2106  * IDirectDraw7::CreateSurface
2107  *
2108  * Creates a new IDirectDrawSurface object and returns its interface.
2109  *
2110  * The surface connections with wined3d are a bit tricky. Basically it works
2111  * like this:

2118  * |------------------------|               |-----------------|
2119  *
2120  * The DDraw surface is the parent of the wined3d surface, and it releases
2121  * the WineD3DSurface when the ddraw surface is destroyed.
2122  *
2123  * However, for all surfaces which can be in a container in WineD3D,
2124  * we have to do this. These surfaces are usually complex surfaces,
2125  * so this concerns primary surfaces with a front and a back buffer,
2126  * and textures.

2168  * explanation.
2169  *
2170  * Params:
2171  *  DDSD: Description of the surface to create
2172  *  Surf: Address to store the interface pointer at
2173  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2174  *            aggregation, so it has to be NULL
2175  *
