horizontal scrollbars (which is only potentially used in windows, and in practice almost-never used). For that case, we choose the larger of vertical/horizontal scrollbar sizes. This is in order to be able to realistically expose the scrollbar size to CSS, see blocked bug. We make RecomputeScrollbarParams the central place where each scrollbar style decides its sizes, and make GetDPIRatioForScrollbarPart handle the cocoa special-case of scaling to 1 or 2, but nothing else.
