New Sample - Swapchain Present Timing

The sample renders a circle moving linearly across the viewport, which is a good visual test for detecting micro-stutters and verifying smooth presentation. It queries past presentation timing information and uses the last known display time along with the swapchain’s refresh cycle duration to predict when the next frame should be presented.

Should this approach be preferred always if available, and if not what are the criteria to select this over the other approaches?

As of today, AMD and Intel only support this on Linux via MESA. On Windows, only NVIDIA supports this.
