2093  * IDirectDraw7::CreateSurface
2094  *
2095  * Creates a new IDirectDrawSurface object and returns its interface.
2096  *
2097  * The surface connections with wined3d are a bit tricky. Basically it works
2098  * like this:
2099  *
2100  * |------------------------|               |-----------------|
2101  * | DDraw surface          |               | WineD3DSurface  |
2102  * |                        |               |                 |
2103  * |        WineD3DSurface  |-------------->|                 |
2104  * |        Child           |<------------->| Parent          |
2105  * |------------------------|               |-----------------|
2106  *
2107  * The DDraw surface is the parent of the wined3d surface, and it releases
2108  * the WineD3DSurface when the ddraw surface is destroyed.
2109  *
2110  * However, for all surfaces which can be in a container in WineD3D,
2111  * we have to do this. These surfaces are ususally complex surfaces,
2112  * so this concerns primary surfaces with a front and a back buffer,
2113  * and textures.
2114  *

2147  *  |                                                             |
2148  *  |             ---More surfaces can follow---                  |
2149  *
2150  * The reason is that the IWineD3DSwapchain(render target container)
2151  * and the IWineD3DTexure(Texture container) release the parents
2152  * of their surface's children, but by releasing the complex root
2153  * the surfaces which are complexly attached to it are destroyed
2154  * too. See IDirectDrawSurface::Release for a more detailed
2155  * explanation.
2156  *
2157  * Params:
2158  *  DDSD: Description of the surface to create
2159  *  Surf: Address to store the interface pointer at
2160  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2161  *            aggregation, so it has to be NULL
2162  *
2163  * Returns:
2164  *  DD_OK on success
2165  *  CLASS_E_NOAGGREGATION if UnkOuter != NULL
2166  *  DDERR_* if an error occurs
