 585  * When the surface is a texture, the WineD3DTexture is released.
 586  * If the surface is the Direct3D render target, then the D3D
 587  * capabilities of the WineD3DDevice are uninitialized, which causes the

1802  * IDirectDrawSurface7::AddAttachedSurface
1803  *
1804  * Attaches a surface to another surface. How the surface attachments work
1805  * is not totally understood yet, and this method is prone to problems.
1806  * The surface that is attached is AddRef-ed.
1807  *
1808  * Tests with complex surfaces suggest that the surface attachments form a
1809  * tree, but no method to test this has been found yet.
1810  *
1811  * The attachment list consists of a first surface (first_attached) and
1812  * for each surface a pointer to the next attached surface (next_attached).
1813  * For the first surface, and a surface that has no attachments
1814  * first_attached points to the surface itself. A surface that has
1815  * no successors in the chain has next_attached set to NULL.
1816  *
1817  * Newly attached surfaces are attached right after the root surface.
1818  * If a surface is attached to a complex surface compound, it's attached to
1819  * the surface that the app requested, not the complex root. See
1820  * GetAttachedSurface for a description how surfaces are found.
1821  *
1822  * This is how the current implementation works, and it was coded by looking
1823  * at the needs of the applications.
1824  *
1825  * So far only Z-Buffer attachments are tested, and they are activated in
1826  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1827  * Back buffers should work in 2D mode, but they are not tested(They can be
1828  * attached in older iface versions). Rendering to the front buffer and
1829  * switching between that and double buffering is not yet implemented in
1830  * WineD3D, so for 3D it might have unexpected results.
1831  *
1832  * ddraw_surface_attach_surface is the real thing,
1833  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1834  * performs additional checks. Version 7 of this interface is much more restrictive
1835  * than its predecessors.
1836  *
1837  * Params:
1838  *  Attach: Surface to attach to iface
1839  *
1840  * Returns:
1841  *  DD_OK on success
1842  *  DDERR_CANNOTATTACHSURFACE if the surface can't be attached for some reason
