2227 *
2228 * The reason is that the IWineD3DSwapchain(render target container)
2229 * and the IWineD3DTexure(Texture container) release the parents
2230 * of their surface's children, but by releasing the complex root
2231 * the surfaces which are complexly attached to it are destroyed
2232 * too. See IDirectDrawSurface::Release for a more detailed
2233 * explanation.
2234 *
2235 * Params:
2236 * DDSD: Description of the surface to create
2237 * Surf: Address to store the interface pointer at
2238 * UnkOuter: Basically for aggregation support, but ddraw doesn't support
2239 * aggregation, so it has to be NULL
2240 *
2241 * Returns:
2242 * DD_OK on success
2243 * CLASS_E_NOAGGREGATION if UnkOuter != NULL
2244 * DDERR_* if an error occurs
