Issues
1) Is there a query interface to check if a swapchain is using the present barrier?
RESOLVED. There is no such query interface. When creating a swapchain, an application can specify to use the present barrier, and if the swapchain is created successfully, this swapchain will be using the present barrier.
2) Do we need an extra interface to set up the present barrier across distributed systems?
RESOLVED. If the required hardware is presented in the system, and all settings for the physical synchronization with other systems are set up, an implementation manages the configuration automatically when creating a swapchain, without any extra calls from the application.
