/*****************************************************************************
* IDirectDraw7::CreateSurface
*
* Creates a new IDirectDrawSurface object and returns its interface.
*
* The surface connections with wined3d are a bit tricky. Basically it works
* like this:
*
* |------------------------| |-----------------|
* | DDraw surface | | WineD3DSurface |
* | | | |
* | WineD3DSurface |-------------->| |
* | Child |<------------->| Parent |
* |------------------------| |-----------------|
*
* The DDraw surface is the parent of the wined3d surface, and it releases
* the WineD3DSurface when the ddraw surface is destroyed.
*
* However, for all surfaces which can be in a container in WineD3D,
* we have to do this. These surfaces are usually complex surfaces,
* so this concerns primary surfaces with a front and a back buffer,
* and textures.
*
* |------------------------| |-----------------|
* | DDraw surface | | Container |
* | | | |
* | Child |<------------->| Parent |
* | Texture |<------------->| |
* | WineD3DSurface |<----| | Levels |<--|
* | Complex connection | | | | |
* |------------------------| | |-----------------| |
* ^ | |
* | | |
* | | |
* | |------------------| | |-----------------| |
* | | IParent | |-------->| WineD3DSurface | |
* | | | | | |
* | | Child |<------------->| Parent | |
* | | | | Container |<--|
* | |------------------| |-----------------| |
* | |
* | |----------------------| |
* | | DDraw surface 2 | |
* | | | |
* |<->| Complex root Child | |
* | | Texture | |
* | | WineD3DSurface |<----| |
* | |----------------------| | |
* | | |
* | |---------------------| | |-----------------| |
* | | IParent | |----->| WineD3DSurface | |
* | | | | | |
* | | Child |<---------->| Parent | |
* | |---------------------| | Container |<--|
* | |-----------------| |
* | |
* | ---More surfaces can follow--- |
*
* The reason is that the IWineD3DSwapchain(render target container)
* and the IWineD3DTexure(Texture container) release the parents
* of their surface's children, but by releasing the complex root
* the surfaces which are complexly attached to it are destroyed
* too. See IDirectDrawSurface::Release for a more detailed
* explanation.
*
* Params:
* DDSD: Description of the surface to create
* Surf: Address to store the interface pointer at
* UnkOuter: Basically for aggregation support, but ddraw doesn't support
* aggregation, so it has to be NULL
*
* Returns:
* DD_OK on success
* CLASS_E_NOAGGREGATION if UnkOuter != NULL
* DDERR_* if an error occurs
*
