--
-- == Description
--
-- The @VK_QNX_screen_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 QNX
-- Screen @window@, as well as a query to determine support for rendering
-- to a QNX Screen compositor.
--
-- == New Commands
--
-- -   'createScreenSurfaceQNX'
--
-- -   'getPhysicalDeviceScreenPresentationSupportQNX'
--
-- == New Structures
--
-- -   'ScreenSurfaceCreateInfoQNX'
--
-- == New Bitmasks
--
-- -   'ScreenSurfaceCreateFlagsQNX'
--
-- == New Enum Constants
--
-- -   'QNX_SCREEN_SURFACE_EXTENSION_NAME'
--
-- -   'QNX_SCREEN_SURFACE_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_SCREEN_SURFACE_CREATE_INFO_QNX'
--
-- == Version History
--
-- -   Revision 1, 2021-01-11 (Mike Gorchak)
--
--     -   Initial draft.
