2097  * IDirectDraw7::CreateSurface
2098  *
2099  * Creates a new IDirectDrawSurface object and returns its interface.
2100  *
2101  * The surface connections with wined3d are a bit tricky. Basically it works
2102  * like this:

2109  * |------------------------|               |-----------------|
2110  *
2111  * The DDraw surface is the parent of the wined3d surface, and it releases
2112  * the WineD3DSurface when the ddraw surface is destroyed.
2113  *
2114  * However, for all surfaces which can be in a container in WineD3D,
2115  * we have to do this. These surfaces are usually complex surfaces,
2116  * so this concerns primary surfaces with a front and a back buffer,
2117  * and textures.

2159  * explanation.
2160  *
2161  * Params:
2162  *  DDSD: Description of the surface to create
2163  *  Surf: Address to store the interface pointer at
2164  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2165  *            aggregation, so it has to be NULL
2166  *
