Init() public static method

Initializes OpenTK. This method is necessary only if you are using OpenTK alongside a different windowing toolkit (e.g. GTK#) and should be the very first method called by your application (i.e. calling this method should be the very first statement executed by the "Main" method).
Some windowing toolkits do not configure the underlying platform correctly or configure it in a way that is incompatible with OpenTK. Calling this method first ensures that OpenTK is given the chance to initialize itself and configure the platform correctly.
