2145  *
2146  * The surface connections with wined3d are a bit tricky. Basically it works

2156  * The DDraw surface is the parent of the wined3d surface, and it releases
2157  * the WineD3DSurface when the ddraw surface is destroyed.
2158  *
2159  * However, for all surfaces which can be in a container in WineD3D,
2160  * we have to do this. These surfaces are usually complex surfaces,
2161  * so this concerns primary surfaces with a front and a back buffer,

2209  *  UnkOuter: Basically for aggregation support, but ddraw doesn't support
2210  *            aggregation, so it has to be NULL
