I guess I should have read the version 2 test before hitting "send"...

The v2 behavior is somewhat weird. What's even weirder is that you
didn't need any todo_wine to make it work in Wine (whereas you need the
todo_wine for the "sane" v1 behavior). Our DeleteAttachedSurface
implementation sets the wined3d DS to NULL, at which point a
D3DCLEAR_ZBUFFER clear should return an error. Do you have any idea why
the depth buffer is still cleared on Wine?
