Avoid scaling overlays on systems that don't support them.

Most systems that only support direct (unscaled) overlays are Intel
Cherry Trail. On these systems we want to make sure overlay swapchains
are the size they appear onscreen, so that no scaling is necessary.
Otherwise they may be displayed using compositing in DWM, which can be
much less efficient.
