I see, I'll have to look more into that, on a slightly unrelated 
note, any idea what's going on with glfwCreateWindow, it keeps 
wanting to be null while it's supposed to be an adddress.

this.get = glfwCreateWindow(settings.width, settings.height,
	toStringz(settings.title), this.monitor, this.share);
			
writeln(this.get);

That writeln will give me null, is it related to all this stuff?
