 531  * and the refcount of the DirectDraw interface is reduced by 1. If it has

 534  * surface attached to it (with a "soft" attachment, not complex), then
 535  * this surface is detached with DeleteAttachedSurface.
 536  *
 537  * When the surface is a texture, the WineD3DTexture is released.
 538  * If the surface is the Direct3D render target, then the D3D
 539  * capabilities of the WineD3DDevice are uninitialized, which causes the
 540  * swapchain to be released.
