Fwiw, the only non video player app that uses overlays that I know is
settlers 3, which uses them to draw the mouse pointer if certain
options are set.

(Feel free to completely ignore this concern, I don't think overlays
should be a side quest for CSMT...)

Yeah, it probably belongs in the swapchain in some form. I originally
considered moving it entirely into ddraw, which shouldn't be too hard,
but DXGI 1.3 seems to support some form of overlays, and there's also
a small chance we'll want to use OpenGL overlays, so in the end I
decided to just stick with what we currently have until we need
something better.
