* What is known about cooperative levels (See the ddraw modes test):
* DDSCL_EXCLUSIVE and DDSCL_FULLSCREEN must be used with each other
* DDSCL_NORMAL is not compatible with DDSCL_EXCLUSIVE or DDSCL_FULLSCREEN
* DDSCL_SETFOCUSWINDOW can be passed only in DDSCL_NORMAL mode, but after that
* DDSCL_FULLSCREEN can be activated
* DDSCL_SETFOCUSWINDOW may only be used with DDSCL_NOWINDOWCHANGES
*
* Handled flags: DDSCL_NORMAL, DDSCL_FULLSCREEN, DDSCL_EXCLUSIVE,
* DDSCL_SETFOCUSWINDOW (partially),
* DDSCL_MULTITHREADED (work in progress)
*
* Unhandled flags, which should be implemented
* DDSCL_SETDEVICEWINDOW: Sets a window specially used for rendering (I don't
* expect any difference to a normal window for wine)
* DDSCL_CREATEDEVICEWINDOW: Tells ddraw to create its own window for
* rendering (Possible test case: Half-life)
*
* Unsure about these: DDSCL_FPUSETUP DDSCL_FPURESERVE
*
* These seem not really imporant for wine
* DDSCL_ALLOWREBOOT, DDSCL_NOWINDOWCHANGES, DDSCL_ALLOWMODEX

* Returns:
* DD_OK if the cooperative level was set successfully
* DDERR_INVALIDPARAMS if the passed cooperative level combination is invalid
* DDERR_HWNDALREADYSET if DDSCL_SETFOCUSWINDOW is passed in exclusive mode
* (Probably others too, have to investigate)

* | | | |
* | WineD3DSurface |-------------->| |
* | Child |<------------->| Parent |

* the WineD3DSurface when the ddraw surface is destroyed.
*
* However, for all surfaces which can be in a container in WineD3D,
* we have to do this. These surfaces are ususally complex surfaces,
* so this concerns primary surfaces with a front and a back buffer,
* and textures.
*
* |------------------------| |-----------------|
* | DDraw surface | | Containter |
* | | | |
* | Child |<------------->| Parent |
* | Texture |<------------->| |
* | WineD3DSurface |<----| | Levels |<--|

* | | Child |<---------->| Parent | |
* | |---------------------| | Container |<--|
* | |-----------------| |
* | |
* | ---More surfaces can follow--- |
*
* The reason is that the IWineD3DSwapchain(render target container)

* of their surface's children, but by releasing the complex root
* the surfaces which are complexly attached to it are destroyed
