Description
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.
