// Generally we try to NOT provide any kind of superfluous high-level helpers in the examples.
// But for the purpose of allowing multi-windows, we need those internally anyway. The code being not trivial are exposing it for the benefit of the example code.
// If your application/engine already has code to create all that data (swap chain, render pass, frame buffers, etc.) you can ignore all of this.
