-- == Description
--
-- The @VK_EXT_directfb_surface@ extension is an instance extension. It
-- provides a mechanism to create a 'Vulkan.Extensions.Handles.SurfaceKHR'
-- object (defined by the @VK_KHR_surface@ extension) that refers to a
-- DirectFB 'IDirectFBSurface', as well as a query to determine support for
-- rendering via DirectFB.
--
-- == New Commands
--
-- -   'createDirectFBSurfaceEXT'
--
-- -   'getPhysicalDeviceDirectFBPresentationSupportEXT'
--
-- == New Structures
--
-- -   'DirectFBSurfaceCreateInfoEXT'
--
-- == New Bitmasks
--
-- -   'DirectFBSurfaceCreateFlagsEXT'
--
-- == New Enum Constants
--
-- -   'EXT_DIRECTFB_SURFACE_EXTENSION_NAME'
--
-- -   'EXT_DIRECTFB_SURFACE_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_DIRECTFB_SURFACE_CREATE_INFO_EXT'
