 * IDirectDraw7::SetCooperativeLevel
 *
 * Sets the cooperative level for the DirectDraw object, and the window
 * assigned to it. The cooperative level determines the general behavior
 * of the DirectDraw application
 *
 * Warning: This is quite tricky, as it's not really documented which
 * cooperative levels can be combined with each other. If a game fails
 * after this function, try to check the cooperative levels passed on
 * Windows, and if it returns something different.
 *
 * If you think that this function caused the failure because it writes a
 * fixme, be sure to run again with a +ddraw trace.
 *
 * What is known about cooperative levels (See the ddraw modes test):
 * DDSCL_EXCLUSIVE requires DDSCL_FULLSCREEN.
 * DDSCL_NORMAL is not compatible with DDSCL_EXCLUSIVE.
 * Unlike what msdn claims, DDSCL_NORMAL | DDSCL_FULLSCREEN is allowed.
 * DDSCL_SETFOCUSWINDOW can be passed only in DDSCL_NORMAL mode, but after that
 * DDSCL_EXCLUSIVE can be activated.
 * DDSCL_SETFOCUSWINDOW may only be used with DDSCL_NOWINDOWCHANGES or
 * DDSCL_CREATEDEVICEWINDOW.
 *
 * Handled flags: DDSCL_NORMAL, DDSCL_FULLSCREEN, DDSCL_EXCLUSIVE,
 *                DDSCL_CREATEDEVICEWINDOW, DDSCL_SETDEVICEWINDOW
 *                DDSCL_SETFOCUSWINDOW (partially),
 *                DDSCL_MULTITHREADED (work in progress)
 *                DDSCL_FPUPRESERVE (see device.c)
 *
 * Unsure about this: DDSCL_FPUSETUP
 *
 * These don't seem very important for wine:
 *  DDSCL_ALLOWREBOOT, 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)

     * because ddraw only supports 16 bit indices.
     *
     * Some games, for example Prince of Persia 3D (bug 44863), create a
     * vertex buffer to hold as many vertices as we report here. The
     * game requests a video memory buffer, maps it, writes a handful
     * of vertices and draws. Because IDirect3DVertexBuffer::Lock does
     * not allow passing a range, and prior to d3d7 doesn't support
     * NOOVERWRITE/DISCARD, the upload becomes slow if the buffer is too
     * large. So we don't want to report a value that's too high here.
     *
     * Why 2048? Windows 9x was the contemporaneous system when d3d 1-4
     * titles were written.
     *
     * Regardless of this value, we put ddraw4 vertex buffers into
     * system memory because games are using them poorly. This mitigates
     * negative effects of a large vertex count.
     *
     * Windows doesn't enforce this limit. A larger vertex buffer can
     * be created and used in draws. More vertices than dwMaxVertexCount
     * can be rendered in one draw call. SetExecuteData with a vertex
     * count exceeding dwMaxVertexCount succeeds too. */
