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

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

1520  * Newly attached surfaces are attached right after the root surface.
