Call sio2InitGL

Hi,

I wonder does it cause memory leak or other problem if I call sio2InitGL more than once, actually I don't find any method like sio2ShutDownGL, so I suppose sio2InitGL doesn't malloc any new memory.
Am Ｉ　ｒｉｇｈｔ？

Basically initGL just set some machine states to the default that SIO2 expect them... and that's it... the initialization of the GL context for the targeted platform is out of the scope of SIO2.
