 531  * Destroying the surface is a bit tricky. For the connection between

 535  * What happens here is basically this:
 536  * When a surface is destroyed, its WineD3DSurface is released,
 537  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 538  * complex surfaces attached to it, then these surfaces are destroyed too,
 539  * regardless of their refcount. If any surface being destroyed has another
 540  * surface attached to it (with a "soft" attachment, not complex), then
 541  * this surface is detached with DeleteAttachedSurface.
 542  *
 543  * When the surface is a texture, the WineD3DTexture is released.
 544  * If the surface is the Direct3D render target, then the D3D
 545  * capabilities of the WineD3DDevice are uninitialized, which causes the
 546  * swapchain to be released.

1525  *
1526  * Attaches a surface to another surface. How the surface attachments work
1527  * is not totally understood yet, and this method is prone to problems.
1528  * The surface that is attached is AddRef-ed.
1529  *
1530  * Tests with complex surfaces suggest that the surface attachments form a
1531  * tree, but no method to test this has been found yet.
1532  *
1533  * The attachment list consists of a first surface (first_attached) and
1534  * for each surface a pointer to the next attached surface (next_attached).
1535  * For the first surface, and a surface that has no attachments
1536  * first_attached points to the surface itself. A surface that has
1537  * no successors in the chain has next_attached set to NULL.
1538  *
1539  * Newly attached surfaces are attached right after the root surface.
1540  * If a surface is attached to a complex surface compound, it's attached to
1541  * the surface that the app requested, not the complex root. See
1542  * GetAttachedSurface for a description how surfaces are found.
1543  *
1544  * This is how the current implementation works, and it was coded by looking
1545  * at the needs of the applications.
1546  *
1547  * So far only Z-Buffer attachments are tested, and they are activated in
1548  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1549  * Back buffers should work in 2D mode, but they are not tested(They can be
1550  * attached in older iface versions). Rendering to the front buffer and
1551  * switching between that and double buffering is not yet implemented in
1552  * WineD3D, so for 3D it might have unexpected results.
1553  *
1554  * ddraw_surface_attach_surface is the real thing,
