This extension allows the vkGetPhysicalDeviceSurfaceFormatsKHR and vkGetPhysicalDeviceSurfacePresentModesKHR functions to accept VK_NULL_HANDLE as their surface parameter, allowing potential surface formats, color spaces and present modes to be queried without providing a surface. Identically, vkGetPhysicalDeviceSurfaceFormats2KHR, vkGetPhysicalDeviceSurfacePresentModes2EXT, and vkGetPhysicalDeviceSurfaceCapabilities2KHR would accept VK_NULL_HANDLE in VkPhysicalDeviceSurfaceInfo2KHR::surface. This can only be supported on platforms where the results of these queries are surface-agnostic and a single presentation engine is the implicit target of all present operations.
