That's just it... I don't know how to set the width/height to the screen extents, would it be something like this:
windowLayout.Set(tk2dCamera.Instance.ScreenExtents.xMin, tk2dCamera.Instance.ScreenExtents.yMin, 0)
windowLayout.Set(tk2dCamera.Instance.ScreenExtents.xMax, tk2dCamera.Instance.ScreenExtents.yMax, 0)
??
