--
-- == Description
--
-- This extension allows the
-- 'Vulkan.Extensions.VK_KHR_surface.getPhysicalDeviceSurfaceFormatsKHR'
-- and
-- 'Vulkan.Extensions.VK_KHR_surface.getPhysicalDeviceSurfacePresentModesKHR'
-- functions to accept 'Vulkan.Core10.APIConstants.NULL_HANDLE' as their
-- @surface@ parameter, allowing potential surface formats, colorspaces and
-- present modes to be queried without providing a surface. Identically,
-- 'Vulkan.Extensions.VK_KHR_get_surface_capabilities2.getPhysicalDeviceSurfaceFormats2KHR'
-- and
-- 'Vulkan.Extensions.VK_EXT_full_screen_exclusive.getPhysicalDeviceSurfacePresentModes2EXT'
-- would accept 'Vulkan.Core10.APIConstants.NULL_HANDLE' in
-- 'Vulkan.Extensions.VK_KHR_get_surface_capabilities2.PhysicalDeviceSurfaceInfo2KHR'::@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__.
