Easy way to check if DirectX is used as renderer (instead of Open GL or Open GL ES)

Title says it all, is the a simple way in code to check if Unity uses Direct X instead of Open GL (note that even on windows you can have unity run on Open GL, so just `UNITY_STANDALONE_WIN` isn't enough).

Thanks and happy new year! Jaap

The most reliable way I can find is `SystemInfo.graphicsDeviceVersion.StartsWith("Direct")` is there a better way?
