This API is the initial public release of the composition swapchain API. It allows applications using Composition APIs (such as Windows.UI.Composition and DirectComposition) to host content that can be independently rendered and presented to. In many ways, this type of presented content is conceptually similar to a DXGI swapchain. Both offer the ability to render to a buffer, and then present that buffer to the screen. However, the composition swapchain API offers the ability for presents to target a specific time to appear (the PresentAt time), whereas DXGI doesn't, and the composition swapchain API offers more freedom than DXGI around the ordering of buffers available to be presented.
The focus of the initial version of this API is to enable media frameworks, such as Windows Media Foundation, to effectively use timed presentation.
