--
-- == Description
--
-- An application using external memory may wish to synchronize access to
-- that memory using semaphores. This extension enables an application to
-- export semaphore payload to and import semaphore payload from Zircon
-- event handles.
--
-- == New Commands
--
-- -   'getSemaphoreZirconHandleFUCHSIA'
--
-- -   'importSemaphoreZirconHandleFUCHSIA'
--
-- == New Structures
--
-- -   'ImportSemaphoreZirconHandleInfoFUCHSIA'
--
-- -   'SemaphoreGetZirconHandleInfoFUCHSIA'
--
-- == New Enum Constants
--
-- -   'FUCHSIA_EXTERNAL_SEMAPHORE_EXTENSION_NAME'
--
-- -   'FUCHSIA_EXTERNAL_SEMAPHORE_SPEC_VERSION'
--
-- -   Extending
--     'Vulkan.Core11.Enums.ExternalSemaphoreHandleTypeFlagBits.ExternalSemaphoreHandleTypeFlagBits':
--
--     -   'Vulkan.Core11.Enums.ExternalSemaphoreHandleTypeFlagBits.EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT_FUCHSIA'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_IMPORT_SEMAPHORE_ZIRCON_HANDLE_INFO_FUCHSIA'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_SEMAPHORE_GET_ZIRCON_HANDLE_INFO_FUCHSIA'
--
-- == Issues
--
-- 1) Does the application need to close the Zircon event handle returned
-- by 'getSemaphoreZirconHandleFUCHSIA'?
--
-- __RESOLVED__: Yes, unless it is passed back in to a driver instance to
-- import the semaphore. A successful get call transfers ownership of the
-- Zircon event handle to the application, and a successful import
-- transfers it back to the driver. Destroying the original semaphore
-- object will not close the Zircon event handle nor remove its reference
-- to the underlying semaphore resource associated with it.
