2152  * Creates a new IDirectDrawSurface object and returns its interface.
2153  *
2154  * The surface connections with wined3d are a bit tricky. Basically it works

2163  *
2164  * The DDraw surface is the parent of the wined3d surface, and it releases
2165  * the WineD3DSurface when the ddraw surface is destroyed.
2166  *
2167  * However, for all surfaces which can be in a container in WineD3D,
2168  * we have to do this. These surfaces are ususally complex surfaces,
2169  * so this concerns primary surfaces with a front and a back buffer,

2216  *  Surf: Address to store the interface pointer at
2217  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2218  *            aggregation, so it has to be NULL
2219  *
