  *
  * Restores the display mode to what it was at creation time. Basically.
  *
- * A problem arises when there are 2 DirectDraw objects using the same hwnd:
- *  -> DD_1 finds the screen at 1400x1050x32 when created, sets it to 640x480x16
- *  -> DD_2 is created, finds the screen at 640x480x16, sets it to 1024x768x32
- *  -> DD_1 is released. The screen should be left at 1024x768x32.
- *  -> DD_2 is released. The screen should be set to 1400x1050x32
- * This case is unhandled right now, but Empire Earth does it this way.
- * (But perhaps there is something in SetCooperativeLevel to prevent this)
- *
- * The msdn says that this method resets the display mode to what it was before
- * SetDisplayMode was called. What if SetDisplayModes is called 2 times??
- *
  * Returns
  *  DD_OK on success
  *  DDERR_NOEXCLUSIVE mode if the device isn't in fullscreen mode
