--
-- == Description
--
-- An application using external memory may wish to synchronize access to
-- that memory using semaphores. This extension enables an application to
-- create semaphores from which non-Vulkan handles that reference the
-- underlying synchronization primitive can be exported.
--
-- == Promotion to Vulkan 1.1
--
-- All functionality in this extension is included in core Vulkan 1.1, with
-- the KHR suffix omitted. The original type, enum and command names are
-- still available as aliases of the core functionality.
--
-- == New Structures
--
-- -   Extending 'Vulkan.Core10.QueueSemaphore.SemaphoreCreateInfo':
--
--     -   'ExportSemaphoreCreateInfoKHR'
--
-- == New Enums
--
-- -   'SemaphoreImportFlagBitsKHR'
--
-- == New Bitmasks
--
-- -   'SemaphoreImportFlagsKHR'
--
-- == New Enum Constants
--
-- -   'KHR_EXTERNAL_SEMAPHORE_EXTENSION_NAME'
--
-- -   'KHR_EXTERNAL_SEMAPHORE_SPEC_VERSION'
--
-- -   Extending
--     'Vulkan.Core11.Enums.SemaphoreImportFlagBits.SemaphoreImportFlagBits':
--
--     -   'SEMAPHORE_IMPORT_TEMPORARY_BIT_KHR'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'STRUCTURE_TYPE_EXPORT_SEMAPHORE_CREATE_INFO_KHR'
--
-- == Issues
--
-- 1) Should there be restrictions on what side effects can occur when
-- waiting on imported semaphores that are in an invalid state?
--
-- __RESOLVED__: Yes. Normally, validating such state would be the
-- responsibility of the application, and the implementation would be free
-- to enter an undefined state if valid usage rules were violated. However,
-- this could cause security concerns when using imported semaphores, as it
-- would require the importing application to trust the exporting
-- application to ensure the state is valid. Requiring this level of trust
-- is undesirable for many potential use cases.
--
-- 2) Must implementations validate external handles the application
-- provides as input to semaphore state import operations?
--
-- __RESOLVED__: Implementations must return an error to the application if
-- the provided semaphore state handle cannot be used to complete the
-- requested import operation. However, implementations need not validate
-- handles are of the exact type specified by the application.
