--
-- == Description
--
-- An application using external memory may wish to synchronize access to
-- that memory using fences. This extension enables an application to
-- export fence payload to and import fence payload from Windows handles.
--
-- == New Commands
--
-- -   'getFenceWin32HandleKHR'
--
-- -   'importFenceWin32HandleKHR'
--
-- == New Structures
--
-- -   'FenceGetWin32HandleInfoKHR'
--
-- -   'ImportFenceWin32HandleInfoKHR'
--
-- -   Extending 'Vulkan.Core10.Fence.FenceCreateInfo':
--
--     -   'ExportFenceWin32HandleInfoKHR'
--
-- == New Enum Constants
--
-- -   'KHR_EXTERNAL_FENCE_WIN32_EXTENSION_NAME'
--
-- -   'KHR_EXTERNAL_FENCE_WIN32_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_EXPORT_FENCE_WIN32_HANDLE_INFO_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_FENCE_GET_WIN32_HANDLE_INFO_KHR'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_FENCE_WIN32_HANDLE_INFO_KHR'
--
-- == Issues
--
-- This extension borrows concepts, semantics, and language from
-- @VK_KHR_external_semaphore_win32@. That extension’s issues apply equally
-- to this extension.
--
-- 1) Should D3D12 fence handle types be supported, like they are for
-- semaphores?
--
-- __RESOLVED__: No. Doing so would require extending the fence signal and
-- wait operations to provide values to signal \/ wait for, like
-- 'Vulkan.Extensions.VK_KHR_external_semaphore_win32.D3D12FenceSubmitInfoKHR'
-- does. A D3D12 fence can be signaled by importing it into a
-- 'Vulkan.Core10.Handles.Semaphore' instead of a
-- 'Vulkan.Core10.Handles.Fence', and applications can check status or wait
-- on the D3D12 fence using non-Vulkan APIs. The convenience of being able
-- to do these operations on 'Vulkan.Core10.Handles.Fence' objects does not
-- justify the extra API complexity.
