 * 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_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)
