-- == Description
--
-- A memory barrier /may/ have a performance penalty when acquiring
-- ownership of a subresource range from an external queue family. This
-- extension provides API that /may/ reduce the performance penalty if
-- ownership of the subresource range was previously released to the
-- external queue family and if the resource’s memory has remained
-- unmodified between the release and acquire operations.

-- -   'EXT_EXTERNAL_MEMORY_ACQUIRE_UNMODIFIED_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
