2099  * IDirectDraw7::CreateSurface
2100  *
2101  * Creates a new IDirectDrawSurface object and returns its interface.
2102  *
2103  * The surface connections with wined3d are a bit tricky. Basically it works
2104  * like this:
2105  *
2106  * |------------------------|               |-----------------|
2107  * | DDraw surface          |               | WineD3DSurface  |

2110  * |        Child           |<------------->| Parent          |
2111  * |------------------------|               |-----------------|
2112  *
2113  * The DDraw surface is the parent of the wined3d surface, and it releases
2114  * the WineD3DSurface when the ddraw surface is destroyed.
2115  *
2116  * However, for all surfaces which can be in a container in WineD3D,
2117  * we have to do this. These surfaces are usually complex surfaces,
2118  * so this concerns primary surfaces with a front and a back buffer,
2119  * and textures.
2120  *

2154  *  |             ---More surfaces can follow---                  |

2156  * The reason is that the IWineD3DSwapchain(render target container)
2157  * and the IWineD3DTexure(Texture container) release the parents
2158  * of their surface's children, but by releasing the complex root
2159  * the surfaces which are complexly attached to it are destroyed
2160  * too. See IDirectDrawSurface::Release for a more detailed
2161  * explanation.
2162  *
2163  * Params:
2164  *  DDSD: Description of the surface to create
2165  *  Surf: Address to store the interface pointer at
2166  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2167  *            aggregation, so it has to be NULL
2168  *
2169  * Returns:
2170  *  DD_OK on success
2171  *  CLASS_E_NOAGGREGATION if UnkOuter != NULL
2172  *  DDERR_* if an error occurs
