//WHY do we have to do this? some intel graphics drivers (ig7icd64.dll 10.18.10.3304 on an unknown chip on win8.1) are calling SetDllDirectory() for the process, which ruins stuff.
//The relevant initialization happened just before in "create IGL context".
//It isn't clear whether we need the earlier SetDllDirectory(), but I think we do.
//note: this is pasted instead of being put in a static method due to this initialization code being sensitive to things like that, and not wanting to cause it to break
//pasting should be safe (not affecting the jit order of things)
