--
-- == Description
--
-- @VK_KHR_ray_tracing_position_fetch@ adds the ability to fetch the vertex
-- positions in the shader from a hit triangle as stored in the
-- acceleration structure.
--
-- An application adds
-- 'Vulkan.Extensions.VK_KHR_acceleration_structure.BUILD_ACCELERATION_STRUCTURE_ALLOW_DATA_ACCESS_KHR'
-- to the acceleration structure at build time. Then, if the hit is a
-- triangle geometry, the shader (any-hit or closest hit for ray pipelines
-- or using ray query) /can/ fetch the three, three-component vertex
-- positions in object space, of the triangle which was hit.
