 521  * Reduces the surface's refcount by 1. If the refcount falls to 0, the

 523  *
 524  * Destroying the surface is a bit tricky. For the connection between
 525  * WineD3DSurfaces and DirectDrawSurfaces see IDirectDraw7::CreateSurface
 526  * It has a nice graph explaining the connection.
 527  *
 528  * What happens here is basically this:
 529  * When a surface is destroyed, its WineD3DSurface is released,
 530  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 531  * complex surfaces attached to it, then these surfaces are destroyed too,
 532  * regardless of their refcount. If any surface being destroyed has another
 533  * surface attached to it (with a "soft" attachment, not complex), then
 534  * this surface is detached with DeleteAttachedSurface.
 535  *
 536  * When the surface is a texture, the WineD3DTexture is released.
 537  * If the surface is the Direct3D render target, then the D3D
 538  * capabilities of the WineD3DDevice are uninitialized, which causes the
 539  * swapchain to be released.
 540  *
 541  * When a complex sublevel falls to ref zero, then this is ignored.

1506  *
1507  * Attaches a surface to another surface. How the surface attachments work
1508  * is not totally understood yet, and this method is prone to problems.
1509  * The surface that is attached is AddRef-ed.
1510  *
1511  * Tests with complex surfaces suggest that the surface attachments form a
1512  * tree, but no method to test this has been found yet.
1513  *
1514  * The attachment list consists of a first surface (first_attached) and
1515  * for each surface a pointer to the next attached surface (next_attached).
1516  * For the first surface, and a surface that has no attachments
1517  * first_attached points to the surface itself. A surface that has
1518  * no successors in the chain has next_attached set to NULL.
1519  *
1520  * Newly attached surfaces are attached right after the root surface.
1521  * If a surface is attached to a complex surface compound, it's attached to
1522  * the surface that the app requested, not the complex root. See
1523  * GetAttachedSurface for a description how surfaces are found.
1524  *
1525  * This is how the current implementation works, and it was coded by looking
1526  * at the needs of the applications.
1527  *
1528  * So far only Z-Buffer attachments are tested, and they are activated in
1529  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1530  * Back buffers should work in 2D mode, but they are not tested(They can be
1531  * attached in older iface versions). Rendering to the front buffer and
1532  * switching between that and double buffering is not yet implemented in
1533  * WineD3D, so for 3D it might have unexpected results.
1534  *
