/* On Windows one can force the refresh rate that DirectDraw uses by
* setting an override value in dxdiag. This is documented in KB315614
* (main article), KB230002, and KB217348. By comparing registry dumps
* before and after setting the override, we see that the override value
* is stored in HKLM\Software\Microsoft\DirectDraw\ForceRefreshRate as a
* DWORD that represents the refresh rate to force. We use this
* registry entry to modify the behavior of SetDisplayMode so that Wine
* users can override the refresh rate in a Windows-compatible way.
*
* dxdiag will not accept a refresh rate lower than 40 or higher than
* 120 so this value should be within that range. It is, of course,
* possible for a user to set the registry entry value directly so that
* assumption might not hold.
*
* There is no current mechanism for setting this value through the Wine
* GUI. It would be most appropriate to set this value through a dxdiag
* clone, but it may be sufficient to use winecfg.
*
* TODO: Create a mechanism for setting this value through the Wine GUI.
