2141  * Creates a new IDirectDrawSurface object and returns its interface.
2142  *
2143  * The surface connections with wined3d are a bit tricky. Basically it works

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

2203  * Params:

2205  *  Surf: Address to store the interface pointer at
2206  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2207  *            aggregation, so it has to be NULL
2208  *
