/// - OnResize (create there your frame buffers couple to the swapchain and trigger the recording of your command buffers for the presentation.
/// - UpdateView (generaly used when the camera setup has changed to update MVP matrices)
/// The rendering loop consist of the following steps:
/// - render (the default one will submit the default command buffers to the presentQueue and trigger a queue present for each swapchain images.
/// - if the `updateViewRequested` field is set to 'true', call the `UpdateView` method.
/// - frame counting and chrono.
/// - if elapsed time reached `UpdateFrequency` value, the `Update` method is called and the elapsed time chrono is reseet.
/// - GLFW events are polled at the end of the loop.
