This extension extends VkSurfaceCapabilities2KHR, providing
applications a way to query whether swapchains can be created with the
VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set.
Vulkan 1.1 added (optional) support for protect memory and protected
resources including buffers (
VK_IMAGE_CREATE_PROTECTED_BIT), and swapchains
However, on implementations which support multiple windowing systems, not
all window systems may be able to provide a protected display path.
This extension provides a way to query if a protected swapchain created for a surface (and thus a specific windowing system) can be displayed on screen. It extends the existing VkSurfaceCapabilities2KHR structure with a new VkSurfaceProtectedCapabilitiesKHR structure from which the application can obtain information about support for protected swapchain creation through vkGetPhysicalDeviceSurfaceCapabilities2KHR.
