2105  * IDirectDraw7::CreateSurface
2106  *
2107  * Creates a new IDirectDrawSurface object and returns its interface.
2108  *
2109  * The surface connections with wined3d are a bit tricky. Basically it works
2110  * like this:

2112  * |------------------------|               |-----------------|

2117  * |------------------------|               |-----------------|
2118  *
2119  * The DDraw surface is the parent of the wined3d surface, and it releases
2120  * the WineD3DSurface when the ddraw surface is destroyed.
2121  *
2122  * However, for all surfaces which can be in a container in WineD3D,
2123  * we have to do this. These surfaces are usually complex surfaces,
2124  * so this concerns primary surfaces with a front and a back buffer,
2125  * and textures.

2167  * explanation.
2168  *
2169  * Params:
2170  *  DDSD: Description of the surface to create
2171  *  Surf: Address to store the interface pointer at
2172  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2173  *            aggregation, so it has to be NULL
2174  *
