I gave the visual test suite a shot, normal test run on my Windows 7 x64:
visual.c:196: Driver string: "atiumdag.dl
visual.c:197: Description string: "ATI Ra
visual.c:199: Device name string: "\\.\DI
visual.c:201: Driver version 8.14.10.678
----
visual: 5493 tests executed (0 marked as todo, 75 failures), 3 skipped.

now, changing the code in create_window to return GetDesktopWindow(), gives

visual.c:196: Driver string: "atiumdag.dl
visual.c:197: Description string: "ATI Ra
visual.c:199: Device name string: "\\.\DI
visual.c:201: Driver version 8.14.10.678
----
visual: 5493 tests executed (0 marked as todo, 75 failures), 3 skipped.

There's only 1 difference, the first one really shows a window with
all the triangle's, like it should. Second one doesn't show anything.
So all the functions don't fail, they just don't seem to do anything.
