Missing script reference for static function of Camera

I have found a class function for Camera, which is not in the Unity Script Reference.

This is the C# declaration of the method:

public static void SetupCurrent(Camera cur);

I am using Unity 4.5.4f1. Does anyone know what this method is supposed to do?

We occasionally make mistakes and have public API functions which haven’t been documented. In this case, it’s not documented for a reason, and that reason is we don’t want people calling this. It’s public because some hairy details of the terrain editor need to do strange things.
