2095  * IDirectDraw7::CreateSurface
2096  *
2097  * Creates a new IDirectDrawSurface object and returns its interface.
2098  *
2099  * The surface connections with wined3d are a bit tricky. Basically it works
2100  * like this:
2101  *
2102  * |------------------------|               |-----------------|
2103  * | DDraw surface          |               | WineD3DSurface  |
2104  * |                        |               |                 |
2105  * |        WineD3DSurface  |-------------->|                 |
2106  * |        Child           |<------------->| Parent          |
2107  * |------------------------|               |-----------------|
2108  *
2109  * The DDraw surface is the parent of the wined3d surface, and it releases
2110  * the WineD3DSurface when the ddraw surface is destroyed.
2111  *
2112  * However, for all surfaces which can be in a container in WineD3D,
2113  * we have to do this. These surfaces are ususally complex surfaces,
2114  * so this concerns primary surfaces with a front and a back buffer,
2115  * and textures.
2116  *

2150  *  |             ---More surfaces can follow---                  |
2151  *
2152  * The reason is that the IWineD3DSwapchain(render target container)
2153  * and the IWineD3DTexure(Texture container) release the parents
2154  * of their surface's children, but by releasing the complex root
2155  * the surfaces which are complexly attached to it are destroyed
2156  * too. See IDirectDrawSurface::Release for a more detailed
2157  * explanation.
2158  *
2159  * Params:
2160  *  DDSD: Description of the surface to create
2161  *  Surf: Address to store the interface pointer at
2162  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2163  *            aggregation, so it has to be NULL
2164  *
2165  * Returns:
2166  *  DD_OK on success
2167  *  CLASS_E_NOAGGREGATION if UnkOuter != NULL
2168  *  DDERR_* if an error occurs
