2140  * IDirectDraw7::CreateSurface
2141  *
2142  * Creates a new IDirectDrawSurface object and returns its interface.
2143  *
2144  * The surface connections with wined3d are a bit tricky. Basically it works
2145  * like this:

2152  * |------------------------|               |-----------------|
2153  *
2154  * The DDraw surface is the parent of the wined3d surface, and it releases
2155  * the WineD3DSurface when the ddraw surface is destroyed.
2156  *
2157  * However, for all surfaces which can be in a container in WineD3D,
2158  * we have to do this. These surfaces are ususally complex surfaces,
2159  * so this concerns primary surfaces with a front and a back buffer,
2160  * and textures.

2203  *
2204  * Params:
2205  *  DDSD: Description of the surface to create
2206  *  Surf: Address to store the interface pointer at
2207  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2208  *            aggregation, so it has to be NULL
2209  *
