12  This extension extends slink:VkSurfaceCapabilities2KHR, providing
13  applications a way to query whether swapchains can: be created with the
14  ename:VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set.
15  
16  Vulkan 1.1 added (optional) support for protect memory and protected
17  resources including buffers (ename:VK_BUFFER_CREATE_PROTECTED_BIT), images
18  (ename:VK_IMAGE_CREATE_PROTECTED_BIT), and swapchains
19  (ename:VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR).
20  However, on implementations which support multiple windowing systems, not
21  all window systems may: be able to provide a protected display path.
22  
23  This extension provides a way to query if a protected swapchain created for
24  a surface (and thus a specific windowing system) can: be displayed on
25  screen.
26  It extends the existing slink:VkSurfaceCapabilities2KHR structure with a new
27  slink:VkSurfaceProtectedCapabilitiesKHR structure from which the application
28  can: obtain information about support for protected swapchain creation
29  through flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
