This may be ok, but note that the test doesn't actually test this.
(E.g. does calling SetSurfaceDesc() with the original surface desc
work? What about bits not in DDSD_ALL? Etc.) Also, as a general
principle, I'd be happier about the ddraw tests if they actually
tested all the different interface versions.
