 * 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 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 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)
