  * DDSCL_NORMAL is not compatible with DDSCL_EXCLUSIVE or DDSCL_FULLSCREEN
  * DDSCL_SETFOCUSWINDOW can be passed only in DDSCL_NORMAL mode, but after that

  *  DDSCL_SETDEVICEWINDOW: Sets a window specially used for rendering (I don't
  *  expect any difference to a normal window for wine)
  *  DDSCL_CREATEDEVICEWINDOW: Tells ddraw to create its own window for

  * The reason is that the IWineD3DSwapchain(render target container)
  * and the IWineD3DTexure(Texture container) release the parents
  * of their surface's children, but by releasing the complex root
  * the surfaces which are complexly attached to it are destroyed
  * too. See IDirectDrawSurface::Release for a more detailed
  * explanation.
  *
  * Params:
  *  DDSD: Description of the surface to create
  *  Surf: Address to store the interface pointer at
  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
  *            aggregation, so it has to be NULL
  *
  * Returns:
  *  DD_OK on success
  *  CLASS_E_NOAGGREGATION if UnkOuter != NULL
  *  DDERR_* if an error occurs
