--
-- == Description
--
-- This device extension allows an application that uses the
-- @VK_KHR_swapchain@ extension to obtain information about the
-- presentation engine’s display, to obtain timing information about each
-- present, and to schedule a present to happen no earlier than a desired
-- time. An application can use this to minimize various visual anomalies
-- (e.g. stuttering).
--
-- Traditional game and real-time animation applications need to correctly
-- position their geometry for when the presentable image will be presented
-- to the user. To accomplish this, applications need various timing
-- information about the presentation engine’s display. They need to know
-- when presentable images were actually presented, and when they could
-- have been presented. Applications also need to tell the presentation
-- engine to display an image no sooner than a given time. This allows the
-- application to avoid stuttering, so the animation looks smooth to the
-- user.
--
-- This extension treats variable-refresh-rate (VRR) displays as if they
-- are fixed-refresh-rate (FRR) displays.
--
-- == New Commands
--
-- -   'getPastPresentationTimingGOOGLE'
--
-- -   'getRefreshCycleDurationGOOGLE'
--
-- == New Structures
--
-- -   'PastPresentationTimingGOOGLE'
--
-- -   'PresentTimeGOOGLE'
--
-- -   'RefreshCycleDurationGOOGLE'
--
-- -   Extending 'Vulkan.Extensions.VK_KHR_swapchain.PresentInfoKHR':
--
--     -   'PresentTimesInfoGOOGLE'
--
-- == New Enum Constants
--
-- -   'GOOGLE_DISPLAY_TIMING_EXTENSION_NAME'
--
-- -   'GOOGLE_DISPLAY_TIMING_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PRESENT_TIMES_INFO_GOOGLE'
--
-- == Examples
--
-- Note
--
-- The example code for the this extension (like the @VK_KHR_surface@ and
-- @VK_GOOGLE_display_timing@ extensions) is contained in the cube demo
-- that is shipped with the official Khronos SDK, and is being kept
-- up-to-date in that location (see:
-- <https://github.com/KhronosGroup/Vulkan-Tools/blob/master/cube/cube.c>
-- ).
