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

  * Unhandled flags, which should be implemented
  *  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
  *  rendering (Possible test case: Half-life)

  * These don't seem very important for wine:
  *  DDSCL_ALLOWREBOOT, DDSCL_NOWINDOWCHANGES, DDSCL_ALLOWMODEX

  * The surface connections with wined3d are a bit tricky. Basically it works

  *
  * |------------------------|               |-----------------|
  * | DDraw surface          |               | WineD3DSurface  |

  * |------------------------|               |-----------------|
  *
  * The DDraw surface is the parent of the wined3d surface, and it releases
  * the WineD3DSurface when the ddraw surface is destroyed.
  *
  * However, for all surfaces which can be in a container in WineD3D,
  * we have to do this. These surfaces are usually complex surfaces,
  * so this concerns primary surfaces with a front and a back buffer,
  * and textures.

  * 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
